Abstract
Malignant transformation of urachal adenoma is exceedingly rare, with intestinal metaplasia as the most common contributing mechanism. It is recommended that a urachal adenoma be regarded as a pre-malignant condition and be subject to endoscopic surveillance. A local en block excision of the tumor mass with urachalectomy and umbilectomy results in possible long-term survival. The median survival after platinum-based chemotherapy is limited for patients with extravesical disease. Here we report a case of synchronous urothelial carcinoma of the bladder and urachal adenoma that transformed into adenocarcinoma.
