A case of signet ring cell adenocarcinoma of the bladder with spontaneous urinary extravasation.

Primary signet ring cell adenocarcinoma (PSRCC) of the bladder is a relatively rare variant of adenocarcinoma of the bladder with poor prognosis. Also PSRCC of the bladder presenting with spontaneous urinary extravasation is very rare. We present the case of a 48-year male who presented with spontaneous urinary extravasation and was diagnosed to have PSRCC of the urinary bladder on evaluation. He was treated with radical cystectomy and adjuvant chemotherapy. This report emphasizes the need to rule out other primary sites of adenocarcinoma in the body, which may metastasize to the urinary bladder.
