title: Insular carcinoma of thyroid--a case report.
abstract: Insular carcinoma of thyroid (ICT) is a rare tumor, which accounts for 4-6% of thyroid malignancies. ICT arising from follicular cells of thyroid shows a characteristic insular growth pattern characterized by solid nests of tumor cells separated by vessels. A 52-year-old female presented with a huge swelling in midline of the neck with retrosternal extension. The patient was euthyroid. Near total thyroidectomy was done. Grossly, the tumour was involving both the lobes and isthmus of thyroid. Microscopic examination revealed features of insular carcinoma. On immunohistochemistry, tumour cells were positive for thyroglobulin and negative for calcitonin.
