De novo anaplastic Kaposi sarcoma in a HIV-negative man: A case report and review of the literature

Abstract

Anaplastic Kaposi sarcoma is a rare variant of Kaposi’s and is typically associated with an agressive clinical course. We report a case of a 67-year-old HIV negative man, presented with multiple, pink nodules on the left ankle and a keratotic lesion of the right heel. Initial histopathological exam concluded to an undifferentiated sarcoma. A second biopsy was performed and concluded to an anaplastic Kaposi sarcoma. Immunohistochemical study was positive for HHV8. Treatment consisted on a tumor excision of all lesions. Our case and the review of the literature highlight the benefit of the non conservative surgical treatment for this aggressive form of Kaposi sarcoma.
