Black thyroid discoloration following long-standing use of minocycline has been reported. Morphologic findings of aspiration cytology of these lesions was first reported from The Ohio State University. This abstract describes a second case of black thyroid that was preceded by aspiration cytology. In both cases, thyroidectomies were performed based on "indeterminate" fine-needle aspiration cytology (FNAC). Degenerative changes in follicular epithelial cells in black thyroid causes nuclear hyperchromasia and chromatin clumping, which may be mistaken for neoplasia. Pigment present in follicular epithelial cells and macrophages may be obscured by pigments with similar microscopic appearances, such as hemosiderin. A clinical history of the chronic use of a tetracycline derivative should alert the pathologist to the possibility of black thyroid. Diagnosis may be made by applying special stains on the cell block. The pigment stains with Melanin stain (Fontana) and bleaches with potassium permanganate. In the light of increasing use of FNAC of the thyroid gland and the large number of patients who received tetracycline therapy in the last two decades, it is likely that some practicing cytopathologists may experience this pitfall.

A Hürthle cell tumor of the thyroid gland resected ten days after fine needle aspiration (FNA) showed extensive necrosis accompanied by a small area of hemorrhage. Although no vascular thrombosis was noted in the histologic specimen, it is possible that the necrosis was the result of compromised vascular supply due to the FNA.

Clinical, biopsy and necropsy studies of a homosexual boar revealed angio-proliferative lesions in the skin of the thigh, scrotum and the inguinal lymph node. Angiofibromas were identified in the dermis and subcutis of the thorax and mandible. The avidin-biotin-peroxidase complex technique demonstrated Factor VIII-related antigen as a marker for the neoplastic endothelial cells of the tumors. This boar also showed weight loss and lymphopenia. Explants of tumors were maintained in cultures for 22 passages and cultured cells produced tumors when injected subcutaneously into nude mice. No viral antigen was detected in the cultured tumor cells. Similarities and differences between the lesions in the boar and human Kaposi's sarcoma are discussed.
