[Atypical Pulmonary Carcinoid with Multiple Distant Metastases Treated with Primary Tumor Resection]

A 73-year-old man presented with cough and was found to have a tumor in the right lower lobe associated with obstructive pneumonia. Chest computed tomography (CT) and fluorodeoxyglucose positron emission tomography revealed multiple distant metastases involving the liver, lymph nodes, and bone. Bronchoscopic biopsy suggested typical pulmonary carcinoid. Although curative resection was not feasible, primary tumor resection was performed to achieve local control and prevent recurrent obstructive pneumonia. Histopathological examination demonstrated atypical pulmonary carcinoid. The patient subsequently received carboplatin plus etoposide, followed by everolimus and a somatostatin analogue after disease progression. Local control was achieved, and the patient's general condition has been maintained despite slow progression of liver metastases. This case suggests that primary tumor resection may be a useful treatment option in selected patients with metastatic atypical pulmonary carcinoid.
