Primary malignant melanoma of the trachea is extremely rare. We report here the first case of primary tracheal malignant melanoma in the asymptomatic stage. Incidentally, this 73-year-old man was found to have a flat tumor at the upper trachea on chest computed tomography scans. The tumor was surgically resected with end-to-end anastomosis and was diagnosed to be primary malignant melanoma of the trachea. Four months after the surgical resection, cervical lymph node metastasis was found. Despite the resection of metastatic lymph nodes and six courses of chemotherapy, he died of cachexia approximately two years after the discovery of the tracheal tumor.
气管原发性恶性黑色素瘤极为罕见。我们在此报告首例处于无症状阶段的原发性气管恶性黑色素瘤病例。偶然间，在胸部计算机断层扫描中发现这位73岁男性的气管上段有一个扁平肿瘤。该肿瘤通过端端吻合术进行了手术切除，被诊断为气管原发性恶性黑色素瘤。手术切除四个月后，发现有颈部淋巴结转移。尽管切除了转移淋巴结并进行了六个疗程的化疗，但在发现气管肿瘤约两年后，他死于恶病质。
