Kaposi Sarcoma of the Nail Unit: A Case Report and Review of the Literature.

Introduction:Kaposi sarcoma is an angioproliferative neoplasm. Its manifestations are well known but nail involvement seems extremely underreported. Case Presentation:A 55-year-old man presented with a 6-month history of a growing subungual tumor affecting the third right toe. After surgical excision, histological examination revealed a Kaposi sarcoma. Discussion:We report a case of Kaposi sarcoma with nail involvement of only one toe as the first and unique manifestation, which is exceptional.
