Pulmonary Kaposi's sarcoma-an atypical clinical presentation

Abstract

HIV-associated Kaposi's sarcoma is an angioproliferative neoplasia caused by infection with human herpesvirus 8. It typically presents with mucocutaneous involvement. Pulmonary Kaposi's sarcoma is rare, and an uncommon form of initial presentation of the disease. The authors present the clinical case of an HIV-positive patient with Kaposi's sarcoma who had exclusively pulmonary involvement at diagnosis. This case is highlighted for its rarity, by the diagnostic challenge it presented, and for the important role of bronchoscopy as a diagnostic tool for this pathology. Bronchoscopy allows direct visualization of the lesions and the ability to perform a bronchoalveolar lavage and directed biopsies.
