Primary non-bilharzial Squamous Cell Carcinoma of Urinary Bladder: An interesting report of two cases

Bladder cancer is the most common malignancy of urinary tract. Urothelial carcinoma accounts for 90-95% of bladder cancers and rest 5-10% includes other epithelial and mesenchymal tumors. Squamous cell carcinoma is a very uncommon malignancy of urinary bladder and accounts for only 1-3% of all bladder cancers. Squamous cell carcinoma can be classified as bilharzial and non bilharzial associated depending on epidemiology, pathogenesis, and clinicopathological characteristics. Here we present two cases of non bilharzial Squamous cell carcinoma in 73 years and 85 years old male patients who presented with decreased frequency and pain during micturition and painless Hematuria respectively. On computed tomography bladder wall thickening was reported in both the cases. Transurethral resection of bladder tumour was done and histopathological evaluation confirms the diagnosis of well differentiated Squamous cell carcinoma in both the cases with muscle invasion in the second case. Both the patients are on regular follow up and doing fine for last six months and four months respectively.
