Cytodiagnosis Of Follicular Carcinoma Thyroid From Metastatic Sites: A report Of Three Cases

Abstract

Thyroid cancers account for around 0.5% of all cancers in males and 1.5% of all cancers in females. FTC is the second most common cancer of thyroid gland after papillary carcinoma. A common mode of presentation is a solitary thyroid nodule. Reported incidence of distant metastasis is between 11 to 25%, but it is very uncommon for the disease to present with distant metastasis at initial presentation itself [1] FTC commonly metastasizes to lungs, bones, brain, and liver. Skeletal metastasis of FTC are usually multiple and have a predilection for shoulder girdle, sternum, skull and iliac bones. [2] Rarely they can be the only presenting symptom. [1,3] When diagnosed early, FTC with metastatic disease has relatively better prognosis as compared with other forms of metastatic malignancies. [3] We report three cases of metastatic FTC which were diagnosed by FNAC.
