PRIMARY URINARY BLADDER SMALL CELL CARCINOMA MASQUERADING AS TRANSITIONAL CELL CARCINOMA: A DIAGNOSTIC AND THERAPEUTIC CHALLENGE
Dr. Sanjay Kumar, *Dr. Mansi Agarwal, Dr. Hemant Yadav and Dr. Rajeev Sen
Small cell carcinoma of the urinary bladder is an extremely rare tumor accounting for less than 1% of all cancers arising from the bladder. The tumor shares similar histological features with the small cell carcinoma originating at the other sites in body. However, its similar clinical features like the conventional transitional cell carcinoma of the bladder, tendency to present at a advanced stage and low immunoreactivity to the conventional neuroendocrine markers makes the early diagnosis challenging and simultaneously crucial for the patient’s survival.
Considering the very few number of case reports available in the literature and lack of the definitive data predicting the therapeutic response to various modalities, we, herein, describe a case of small cell carcinoma originating in the urinary bladder and diagnosed and treated in our institute.
