Cytopathology of Hürthle cell lesions of the thyroid gland by fine needle aspiration

Abstract

The increasing use of fine needle aspiration biopsy of the thyroid has refocused attention on Hürthle cell lesions. From 2,317 cytologic studies on "cold" nodules, 70 diagnoses of Hürthle cell tumor were made. Of 49 thought to be cytologically benign, 37 were confirmed histologically; 3 others were carcinoma, 5 were autoimmune thyroiditis, and 4 were nodular goiter. Of eight considered to be cytologically malignant, histology confirmed six carcinomas and two benign tumors. Identification of nonneoplastic Hürthle cell lesions required experience. Differentiation of benign and malignant Hürthle cell tumors with a high degree of accuracy is probably not possible cytologically with the present state of our knowledge.

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.

Adenoma, Islet Cell

Islet Cell Adenoma arises in the islet cells, which are insulin producing cells of the pancreas. These tumors can be either malignant or benign. Discover the latest research on Islet Cell Adenoma here.

Carcinoma, Islet Cell

Islet Cell Carcinoma or Pancreatic Neuroendocrine Tumours arises in the hormone producing cells of the pancreas. These tumors can be either malignant or benign. Discover the latest research on Islet Cell Carcinoma here.
