Malignant melanoma comprises 1%-3% of all malignant tumors of the gastrointestinal tract. The small bowel melanoma is an extremely rare malignancy. Very few cases have been reported in the literature. The small intestine is mostly affected by the metastatic tumors of the primary lesions especially cutaneous. This malignancy is diagnosed at the late stages as the patient remains asymptomatic. In this report we present a case of malignant melanoma arising from the small bowel in a 58-year-old male. There was no primary lesion in the eye, skin, anus, rectum or elsewhere in the body. The patient was treated with surgery. Afterward the patient presented to the emergency room with respiratory distress for which he was on ventilator support, sadly the patient died after 10 days. Malignant melanoma is an aggressive tumor and does not respond well to chemotherapy or radiotherapy.
恶性黑色素瘤占胃肠道所有恶性肿瘤的1% - 3%。小肠黑色素瘤是一种极其罕见的恶性肿瘤。文献中报道的病例极少。小肠主要受原发性病变尤其是皮肤转移性肿瘤的影响。这种恶性肿瘤在晚期才被诊断出来，因为患者一直没有症状。在本报告中，我们呈现了一例58岁男性小肠恶性黑色素瘤病例。眼部、皮肤、肛门、直肠或身体其他部位均未发现原发性病变。该患者接受了手术治疗。之后，患者因呼吸窘迫被送往急诊室，接受了呼吸机支持治疗，遗憾的是，患者在10天后死亡。恶性黑色素瘤是一种侵袭性肿瘤，对化疗或放疗反应不佳。
