臨床的に肺原発と考えられた悪性黒色腫の1手術例

A 78‐year‐old man who had an abnormal shadow on chest radiograph had detected by mass screening was admitted to our hospital. Chest CT scan revealed a pulmonary nodule in left S３, and transbronchial lung biopsy（TBLB）was performed. The pathological diagnosis was malignant melanoma. A histopathological examination of the biopsy specimen showed tumor cells which were positive for HMB-４５and S-１００. A systemic examination was done, but there were no lesions except for the lung. Therefore, we diagnosed this case as primary malignant melanoma of the lung, and left upper lobectomy was carried out. Although the patient underwent chemotherapy with DTIC after the operation, the patient died of disease２５months after the operation. Malignant melanoma of the lung is extremely rare only２１cases have been reported in japan.
