Fine-needle cytology of Kaposi's sarcoma in an intramammary lymphnode: report of one case.

Kaposi's sarcoma (KS) is the most common human immunodeficiency virus (HIV) infection disease-associated malignancy. It consists of an angiosarcomatous change of the epithelial and mucous membrane-associated connective tissue not only in various sites, for example, skin, gastrointestinal system, lungs, and so on, but may also involve nonepithelial organs, such as lymph nodes. An unusual localization of KS to an intramammary lymphnode is reported here. The patient, an HIV-negative 69-year-old woman with a clinical history of rheumatoid arthritis treated with hydrocortisone, had an 8-month pathological history of biopsy-proven Kaposi sarcoma of the skin with visceral extension (stomach and duodenum). The appearance of a well-defined 23 × 20 mm(2) breast nodule during chemotherapy elicited fine-needle cytology to exclude breast carcinoma. Surgical excision confirmed the cytopathological diagnosis of Kaposis's sarcoma.
