Disseminated Kaposi sarcoma presenting in unusual locations: A case report.

Kaposi sarcoma (KS) is the most common malignancy associated with HIV infection. It usually affects the skin, the gastrointestinal tract and the lungs. It is generally described in the setting of CD4 counts < 150 cells/mm - 200 cells/mm. We describe a case of recurrence of KS with a rare presentation of breast and musculoskeletal involvement in the setting of a CD4 count of 374 cell/mm and an undetectable viral load. The patient was on highly active antiretroviral therapy for 5 years at the time of the second presentation.
