Primary malignant melanoma of the urethra is very rare. In the male, the distal urethra is the most common site. The histopathology does not usually differ from that of melanoma at other body sites. This report describes a case of urethral malignant melanoma which closely resembled urethral carcinoma. It showed both papillary and solid growth, and the diagnosis only became apparent from special stains. Pathologists should be aware of this rare occurrence.
原发性尿道恶性黑色素瘤非常罕见。在男性中，尿道远端是最常见的部位。其组织病理学通常与身体其他部位的黑色素瘤并无差异。本报告描述了一例酷似尿道癌的尿道恶性黑色素瘤病例。它表现出乳头样和实性生长，仅通过特殊染色才明确诊断。病理学家应知晓这种罕见情况。
