title: [Rapidly evolving pulmonary bullous degeneration in HIV-infected patients. Description of 4 cases and review of the literature].
abstract: Cavitary lung lesions are common in intravenous drug-addicts (IVDA) and in AIDS patients. Four cases are reported of IVDA patients with HIV positive serology who developed an initially thick-walled lesion, which grew rapidly and evolved into bullous lesions. The negative results in microbiological investigations for Pneumocystis carinii, Nocardia spp., staphylococci; the topographic superposition on a previous tuberculous lesion; a prolonged asymptomatic period; and a particularly rapid evolution in all cases led us to consider the rapidly evolving bullous degeneration to be more than a casual finding. Previous infection with M. tuberculosis in AIDS patients might somehow influence on the later development of a rapidly growing, fatal, bullous degenerative lesion. The elucidation of the pathogenic mechanisms of these lesions was hampered by the lack of pathological studies.
