A 40-year-old male has had increasing cough with hemoptysis for 2 weeks. He is febrile, and a chest radio- graph shows a right upper lobe area of consolidation that improves with antibiotic therapy. However, his cough and the hemoptysis persist. Bronchoscopy reveals an obstruct- ing mass filling the bronchus to the right upper lobe. Which of the following neoplasms is most likely to pro- duce these findings? O (A) Hamartoma O (B) Adenocarcinoma O (C) Large cell carcinoma O (D) Kaposi sarcoma O (E) Carcinoid tumor

The answer is (E)Most pulmonary carcinoids are central, obstruct- ing masses involving a bronchus. They are neuroendocrine tumors with a somewhat unpredictable behavior, although many are resectable and follow a benign course. They typically present with hemoptysis and consequences of bronchial obstruction. In this case, the pneumonia in the right upper lobe probably resulted from obstruction to drainage caused by the tumor. Adenocarcinomas are com- mon lung tumors but are typically peripheral. A hamartoma is an uncommon but benign pulmonary lesion that is also located peripherally. Large cell carcinomas are typically large, bulky, peripheral masses. Kaposi sarcoma can be seen involving the lung in some patients with AIDS, and the tumor often has a bronchovascular distribution, but obstruction is uncommon.
