We report the case of a 77-year-old man who presented with a polypoid tumor in the distal urethra. It was excised, and a histological diagnosis of malignant melanoma was made. The patient had no history of previous cutaneous biopsies or suspicious pigmented lesions; therefore, the melanoma was considered to be primary in the urethra. The patient declined therapy and died 28 months later with local tumor progression. The autopsy revealed a widespread metastatic disease. The male urethra is rarely the primary site of a malignant melanoma. This event has so far been described in about 45 patients. The case is discussed in view of the pertinent literature.
我们报告了一例77岁男性患者，其远端尿道出现息肉样肿瘤。肿瘤被切除，组织学诊断为恶性黑色素瘤。该患者既往无皮肤活检或可疑色素沉着病变史；因此，黑色素瘤被认为是原发性尿道肿瘤。患者拒绝治疗，28个月后因局部肿瘤进展死亡。尸检显示有广泛的转移性疾病。男性尿道很少是恶性黑色素瘤的原发部位。迄今为止，约45例患者有此类病例报道。结合相关文献对该病例进行了讨论。
