Kaposi Sarcoma

Kaposi sarcoma is a virally induced, low-grade angiosarcoma. It was initially described in 1872 and subsequently categorized into 4 clinicopathologic subtypes: classic/sporadic, endemic (African), epidemic (AIDS associated), and immunosuppressanttherapy associated. Lesions typically progress from patches to plaques and finally to a nodular stage. Histologic findings vary depending on the stage.
