We present an autopsy case of signet ring cell carcinoma of urinary bladder which underwent widespread metastsis through nearly entire organ. The patient, 45-year old male, suffered from hematuria, dysuria and flank pain for 6 months. Under the diagnosis of the signet ring cell carcinoma by the cystoscopic biopsy, radical cystectomy and ileocutaneous ureteral division were performed. But he died after 11-months after the diagnosis. The autopsy confirmed the widespread metastasis at the lung, kidney, adrenal gland, parathyroid gland, heart, stomach, ileum, spine, rib and meninges. The preveously resected urinary bladder discolosed the well defined fungating mass at the dome and anterio-lateral portion without apparent evidence of the remnant of the urachus. Histologically, the signet ring cells were predominent and focally mucinous pool floating the signet ring cells was noted. We could find several foci of the well differentiated adenocarcinoma and poorly differentiated adenocarcinomas. The above findings may reflect that the origin of carcinoma may be from the multipotential transitional cell epithelium.
