RESUMO
BACKGROUND: Kaposi sarcoma is an vascular neoplasm caused by infection with human herpesvirus-8. Known risk groups are Mediterranean, eastern European Jewish and African ancestry men or men with AIDS. Nowadays we distinguish more subgroups. CASE DESCRIPTION: We present a healthy 39 year old man with a lesion on the right foot, having homosexual contacts, without HIV infection. Previous histology revealed signs of hemangioma. Recent clinical signs and histology confirmed multifocal Kaposi sarcoma. He was treated with radiotherapy. We also present a 65 year old MSM with and a lesion on the sole of the foot. Histology revealed for a solitary nodular Kaposi sarcoma. A short term relapse after surgical excision occurred. CONCLUSION: Kaposi sarcoma is subdivided into different categories. Kaposi Sarcoma in HIV-negative MSM is seen more frequently today, yet usually shows an indolent course. An adjusted less aggressive treatment and follow-up is therefore justified.
