Kaposi's sarcoma skin lesion

A Kaposi's sarcoma skin lesion is a primary cutaneous manifestation of Kaposi sarcoma, a multifocal angioproliferative neoplasm driven by infection with human herpesvirus 8 (HHV-8/KSHV) Pathophysiologically, they are characterized by aberrant angiogenesis, spindle-shaped endothelial cell proliferation, extravasated erythrocytes, and intracellular or interstitial hemosiderin deposition

A Kaposi's sarcoma skin lesion is a primary cutaneous manifestation of Kaposi sarcoma, a multifocal angioproliferative neoplasm driven by infection with human herpesvirus 8 (HHV-8/KSHV) Clinically, these lesions present as solitary or multiple non-blanching macules, patches, plaques, or nodular tumors that are typically red, purple, brown, or violaceous

It primarily impacts the integumentary system, most commonly arising in immunocompromised populations—such as individuals with advanced HIV infection or organ transplant recipients—as well as older Mediterranean or Eastern European men and endemic populations in Africa
