The chest computed tomography(CT)revealed a mass shadow of 60 mm in left lung. Bronchoscopic examination was done and it was diagnosed as non-small-cell lung cancer by cytology. The clinical stage was cT2bN1M0 and video-assistedthoracic surgery (VATS) left pneumonectomy with mediastinal lymph node dissection was performed. A lot of neoplastic cells which contained melanin in cytoplasm were recognized by pathology and the diagnosis of malignant melanoma was comfirmed. Lymph node metastasis were recognized in #10, #11, #12 and the pathological stage of a disease was pT2bN1M0, pStage IIB. Further examination to find another lesion after surgery was in vain suggesting primary site to be left lung. A adjuvant chemotherapy has not been done.
