Primary Squamous Cell Carcinoma of Urinary Bladder - A Rare Histological Variant.

Primary squamous cell carcinoma of urinary bladder is a rare histological variant of epithelial bladder tumours. Histopathological types are associated with significant disease outcome, so it is essential to find, on microscopy the exact type of urothelial carcinoma. Herewith, we present a 70-year-old male having 3 months history of difficulty in micturition, reduced frequency of urine and associated pain. On Contrast Enhanced CT scan abdomen pelvis, showed irregular large urinary bladder mass with hydroureter and hydronephrosis. Internal iliac group of lymphnodes was enlarged. On histopathology diagnosed as pure squamous cell carcinoma of urinary bladder grade II with muscle invasion. We are presenting this case for its clinical, radiological and histopathological findings.
