Sumario:BACKGROUND: Pulmonary Kaposi's sarcoma (PKS) directly affects the life expectancy of those infected and yet the clinical and radiographic features of Kaposi's sarcoma (KS) with pulmonary involvement are nonspecific, which makes diagnosis difficult. In Uganda, pulmonary tuberculosis, which has clinical features that closely resemble those of PKS, also occurs commonly and thus confusion is bound to arise. Bronchoscopy is a recognized diagnostic investigatory modality for PKS. The aim of present study was to identify unique or useful points for the differential diagnosis of PKS and other opportunistic infections. METHODS: The clinical, radiologic, and bronchoscopic findings in thirty-five Ugandan patients (age 20-50, median 32) with PKS were analyzed. RESULTS: Cough and weight loss were most common and occurred in 97.1%, whereas fever occurred in 62.9%, and breathlessness in 57.1%. Thirty-four patients (97.1%) showed mucocutaneous KS, and palatal KS was most frequent and was observed in 74.3%. In addition, 25 patients (71.4%) showed the characteristic endobronchial plaques of KS. The most frequently observed radiographic abnormality was bilateral reticulonodular density. Histological examinations of bronchoscopic biopsies revealed KS in 7 (36.6%) cases. Five PFS patients (25%) also had co-existent tuberculosis. CONCLUSIONS: The majority of patients with PKS showed no specific findings on physical examination, apart from mucocutaneous KS. Our findings indicate that palatal KS may be a strong predictor of PKS. In Uganda, pulmonary tuberculosis may be the most common concomitant pulmonary infection in PKS patients.
