Abstract: Kaposi sarcoma KS is a rare, angioproliferative disorder primarily associated with human herpesvirus 8 HHV8. This article discusses a case involving a 29 year old man diagnosed with HIV and KS, with unusual colorectal and anal canal involvement but no skin lesions. Despite antiretroviral treatment, the patient experienced clinical deterioration, ultimately leading to a fatal outcome. The case emphasizes the rarity and complexity of KS in the gastrointestinal tract, particularly in the absence of external manifestations, and discusses the clinical and histological challenges in diagnosing and managing such cases.
