Small intestine melanomas are rare and the most of them are metastases from primary cutaneous neoplasms.
Below, we report two cases of small intestine metastatic melanoma with very different clinical presentation.
Still now, primary versus metastatic origin is often unclear. Small bowel melanoma is often asymptomatic. However, clinical picture can be various; it may occurs with non specific symptoms and signs of gastro-intetstinal involvement, like chronic abdominal pain, occult or gross bleeding and weight loss, or with an emergency picture due to intestinal intussusception, obstruction or, rarely, perforation.
Small bowel melanoma is rare and the diagnosis done late. Imaging techniques are recommended in order to obtain early diagnosis of gastrointestinal metastases.
小肠黑色素瘤很罕见，其中大多数是原发性皮肤肿瘤的转移瘤。
以下，我们报告两例小肠转移性黑色素瘤，其临床表现截然不同。
至今，原发性与转移性起源往往不明确。小肠黑色素瘤通常无症状。然而，临床表现可能多种多样；可能出现胃肠道受累的非特异性症状和体征，如慢性腹痛、隐匿性或显性出血及体重减轻，或因肠套叠、肠梗阻或很少见的穿孔而出现急症表现。
小肠黑色素瘤罕见且诊断较晚。建议采用影像学技术以便早期诊断胃肠道转移瘤。
