Background: Sarcomatoid carcinoma is an uncommon malignancy, represents only 0.1% to 0.3% of carcinomas.
Methods: The medical records of all the patients who underwent consecutive cystectomy and the TURBT specimen sent to pathology department of Sardar Patel Medical College, Bikaner, were retrospectively analysed. Detailed medical history was noted age, gender, indication for surgery, surgical procedure, tumour localization in the urinary bladder, diameter of the lesion after fixation with 10% formalin, and overall incidence of tumour reviewed in detail.
Results: Out of the total 541 patients, 41 were found to have histological evidence of benign lesions of the urinary bladder, hence not included in the study. Out of 500 patients of urinary carcinoma 1 patient was found to have histological evidence of sarcomatoid carcinoma which was further confirmed by immunohistochemistry. The patient was 29 years old male. Gross haematuria was the clinical presentation. Radical cystectomy was performed. The tumour was polypoid, located on left posterolateral wall of the bladder with dimension of 10X7X6 cm.
Conclusion: Sarcomatoid carcinoma is a rare variant with different therapeutic and diagnostic implications, presenting with gross haematuria. Sarcomatoid carcinoma was diagnosed on histological and immonohistological staining.
