Kaposi's sarcoma (KS) is an unusual neoplasm that has proved to be an enigma in many ways since its original description in 1872. KS, a vascular tumour that is otherwise rare, is at present the most common neoplasm in patients with AIDS. The lesions contain spindle cells that share features with endothelial cells and smooth muscle cells and are in all likelihood primitive mesenchymal cells that can form vascular channels. These cells are monoclonal in origin indicating therefore that KS is a neoplasm. The presence of a novel type of human herpes virus, KS herpesvirus (KSHV) also called human herpesvirus type 8 (HHV8) in KS lesions support a viral ethiology. KS may be mistaken in the skin for an inflammatory or other lesion, thus skin biopsy is important for correct diagnosis, with the use of immunohistochemistry or molecular biology if needed. Radiation or interferon alpha dominate in the therapeutic approaches.
