Primary urachal adenocarcinoma: a rare case report

Abstract

Primary urachal carcinoma is a very rare cancer with a poor prognosis. It generally presents as a high-grade, high-stage tumor, and in most cases the patient has developed regional or distant metastasis at the time of presentation. Here, we report a very interesting case of primary urachal adenocarcinoma with signet ring cell carcinoma in a 58-year-old male who presented with a lower abdominal mass and discomfort. In this case, urachal carcinoma was successfully treated with surgery using an extended partial bladder cystectomy approach with excision of the urachal mass and umbilicus. The patient also underwent systematic chemotherapy with 5-fluorourical and cisplatin. During the 12-month follow-up period, the patient did not experience recurrence or metastasis. Overall, we found that an organ preserving extended partial cystectomy along with chemotherapy was an optimal treatment method that helped improve the patient's quality of the life with no recurrence of cancer so far.
