A Case Report of Primary Mucinous Adenocarcinoma of Urinary Bladder with Review of Literature

Abstract

The primary mucinous adenocarcinoma of the bladder is an extremely rare urologic entity, which is less than 2% of all urinary bladder tumours and often presents in advanced stage. A 68-year old gentleman was diagnosed with a primary mucinous adenocarcinoma of the bladder from biopsy of anterior abdominal wall ulcer. Immunohistochemistry was done to rule out metastasis from colon and prostate and it confirmed the nature of the tumour. As the patient presented in advanced (stage IV), palliative intent chemotherapy with gemcitabine and cisplatin was administered, however he succumbed to the illness after one cycle of chemotherapy. The primary adenocarcinoma of urinary bladder creates a diagnostic dilemma, as it is difficult to differentiate metastatic adenocarcinoma of the colon and prostate. The immunohistochemistry has a leading role, aiding in diagnosis.
