Insular carcinoma of thyroid: A case report.

A histological distinct subset of thyroid carcinoma, which falls between well differentiated and anaplastic carcinoma with respect to cell differentiation and clinical behaviour. It has been categorized as poorly differentiated or insular carcinoma based on its characteristic cell groupings. Insular carcinoma warrants aggressive management with total thyroidectomy followed by radioactive iodine ablation of the residual deposit. We present a case of insular carcinoma, which was diagnosed post operatively based on the histopathological enzyme study.
