Insular Carcinoma of Thyroid

Abstract

Introduction: Insular carcinoma is a rare tumour with frequent tumour necrosis and micro follicles. Materials and Methods: Female patients with swelling in front of neck, USG and FNAC were carried out. FNAC showing follicular neoplasm were followed up with histopathology and 2 cases are presented here. Observation: Two female cases with swelling in front of neck with cytology depicting follicular neoplasm were studied. Discussion: Insular carcinoma of thyroid arises from follicular epithelium hence have abortive follicles with necrosis. Its prognosis lies between well and poorly differentiated thyroid carcinoma. Conclusion: It is necessary to recognize the tumour for better prognosis.
