Recurrent Urachal Mucinous Adenocarcinoma Presenting as Bilateral Ovarian Tumors on Cesarean Delivery

Abstract

Secondary ovarian cancers, Krukenberg tumors, are a distinctive subset of metastatic tumors arising from the gastrointestinal tract (stomach, colon, and appendix), the biliary system, the breast, or other genital organs. These tumors account for 5% of all ovarian malignancies. Such metastases could mimic primary mucinous ovarian adenocarcinomas.1,2 Metastases from the urinary tract are uncommon.Primary adenocarcinoma of the bladder accounts for less than 1% of all bladder malignancies; one third of these tumors are urachal in origin.3 Urachal cancers are rare and tend to occur in older men (mean age, 50-60 years); however, it was described previously in a 15-year-old girl.4 Symptoms include hematuria, dysuria, frequency, urgency, and recurrent urinary tract infections.5 These tumors have a predilection to locally spread to the surrounding organs. Ovarian metastasis is a rare event and is infrequently reported in literature.
