Abstract
A 50-year-old woman was admitted to our hospital for cough and dyspnea. Chest radiography and computed tomography showed a large mass opacity in the left lower lobe, stenosis of the left bronchus, mediastinal enlargement, and pleural effusion. Bronchoscopic examination showed a polypoid tumor in the left bronchus, and the pathological diagnosis of the biopsy specimen was malignant melanoma. Systemic staging studies revealed metastases of the parietal skin. We diagnosed this patient with primary malignant melanoma of the lung because the pulmonary lesion was large and solitary and no other primary organ was affected. We carried out a left lower lobectomy, chemotherapy, and radiation therapy, and this patient is still alive. Primary malignant melanoma of the lung is extremely rare, and so we report this case.
