Medical College associated SMHS Hospital Srinagar in the first decade of this century are presented. Age of the patients ranged from 17 to 68 years peaking in the fourth decade of life (Figure 1 and Figure 2). Near 85% of the patients with thyroid masses were female and most of the cases (76%) euthyroid at the time of presentation. Depending upon the expertise of the pathologist, the FNA cytology has a good role in the preoperative diagnosis of thyroid masses especially the malignant types (Figure 3 and Figure 4). The specificity of FNA cytology in detecting malignant thyroid tumors in this study was 100% and the sensitivity was 73.08%. The overall diagnostic accuracy was 83.20%. 45.60% of the thyroid masses proved on excision biopsy to be malignant of which papillary carcinoma continued to be the most common malignant thyroid tumor followed by the medullary, the follicular and the undifferentiated types. Radionuclide scanning gave equivocal results in distinguishing between the benign and the malignant thyroid nodules in this study, but it was useful in evaluating indeterminate cases of FNA cytology. Magnetic resonance imaging of neck was used as an adjunctive imaging modality in assessing the extent of the primary malignant thyroid lesion, its direct extra-thyroidal spread and regional nodal metastases (Figure 5 and Figure 6). Different surgical techniques utilized in dealing with the thyroid masses included partial thyroidectomies and total thyroidectomy with or without modified neck dissection and the results are discussed.展开更多

Thyroid metastasis from colorectal cancer(CRC) is rare and has a poor prognosis. We herein report a rare case of solitary thyroid metastasis from rectal cancer combined with needle tract implantation after fine-needle aspiration(FNA) of the thyroid nodule and review the relevant literature.CASE SUMMARY A 54-year-old woman with a history of TNM stage Ⅲ CRC presented a 1.3 cm × 1.0 cm mass in the left thyroid gland. FNA and histological examination of the left thyroid lobe surgical specimen confirmed the diagnosis of isolated metastatic adenocarcinoma from the rectum. Needle tract implantation was observed in the neck 11 mo after the FNA examination. The 2.5-cm seeding lesion was successfully removed by surgery, and the patient recovered well. The literature relevant to this clinical condition, the diagnostic workup, spread pathway, and surgical management of these rare lesions is reviewed.CONCLUSION For a patient with a thyroid mass and a history of CRC, metastatic thyroid carcinoma should be considered even if the patient has no evidence of other organ metastasis from CRC. FNA cytological examination of the thyroid mass is useful in the differential diagnosis between primary thyroid disease and metastatic thyroid carcinoma. Thyroid lobectomy of the gland containing the metastatic tumor is suggested in patients with metastatic carcinoma of the thyroid.展开更多
