A case of primary carcinoma of the fossa navicularis of the male urethra is discussed. The lesion presented as an ulcerative process that circumferentially involved the external urinary meatus in a sixty-three-year-old man. Initially, the lesion was confused with a superficial carcinoma of the penis, since results of urethroscopic examination were normal. Following midshaft penectomy, despite normal gross appearance of the distal urethra, histologic examination indicated poorly differentiated epidermoid carcinoma along the mucosa of the distal urethra up to the line of surgical resection. Subsequent total penectomy showed only a small area of residual tumor at the line of previous resection. Lymphadenectomy was not performed. The patient remains alive without evidence of residual disease five years later.
本文讨论了一例男性尿道舟状窝原发性癌的病例。该病变表现为溃疡性病变，累及一名63岁男性的尿道外口周围。最初，由于尿道镜检查结果正常，该病变被误诊为阴茎浅表癌。阴茎中段切除术后，尽管远端尿道外观正常，但组织学检查显示远端尿道黏膜直至手术切除线处存在低分化表皮样癌。随后的全阴茎切除术显示，在先前切除线处仅残留一小片肿瘤。未进行淋巴结清扫术。五年后，患者仍然存活，无残留疾病迹象。
