Diffuse Kaposi sarcoma with oral involvement in a person diagnosed with human immunodeficiency virus/acquired immune deficiency syndrome: A case report.

Kaposi's sarcoma is a well-known multifocal vascular tumor initially described by pathologist Moritz Kaposi. This report presents the case of a 38-year-old bisexual male who consulted the infectious diseases department with non-itchy maculopapular and purpuric lesions on the skin with the involvement of the oral mucosa, suggesting a diagnosis of Kaposi's sarcoma. Biological and radiological investigations were performed. The patient was found to be human immunodeficiency virus positive with a viral load of 251.000/mL and a CD4 count of 182/mm3. In addition, secondary syphilis was diagnosed. Histopathological examinations confirmed HHV-8 KS. The patient was treated with Extencilline® and antiretroviral therapy. After 10 months of chemotherapy, a favorable outcome was noted with complete resolution of skin and oral mucosa lesions.
