A Case of Vesical Dome Transitional Cell Carcinoma Resembling Urachal Carcinoma / 대한비뇨기과학회지

ABSTRACT

Vesical dome tumors are classified, according to their origin, as either vesical or urachal. A case of vesical dome tumor was diagnosed as an urachal carcinoma preoperatively because CT scan and cystoscopic findings were suitable to the diagnostic criteria of urachal carcinoma, but the transurethral biopsy result was transitional cell carcinoma (TCC). The final histopathologic report after extended partial cystectomy revealed that the tumor was originated from vesical mucosa and an intact urachal remnant was found around the resected mass. In a tumor situated on the midline of bladder dome, a transurethral biopsy before curative operation is essential.
