The identification of typical dermatofibroma is uncomplicated, although it can be challenge due to its wide range of presentations and histological variations. Objective: This study was undertaken to evaluate the clinical and histopathological characteristics of 147 Cases of Dermatofibroma. Methods: This is a retrospective study of 147 biopsy specimens of 124 patients who were diagnosed with dermatofibroma in the Department of Dermatology and the Department of Pathology at the Seventh Affiliated Hospital of Sun Yat-sen University between January 2009 and April 2024. All case were retrieved from the saved medical records. Results: Ages of the 124 Dermatofibroma-affected individuals ranged from 11 to 61 years with a male-to-female ratio of 1:1.7. Over 80% of the case occurred between the ages of 20 and 49 years, 61.9% of the lesions were found on the extremities. The duration of the cases varied from 17 days to 30 years and half of lesions (58.2%) persisted for less than two years. Over 60% of the lesions were found on the extremities. The diameter of the tumors ranged between 0.3 cm and 5 cm, with most tumors measuring less than or equal to 2 cm (85.00%). Cutaneous masses or dermatofibroma was the most common clinical diagnosis. Most tumors (79.6%) were asymptomatic. Cutaneous masses or dermatofibroma was the most common clinical diagnosis. Prior to the surgical procedure, 57 cases were suspected to be “DF”, 55 cases were suspected to be “cutaneous masses”. Immunohistochemical staining revealed positive expression of SMA, while the negative rate of CD34 was found to be 66.67%. No diffuse CD34 positivity was observed in all tumors. Conclusion: Variations in clinical features, pathological manifestations, and immunohistochemical results of DF pose challenges for accurate diagnosis. A comprehensive understanding of its clinical and pathological characteristics is crucial for precise identification. Incorporating immunohistochemical analysis can help prevent misdiagnosis.展开更多

Additionally, the imaging appearance of schwannomas resembles that of neurofibromas, making it difficult to distinguish between the two. Therefore, the clinical diagnosis and treatment of schwannomas may face certain challenges. The management and prognosis of neurilemmomas differ from their malignant counterparts, making correct diagnosis important. Objective: This study evaluates the clinical and histopathological characteristics of 45 cases of neurilemmoma. Methods: This retrospective study involves 45 cases diagnosed with cutaneous neurilemmoma at the Seventh Affiliated Hospital of Sun Yat-sen University between April 2020 and September 2024. All cases were retrieved from medical records. Results: The age range of the 45 patients was 23 to 73 years, with a male to female ratio of 1.6:1. Over half the cases occurred in individuals aged 30 to 59, with most lesions found in the extremities, predominantly in the lower limbs. Disease duration varied from 7 days to 20 years. All tumors were solitary, with diameters ranging from 0.8 cm to 8 cm. Most tumors (33/45, 73.33%) were asymptomatic, though some patients experienced symptoms like pain and numbness. Mass was the most common clinical diagnosis (33/45, 73.33%). Five patients had suspected neurilemmomas prior to surgery. Immunohistochemical staining revealed all positive results for S-100 and SOX-10 markers, while EMA staining showed a negative rate of 93.33%. Most Ki-67 values (19/23, 82.6%) were less than or equal to 5%. Conclusion: The diversity of clinical features, pathological manifestations, and immunohistochemical results of schwannoma poses a challenge to accurate diagnosis. A comprehensive understanding of its clinical and pathological characteristics is essential for accurate diagnosis, and when combined with immunohistochemical analysis, it helps avoid misdiagnosis.展开更多

In this study, we performed a retrospective analysis using clinical and pathologic data from 109 nonmetastatic operable male breast cancer patients treated from January 1996 to December 2011 at Tianjin Medical University Cancer Institute and Hospital. Log-rank test showed that lower tumor stage, no lymph node involvement, and positive estrogen/progesterone receptor status were good predictors of both disease-free survival and overall survival on univariate analysis. However, hormonotherapy is only a good predictive factor of disease-free survival, and not of overall survival. In addition, based on a Cox proportional hazard regression model, only lymph node involvement, and estrogen/progesterone receptor status were statistically significant predictive factors on multivariate analysis. Our results demonstrated that although adjuvant systemic therapy is used extensively in male breast cancer patients and prognosis has improved over the last few decades, lymph node involvement, and estrogen/progesterone receptor status are still the most important prognostic factors. A prospective multi-center study with a larger sample size is urgently needed to further understand male breast cancer.展开更多

Here, the pathologic data of larger specimens of this disease are reviewed and analyzed for studying its clinical characteristics in order to provide support information for clinical diagnosis. Methods: To review and study the clinical data of 20 patients of esophageal carcinosarcoma. Results: Most of esophageal carcinosarcoma grew like pileus or polypus in esophagus, a few of them were infiltrating. Microscopic examination of the resected specimens indicated that the tumor is composed of sarcomatous element and carcinomatous element (the main element), and the surface of such tumor was covered mostly by carcinoma tissues. The result of biopsy showed that the tumor is squamous cell carcinoma. X-ray examination indicated that there was polypus-like smooth and tidy filling defect in the esophagus of such patient, and its mucous membrane showed “daubing-trace” like characteristics. Conclusion: Carcinosarcoma of esophagus is a tumor of low invasion, which grows mainly in the esophageal lumen. The clinical symptoms of this tumor are different from those of esophagus carcinoma in certain degree. The “daubing-trace” like characteristics is typical of X-ray picture. The results of most endoscopic biopsies demonstrate squamous cell carcinoma or lower differentiation carcinoma, which are difficult for confirmed diagnosis before operation.展开更多

文摘AIM:To explore the methylation status of MSH6 in retinoblastoma(RB)and its impact on clinicopathological features and diagnosis.METHODS:Differentially expressed genes were identified through bioinformatics screening of the GSE24673 and GSE125903 datasets,combined with GeneCards database analysis.A total of 102 RB patients and 62 traumaenucleated controls between January 2018 and December 2023 were enrolled,with their clinicopathological data and retinal tissues collected.The mRNA and methylation levels of MSH6 in retinal tissues were detected using real-time quantitative polymerase chain reaction(PCR)and methylation-specific PCR.Western blot analysis was conducted in one pair of RB and control tissues for preliminary protein-level validation of MSH6 expression.Based on the methylation status of MSH6,RB patients were categorized into two groups:low-methylation and highmethylation.Both univariate and multivariate analyses were conducted to identify independent factors influencing the methylation levels using clinicopathological data.Receiver operating characteristic(ROC)curves were applied to evaluate the diagnostic potential of MSH6 methylation in RB.RESULTS:Bioinformatics analysis of public datasets revealed that MSH6 expression was downregulated across multiple cancers,RB.Consistently,in clinical RB tissues,MSH6 mRNA expression was significantly lower than that in control retinal tissues,whereas the promoter methylation level of MSH6 was markedly higher(both P<0.001),indicating that promoter hypermethylation may contribute to transcriptional silencing of MSH6 in RB.Patients with higher MSH6 methylation levels showed more advanced pathological classification and a higher frequency of metastasis.Multivariate logistic regression confirmed that metastatic status(P=0.008,OR=3.51)and pathological classification(P=0.005,OR=3.7)were independent factors associated with MSH6 methylation.Receiver operating characteristic(ROC)analysis demonstrated that MSH6 methylation could effectively distinguish RB tissues from non-tumorous controls(AUC=0.847,sensitivity=78.43%,specificity=80.65%),suggesting that MSH6 hypermethylation may serve as a potential diagnostic biomarker for RB.CONCLUSION:The methylation level of the MSH6 gene may be a key factor in RB pathogenesis.The methylation status of the MSH6 gene is closely associated with clinicopathological features and shows diagnostic potential.
文摘Objective:To enhance the reading skills of clinical pathology residents,it is essential to establish a well-structured electronic pathology reading library.Methods:In accordance with the Resident Standardization Training Content and Standards(2022 Edition),clinical pathology residents are required to master pathological diagnoses across 11 systems:skin,head and neck,mediastinum and respiratory,digestive,urinary and male reproductive,female reproductive and breast,lymphatic and hematopoietic,bone and soft tissue,cardiovascular,central nervous,and endocrine diseases.Senior pathologists specializing in each subspecialty selected classic pathological slides,which were systematically scanned and compiled into an electronic pathology library.Results:A questionnaire survey was conducted to gather feedback on the electronic pathology reading library.Residents generally found it to be convenient,efficient,and conducive to learning.Conclusion:Training in clinical pathology diagnosis is a core component of standardized resident training.The electronic pathology reading library has been well-received and recognized by resident doctors.However,further efforts are needed to explore diverse teaching methods that align with modern educational approaches,ultimately contributing to the development of highly skilled resident doctors.

文摘BACKGROUND Colorectal cancer(CRC)during pregnancy poses significant risks to both maternal and fetal health;however,this topic remains under researched globally.AIM To investigate the impacts of clinical features,pathology type,treatment strategies,and tumor stage on maternal and fetal outcomes in pregnant patients with pregnancy-associated CRC(pCRC).METHODS To address this research gap,we analyzed the clinical and pathological characteristics of pCRC by collecting and evaluating clinicopathological data from 43 patients treated at the National Cancer Center/Cancer Hospital,Chinese Academy of Medical Sciences,between 1999 and 2023 using descriptive statistical methods.RESULTS Treatment for pCRC was initiated with surgery and/or chemotherapy.Among 43 patients,37 underwent surgery,including 21 radical resections(5 prenatal and 16 postpartum resections)and 16 palliative surgeries.Chemotherapy(with regimens such as CapeOx or FOLFOX4)was administered to 37 patients.Six advanced-stage patients received chemotherapy alone.The gestational outcomes among the patients varied.Specifically,5 patients who were diagnosed in early pregnancy chose abortion.Additionally,in mid-pregnancy,3 patients underwent abortion,1 required induced labor,and 2 underwent cesarean delivery with healthy neonates.Among the 3 late-pregnancy diagnoses,1 patient underwent induced abortion,1 delivered via cesarean section with a healthy fetus,and 1 underwent stillbirth management.The 5-year survival rate was 59.8%,with a rate of 100%for stage I/II patients,75%for stage III patients,and 21.1%for stage IV patients.CONCLUSION Patients with poorly differentiated tumors exhibited worse outcomes than those with moderately and highly differentiated tumors.Early-stage diagnosis and timely treatment significantly improved maternal survival and fetal outcomes in pregnant patients with CRC.Advanced tumor stages and delayed diagnosis were observed to be associated with poorer maternal prognoses and may require interventions that compromise fetal survival.Fetal outcomes depend on the pathological stage of the mother’s cancer,the gestational age at diagnosis,and treatment strategies.

文摘AIM:To investigate the clinicopathological features of cranial-nasal-orbital communicating lesions and identify key diagnostic indicators for differentiating benign and malignant neoplasms.METHODS:The retrospective cohort study analyzed 74 histologically confirmed cases stratified by anatomical involvement at the Wuhan Union Hospital between January 2010 and December 2020:Group A(orbital-nasal group,n=29),Group B(orbital-cranial group,n=27),and Group C(cranial-nasal-orbital group,n=18).Clinicopathological profiles including symptom presentation,histopathology,and invasion patterns were systematically evaluated.RESULTS:The cohort comprised 49(66.2%)benign and 25(33.8%)malignant lesions.Compared with benign lesions,malignant lesions had a shorter onset time(12mo vs 2.5mo,P=0.004)and resulted in poorer vision(0.6 vs 1.53,P=0.025).Headache was reported in 28.6%of patients with benign lesions,but none in those with malignant lesions(P=0.002).Conjunctival congestion and edema were observed in 32.7%of patients with benign lesions and 60%of patients with malignant lesions(P=0.028).The ethmoid sinus was the most frequently invaded site(35 cases).Malignant lesions showed greater invasion in the nasal cavity(28.0%vs 0,P=0.000)and anterior cranial fossa(40.0%vs 8.2%,P=0.003)than benign lesions.The orbital-cranial group was more likely to invade through osseous foramina compared with the orbitalnasal group(P=0.002).Neurogenic tumors predominated benign cases(34.7%),whereas blood derived(28%)and glandular tumors(28%)were most prevalent in malignant subgroups.The proportion of malignant tumors in multidisciplinary combined surgery was higher than that of benign lesions(61.5%vs 38.5%).CONCLUSION:Malignant cranial-nasal-orbital communicating lesions exhibit distinct clinicopathological signatures characterized by rapid progression,aggressive anterior fossa and nasal region,and severe visual morbidity.
文摘BACKGROUND Gastric cancer ranks among the leading malignancies worldwide,noted for its high morbidity and mortality,and remains a significant challenge to global public health.AIM To investigate the association between the expression of splicing factor 3b subunit 4(SF3B4)and high mobility group box 1(HMGB1)with the clinical characteristics and prognostic outcomes of gastric cancer patients.METHODS A retrospective cohort study was conducted involving 114 individuals diagnosed with gastric cancer and admitted to our institution from January 2020 to December 2021.A comparison group of 90 patients diagnosed with benign gastric disorders during the same period was also included.Expression levels of SF3B4 and HMGB1 were assessed using real-time quantitative polymerase chain reaction.Expression patterns were analyzed in relation to various clinicopathological features.Receiver operating characteristic curves were constructed to evaluate the ability of SF3B4 and HMGB1,alone and in combination,to predict unfavorable one-year outcomes.Multivariate logistic regression was utilized to identify independent predictors of mortality.Kaplan-Meier survival curves were generated to examine survival differences based on SF3B4 and HMGB1 expression levels.RESULTS Both SF3B4 and HMGB1 were markedly upregulated in tumor tissues of gastric cancer patients compared to adjacent normal tissues and to tissues from nonmalignant gastric disease patients(^(a)P<0.05).Higher expression levels of these two genes were significantly associated with aggressive pathological features,including poor differentiation,tumor size>5 cm,deep infiltration(T3-T4),lymph node involvement,and advanced clinical stage(III–IV)(^(a)P<0.05).Receiver operating characteristic analysis revealed that the combined use of SF3B4 and HMGB1 yielded an area under the curve of 0.914,surpassing the predictive performance of either marker alone(SF3B4:0.776;HMGB1:0.757).Multivariate analysis identified SF3B4≥1.45,HMGB1≥0.93,poor differentiation,larger tumor size,deeper invasion,lymph node metastasis,and advanced clinical tumor-node-metastasis staging as independent factors contributing to one-year mortality(^(a)P<0.05).Survival analysis indicated that patients with elevated SF3B4 and HMGB1 levels had a shorter median survival(25.74±5.46 months)compared to those with lower expression levels(33.29±6.71 months,log-rank=10.534,^(a)P<0.05).CONCLUSION Elevated SF3B4 and HMGB1 expression in gastric cancer tissue is significantly associated with tumor aggressiveness,worse prognosis,and reduced survival.These biomarkers may offer clinical value in stratifying patients by risk and in forecasting outcomes.Their combined assessment improves predictive accuracy for poor prognosis and may serve as a more effective tool than individual evaluation.

文摘BACKGROUND Mucosal adenocarcinoma of the descending duodenum is a very rare gastroin-testinal tumor.Due to its low incidence,it has rarely been the focus of clinical and pathological studies.The clinical manifestations of these tumors are usually nonspecific,and they are easily misdiagnosed or missed.Pathological diagnosis is the gold standard for diagnosis,but due to the small number of cases,the relevant pathological characteristics and diagnostic criteria are not completely clear.The purpose of this study was to deepen the understanding of the diagnosis and treatment of this disease and to provide a clinical guidance.CASE SUMMARY A 61-year-old woman who was hospitalized with recurrent abdominal pain for more than 20 days.The patient developed epigastric pain with no obvious cause more than 20 days prior,mainly left epigastric pain and middle epigastric pain,and presented persistent dull pain without nausea or vomiting,fever or chills.The patient was treated at a local hospital,gastroscopy revealed a new lesion in the circum-intestinal cavity in the descending part of the duodenum,and pathological biopsy revealed mucous adenocarcinoma in the descending part of the duode-num.Currently,for further diagnosis and treatment,the patient is admitted to our hospital for surgical treatment for“malignant tumor of the duodenum”in the outpatient department.CONCLUSION Mucosal adenocarcinoma of the descending duodenum has a high misdiagnosis rate and missed diagnosis rate,clinical manifestations lack specificity,and pathological diagnosis is the main basis for diagnosis.
文摘To systematically assess the clinical efficacy of Salvia miltiorrhiza(SM)in treating pathological scars and provide a reference basis for scar pharmacotherapy,we conducted a comprehensive literature search in both English and Chinese databases from database inception to December 2022.Key search terms included Salvia miltiorhiza,cryptotanshinone,tanshinone IIA,sodium-tanshinol,compound Salvia miltiorrhiza dripping pills,cicatrix,cicatrices,and scar.The inclusion criteria encompassed all clinical randomized controlled studies on the treatment of pathological scars with SM,without regard to blinding or allocation concealment,as well as irrespective of patient nationality,race,or age.Data from the selected literature were subjected to analysis using Rev Man 5.4 software,employing the standard mean difference or weighted mean difference for numerical variables and odds ratios(ORs)for dichotomous variables.Statistical significance was set at P<0.05.Six eligible studies involving a total of 778 patients met the inclusion criteria.The analysis revealed a significant therapeutic efficacy with an OR of 3.83(95%CI:2.65–5.54),indicating a substantially higher therapeutic efficacy rate in SM group compared to the control group.Furthermore,the total effective rate of treatment exhibited an OR of 6.94(95%CI:2.53–19.06),signifying a significantly superior treatment outcome in SM group.Regarding scar scores,no significant improvement was observed in SM group compared to the control group after 3 months of treatment(mean difference[MD]=–0.96,95%CI:–2.29–0.36).However,after 6 months of treatment,the scar score demonstrated a noteworthy improvement in SM group(MD=–1.37,95%CI:–2.44 to–0.30)compared to the control group.In summary,this study affirmed that SM treatment markedly enhanced the therapeutic efficacy and overall treatment efficiency for clinical scar patients,underscoring its positive clinical therapeutic impact on scar patients.
文摘Background: Dermatofibroma usually occurs on the extremities or trunk as a common and benign skin tumor. The identification of typical dermatofibroma is uncomplicated, although it can be challenge due to its wide range of presentations and histological variations. Objective: This study was undertaken to evaluate the clinical and histopathological characteristics of 147 Cases of Dermatofibroma. Methods: This is a retrospective study of 147 biopsy specimens of 124 patients who were diagnosed with dermatofibroma in the Department of Dermatology and the Department of Pathology at the Seventh Affiliated Hospital of Sun Yat-sen University between January 2009 and April 2024. All case were retrieved from the saved medical records. Results: Ages of the 124 Dermatofibroma-affected individuals ranged from 11 to 61 years with a male-to-female ratio of 1:1.7. Over 80% of the case occurred between the ages of 20 and 49 years, 61.9% of the lesions were found on the extremities. The duration of the cases varied from 17 days to 30 years and half of lesions (58.2%) persisted for less than two years. Over 60% of the lesions were found on the extremities. The diameter of the tumors ranged between 0.3 cm and 5 cm, with most tumors measuring less than or equal to 2 cm (85.00%). Cutaneous masses or dermatofibroma was the most common clinical diagnosis. Most tumors (79.6%) were asymptomatic. Cutaneous masses or dermatofibroma was the most common clinical diagnosis. Prior to the surgical procedure, 57 cases were suspected to be “DF”, 55 cases were suspected to be “cutaneous masses”. Immunohistochemical staining revealed positive expression of SMA, while the negative rate of CD34 was found to be 66.67%. No diffuse CD34 positivity was observed in all tumors. Conclusion: Variations in clinical features, pathological manifestations, and immunohistochemical results of DF pose challenges for accurate diagnosis. A comprehensive understanding of its clinical and pathological characteristics is crucial for precise identification. Incorporating immunohistochemical analysis can help prevent misdiagnosis.
文摘Background: Neurilemmoma (Schwannomas) are the most common peripheral nerve tumors and usually do not undergo malignant transformation, except in some atypical cases. Additionally, the imaging appearance of schwannomas resembles that of neurofibromas, making it difficult to distinguish between the two. Therefore, the clinical diagnosis and treatment of schwannomas may face certain challenges. The management and prognosis of neurilemmomas differ from their malignant counterparts, making correct diagnosis important. Objective: This study evaluates the clinical and histopathological characteristics of 45 cases of neurilemmoma. Methods: This retrospective study involves 45 cases diagnosed with cutaneous neurilemmoma at the Seventh Affiliated Hospital of Sun Yat-sen University between April 2020 and September 2024. All cases were retrieved from medical records. Results: The age range of the 45 patients was 23 to 73 years, with a male to female ratio of 1.6:1. Over half the cases occurred in individuals aged 30 to 59, with most lesions found in the extremities, predominantly in the lower limbs. Disease duration varied from 7 days to 20 years. All tumors were solitary, with diameters ranging from 0.8 cm to 8 cm. Most tumors (33/45, 73.33%) were asymptomatic, though some patients experienced symptoms like pain and numbness. Mass was the most common clinical diagnosis (33/45, 73.33%). Five patients had suspected neurilemmomas prior to surgery. Immunohistochemical staining revealed all positive results for S-100 and SOX-10 markers, while EMA staining showed a negative rate of 93.33%. Most Ki-67 values (19/23, 82.6%) were less than or equal to 5%. Conclusion: The diversity of clinical features, pathological manifestations, and immunohistochemical results of schwannoma poses a challenge to accurate diagnosis. A comprehensive understanding of its clinical and pathological characteristics is essential for accurate diagnosis, and when combined with immunohistochemical analysis, it helps avoid misdiagnosis.

文摘Compared with female breast cancer, male breast cancer is a rare disease, and the relationship between clinical/pathologic features and prognosis is controversial, or even largely unknown. In this study, we performed a retrospective analysis using clinical and pathologic data from 109 nonmetastatic operable male breast cancer patients treated from January 1996 to December 2011 at Tianjin Medical University Cancer Institute and Hospital. Log-rank test showed that lower tumor stage, no lymph node involvement, and positive estrogen/progesterone receptor status were good predictors of both disease-free survival and overall survival on univariate analysis. However, hormonotherapy is only a good predictive factor of disease-free survival, and not of overall survival. In addition, based on a Cox proportional hazard regression model, only lymph node involvement, and estrogen/progesterone receptor status were statistically significant predictive factors on multivariate analysis. Our results demonstrated that although adjuvant systemic therapy is used extensively in male breast cancer patients and prognosis has improved over the last few decades, lymph node involvement, and estrogen/progesterone receptor status are still the most important prognostic factors. A prospective multi-center study with a larger sample size is urgently needed to further understand male breast cancer.
文摘Objective:Carcinosarcoma of esophagus is an infrequent disease. Here, the pathologic data of larger specimens of this disease are reviewed and analyzed for studying its clinical characteristics in order to provide support information for clinical diagnosis. Methods: To review and study the clinical data of 20 patients of esophageal carcinosarcoma. Results: Most of esophageal carcinosarcoma grew like pileus or polypus in esophagus, a few of them were infiltrating. Microscopic examination of the resected specimens indicated that the tumor is composed of sarcomatous element and carcinomatous element (the main element), and the surface of such tumor was covered mostly by carcinoma tissues. The result of biopsy showed that the tumor is squamous cell carcinoma. X-ray examination indicated that there was polypus-like smooth and tidy filling defect in the esophagus of such patient, and its mucous membrane showed “daubing-trace” like characteristics. Conclusion: Carcinosarcoma of esophagus is a tumor of low invasion, which grows mainly in the esophageal lumen. The clinical symptoms of this tumor are different from those of esophagus carcinoma in certain degree. The “daubing-trace” like characteristics is typical of X-ray picture. The results of most endoscopic biopsies demonstrate squamous cell carcinoma or lower differentiation carcinoma, which are difficult for confirmed diagnosis before operation.
