Urachal Adenocarcinoma: a Case Report and Review of the Literature.

Urachal adenocarcinoma is one of the rare and aggressive neoplasms that often presents at an advanced stage and has a poor prognosis. Urachal adenocarcinoma makes up 0.17 to 0.34% of all bladder carcinomas. Patients commonly present with hematuria. Wide local excision of urachal mass with umbilicus and surrounding soft tissue en bloc combined with partial or radical cystectomy and bilateral pelvic lymphadenectomy is considered to be the primary surgical management. However, many publications in literature report that en bloc removal of tumor with umbilicus, entire urachal ligament, and bladder dome alone has long-term survival and disease-free period. Here, we present a case of a 50-year-old post-menopausal female patient with a fungating mass in the umbilical region of size approximately 10 cm in maximum diameter with mucopurulent discharge from the mass. The patient had no history of any hematuria, mucinuria, burning micturition, or any particles in urine. A laparotomy was performed, and tumor mass along with the cuff of the bladder dome was removed as en bloc along with umbilectomy. This case report highlights a rare case of urachal adenocarcinoma with a fungating mass of large size in a female patient which is otherwise more commonly seen in males. A review of published literature is also presented.
