Kaposi's sarcoma, a major complication in homosexual or bisexual acquired immunodeficiency syndrome (AIDS) patients, is a ubiquitous disease marked by cutaneous tumor and lymphadenopathy in the dermal and visceral organs. Cutaneous and gastrointestinal tract Kaposi's sarcoma is common, but respiratory system involvement is rare. This report describes a young male AIDS patient suffering from endobrochial Kaposi's sarcoma without cutaneous involvement. Multiple solid endobronchial tumors were characterized by a glinting surface under bronchoscopy. The endobronchial nodules regressed after 3 months of treatment with highly active antiretroviral therapy, including Combivir (Lamivudine 150 mg + Zidovudine 300 mg) twice a day, Lopinavir 800 mg per day and Ritonavir 200 mg per day. The possibility of endobronchial Kaposi's sarcoma should be considered in HIV patients suffering from chronic cough beyond opportunistic infection.
