Primary adrenal angiosarcoma]

Primary angiosarcomas of the adrenal gland are extremely rare neoplasms, first described in 1988. We report the twentieth case, incidentally discovered in a 60 year-old male. The main histological features were epithelioid appearance and immunohistochemical co-expression of endothelial markers and cytokeratin by neoplastic cells. The potential diagnostic pitfalls of these morphological characteristics are discussed. The patient underwent surgery and adjuvant chemotherapy and is free of tumour recurrence three years after surgery.
