Urachal Adenocarcinoma: A Rare Primary Cancer Managed With FOLFOX Chemotherapy

Urachal adenocarcinoma (UA) represents a rare subset of bladder tumors involving a urachal remnant. Incidental gross hematuria is often the only presenting symptom, with patients often presenting late in their course, thereby imparting an overall poor prognosis. Although there are prior case reports, there is little literature reported and no standardized treatment guidelines. We report a case of a middle-aged male who presented with incidental gross hematuria after a fall. Workup indicated the presence of a calcified bladder dome mass and pathology reported a primary urachal adenocarcinoma with pelvic nodal involvement. Patient underwent surgical resection and subsequent adjuvant, systemic chemotherapy regimen with leucovorin, fluorouracil, and oxaliplatin (FOLFOX). We hope to bring greater awareness to this rare cause of bladder malignancy.
