Endemic Kaposi's Sarcoma.

Kaposi's sarcoma (KS) is a common neoplasm in Eastern and central Africa reflecting the spread of 8 (HHV-8), now considered a necessary causal agent for the development of KS. The endemic KS subtype can follow an aggressive clinical course with ulcerative skin lesions with soft tissue invasion or even bone or visceral involvement. In the latter cases, a thorough imaging work-up and better follow-up schedules are warranted.
