A Case of a Rare Histologic Variant: Cavernous Hemangioma-Like Kaposi Sarcoma.
The American Journal of dermatopathology(2022)
摘要
ABSTRACT:Kaposi sarcoma (KS) is an endothelial tumor associated with human herpesvirus 8. Cutaneous lesions can present with pink or purple patches, plaques, and nodules which can be ulcerated. The main subtypes of KS generally have similar histologic appearances, with spindle cells and expression of human herpesvirus 8 being characteristic features. However, various histologic variants have been reported. We present the case of a 55-year-old man with cutaneous KS with cavernous hemangioma-like histological features. Cavernous hemangioma-like KS is a rare morphologic type of KS, with only a handful of cases reported in the literature.
