title: A novel variety of atypical Pneumocystis carinii infection after long-term prophylactic pentamidine inhalation in an AIDS patient: large lower lobe pneumocystoma.
abstract: Atypical pulmonary manifestations of Pneumocystis carinii infection and fair numbers of extrapulmonary and disseminated infections have lately been documented in patients with human immunodeficiency virus infection treated prophylactically with inhalative pentamidine. We report the case of a 32-year-old homosexual patient who was assessed for complaints of night sweats, weight loss, and progressive malaise. The patient denied any respiratory tract symptoms such as cough, sputum production, pleuritic chest pain, or shortness of breath. Chest X-ray revealed two large round noncavitating lesions in the lower lobe of the right lung. Pneumocystomas were diagnosed by fine-needle aspiration. A 3-week course of intravenous high-dose cotrimoxazole resulted in amelioration of symptoms but no change in the radiographic appearance of the pulmonary lesions. Four months later the patient is alive and stable and is being treated with pentamidine inhalation of 300 mg per 2 weeks and two tablets of pyrimethamine sulfadoxine per week.
