Trends and Histopathological Patterns of Kaposi Sarcoma at The University of Benin Teaching Hospital, Benin City, Nigeria

Kaposi sarcoma (KS) shows greater geographic variation in incidence than almost any other vascular tumor globally. KS is common in parts of Sub-Saharan Africa accounting for 9% of all diagnosed cancer cases in men in the early 1990’s in Uganda and Zaire. KS is classified by the World Health Organization as a borderline vascular tumor. We aimed to determine the trends and histopathological patterns of KS as seen in the University of Benin Teaching Hospital in Benin City, Nigeria, and to compare with similar work in other centers
