Spindle cell sarcoma of thyroid: a case report.

Spindle cell sarcoma of thyroid represents a rare entity that may arise primarily from thyroid gland as a variant of thyroid cancer or as metastatic. We report a case of 60 year old man who presented with 2 months history of rapidly growing thyroid enlargement with no obstructive features and preliminary diagnosis of spindle cell lesion of thyroid was made with cytological examination. He underwent total thyroidectomy and histological examination revealed spindle cell sarcoma of thyroid confirmed by immunohistochemical reactions. He was subjected to adjuvant chemoradiotherapy and is on follow up. Sarcoma of thyroid is rarely encountered in routine practice and is diagnosed by microscopic evaluation and immunohistochemical staining which determines the cellular origin and histologic type of tumor . Sarcoma thyroid is best managed with surgery and adjuvant chemoradiotherapy according to the grade of the lesion. In addition overall prognosis in thyroid sarcoma is poor due to late presentation and aggressive nature of the tumour.
