Primary Malignant Fibrous Histiocytoma (MFH-T) and Leiomyosarcoma (LMS-T) of the thyroid gland are extremely rare tumors. Very few cases have been reported in the literature. Both entities occur more commonly in women than men. The closest clinical and histological differential diagnosis is anaplastic carcinoma of thyroid. We present three cases of rare primary sarcomas of thyroid gland. Case-1 was a 63-year-old woman and Case-2 was a 52-year-old woman. Both of them presented with a rapidly increasing thyroid mass clinically mimicking anaplastic carcinoma (AC-T). Both the patients developed pulmonary metastasis and succumbed to the illness soon after the diagnosis of MFH-T was made. Case 3 was 65-year-old woman with neck swelling since six months diagnosed as LMS-T. The present communication adds three new cases to the literature on sarcomas of thyroid gland with an emphasis on differential diagnosis of spindle cell lesions of thyroid. MFH-T and LMS-T needs to be differentiated from AC-T, metastatic sarcomas, spindle cell variant of medullary carcinoma, synovial sarcoma, fibrosarcoma; final diagnosis rests on histopathology and immunohistochemistry.
