[Coincidence of Pneumocystis carinii pneumonia and lung carcinoma in AIDS].

In a formerly drug-dependent patient of 35 years of age suffering from an advanced HIV infection there was a development within a period of a few months of rapid weight loss amounting to 12 kg, persistent subfebrile temperatures and progressive dyspnoea on exercise. The histological pattern obtained via bronchoscopy revealed not only pneumocystis carinii pneumonia, which had already been suspected clinically, but also a not very differentiated adenocarcinoma of the lung with lymphangiosis carcinomatosa. The patient died three months after tis diagnosis was established, which had been followed by the usual pneumocystosis therapy and palliative treatment with glucocorticoids.
