We describe the case of a patient with a rapidly growing, nodule in the right breast. On ultrasonography, the nodule was suspicious for breast carcinoma. Case presentation: A breast biopsy from a 73-year-old Moroccan women answered invasive ductal carcinoma grade 3 from Elston and Ellis. Patey was performed. Microscopic examination showed lymphoid proliferation confirmed on immunohistochemical analysis. Our patient was treated with chemotherapy. Conclusions: The rarity of breast lymphomas, and the problems related to the diagnosis and therapeutic choices with these tumors require molecular techniques in association with classical histological diagnosis.展开更多

Signet-ring cell carcinoma of the ampulla of Vater is extremely uncommon and a very rare clinical entity, which is infrequently reported in medical literature and only 31 cases have been mentioned. Most tumors affecting Vater’s Ampulla are adenocarcinomas and other histological variants are less frequent. It mainly occurs in elderly patients. Case Presentation: We report a case of signet ring cell carcinoma of Vater’s Ampulla. The tumour had infiltrated the duodenal, but local lymph nodes were clear (T3N0M0). Duodenopancreatectomy with pylorus preservation is the treatment of choice. Conclusions: Etiology and survival are not well-defined in the literature due to the extreme rarity of this disease.展开更多

No clinical, no radiological, no biological signs are specific to malignant transformation. Case presentation: A 51-year-old woman had a left ovarian tumor measuring approximately 18 cm diameter with malignant transformation of a mature cysticteratoma, who was diagnosed postoperatively with follicular variant of papillary thyroid carcinoma. A laparoscopic hysterectomy and left salpingo-oophorectomy were performed. During surgery, there were no signs of invasion or metastasis. Conclusion: Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radio ablation if residual disease is identified.展开更多
