BACKGROUND: Kaposi sarcoma (KS) is known to involve the mucocutaneous tissues and the aero-digestive tracts. In acquired immune deficiency syndrome (AIDS) patients, KS has an aggressive course and carries poor prognosis. We present a case of pulmonary KS with osseous metastases as the first presentation of human immunodeficiency virus (HIV) infection in a young male. The lesions impressively decreased in size and numbers following initiation of highly active antiretroviral therapy (HAART).
CASE REPORT: A 34-year-old heterosexual male presented with a one month history of cough and 15–20 pound weight loss within six months. Examination revealed oral thrush, decreased breath sounds and crackles on the right lower lung base. Imaging showed a large right perihilar mass with multiple lytic lesions involving thoracic and lumber vertebrae, ribs, sternum, and clavicles. Blood and sputum cultures, smears for acid fast bacilli, and a QUANTIferon gold test were all negative. He tested positive for HIV and his CD4 count was 7 cells/uL. Bronchoscopy with biopsy was unrevealing. Pathology of the right hilar mass was diagnostic of KS. Following initiation of antiretroviral therapy his condition dramatically improved; repeat chest CT scan showed marked regression of the bony and pulmonary lesions.
CONCLUSIONS: The dual action of HAART on the recovery of the immune system and against human herpes virus 8 (HHV-8) may essentially cause regression of KS lesions.
