A male presenting with a primary mucinous bladder carcinoma: a case report.

BACKGROUND

The primary mucinous adenocarcinoma of the bladder is an extremely rare urologic entity, which is found in less than 2% of all urinary bladder tumours and is often presented as metastatic.

CASE PRESENTATION

A 69-year old male patient was diagnosed with a primary mucinous adenocarcinoma of the bladder after undergoing a transurethral resection of a bladder tumour and complete examination of the entire gastrointestinal tract to rule out other primary cites. Immunohistochemistry confirmed the nature of the tumour. The patient underwent a radical cystoprostatectomy with en block bilateral pelvic lymphadenectomy and urinary diversion with a Bricker ileostomy.

CONCLUSION

The primary adenocarcinoma creates a diagnostic dilemma, since it cannot be easily differentiated by the adenocarcinoma that originates from the colon and the prostate. We advocate the radical surgical management, after exclusion of any primary malignant sites related to the gastrointestinal tract. The immunohistochemistry has a leading role, assisting with the differential diagnosis.
