A 46-year-old Italian man seropositive for human immunodeficiency virus (HIV) type 1 was admitted to our department with a 3-month history of nonproductive cough and progressively worsening dyspnea. The patient was a former heroin addict with liver cirrhosis caused by hepatitis C virus and previously treated visceral leishmaniasis and latent syphilis. He was on antiretroviral treatment consisting of emtricitabine, tenofovir, and fosamprenavir with an undetectable HIV load and a CD4 Tlymphocyte count of 180 cells/µL. On hospital admission, the patient was afebrile but short of breath at rest, with a heart rate of 110 beats per minute, respiratory rate of 35 breaths per minute, and oxygen saturation of 80% on room air. Physical examination revealed holoinspiratory wheezing. His oral cavity was unremarkable. Arterial blood gas showed an arterial pH of 7.48, an oxygen partial pressure of 56 mm Hg, and a carbon dioxide partial pressure of 28 mm Hg while breathing ambient air. A computed tomographic scan of the chest was performed showing multiple bilateral pulmonary lesions, some with a cavitary appearance (Figure 1). Bronchoscopy demonstrated tracheal subocclusion caused by irregular, friable rosy vegetations extending over 4 cartilaginous rings (Figure 1C). Biopsies were obtained (Figure 2).
