Metastasis of malignant melanoma to the bladder is rarely seen clinically with only 29 cases reported in English-language literature. However, autopsy series of melanoma patients have shown that metastasis to the bladder could be as high as 37%, implying that numerous cases remain undiagnosed. This report details a case of malignant melanoma metastasis to the bladder. Patient presented with severe anemia and history of gross hematuria. Computerized tomography (CT) revealed a 2.7 cm mass in the bladder. Cystoscopy confirmed presence of a mass. Patient underwent cystoscopy and transurethral resection of the tumor, revealed to be melanoma on pathology.
恶性黑色素瘤转移至膀胱在临床上很少见，英文文献中仅报道了29例。然而，黑色素瘤患者的尸检系列显示，膀胱转移率可能高达37%，这意味着许多病例仍未被诊断出来。本报告详细介绍了一例恶性黑色素瘤转移至膀胱的病例。患者表现为严重贫血和肉眼血尿病史。计算机断层扫描（CT）显示膀胱内有一个2.7厘米的肿块。膀胱镜检查证实有肿块存在。患者接受了膀胱镜检查和经尿道肿瘤切除术，病理检查显示为黑色素瘤。
