Carcinoma of urachus accompanied with calcification is rarely encountered. A 37-year-old man presented with the complaint of mucus discharge on voiding. A plain X-ray film of his abdomen showed the presence of calcification at the urinary bladder. A hemispheric tumor at the top of the urinary bladder was seen on cystoscopic examination. The results of urine cytology and cold-punch biopsy supported the diagnosis; carcinoma of urachus. En bloc segmental resection was performed. Histopathologically, the tumor was composed of moderately differentiated adenocarcinoma producing mucus. Now, he is alive and has no evidence of recurrence. This is the 9th report on carcinoma of urachus with calcification in the Japanese literature.
脐尿管癌伴钙化极为罕见。一名37岁男性因排尿时伴有黏液排出前来就诊。其腹部X线平片显示膀胱存在钙化。膀胱镜检查发现膀胱顶部有一个半球形肿瘤。尿液细胞学检查和冷切活检结果支持诊断：脐尿管癌。遂行整块节段性切除。组织病理学检查显示，肿瘤由产生黏液的中分化腺癌组成。目前，患者存活，无复发迹象。这是日本文献中关于脐尿管癌伴钙化的第9例报告。
