Pure primary small cell carcinoma of urinary bladder: A rare diagnostic entity
A 59-year-old male presented in the outpatient department of Urology, R G Kar Medical College and Hospital, Kolkata with the chief complaint of mild hematuria, particularly at the end of the micturition. Patient was a builder by profession and a chronic smoker. His past and family history was insignificant.\nThe patient's urine examination was positive for occult blood with microscopic presence of 3-6 RBC/hpf and negative growth on culture. Ultrasonograph of the urinay bladder revealed a large papillomatous mass measuring 5 × 4 cm arising from left superalateral wall of urinary bladder with no evidence of calculi. Contrast-enhanced computed tomography scan confirmed the anatomical location of the mass along with involvement of the adjacent musculature []. Patient underwent cystoscopy with biopsy of mass, which on histopathological examination was reported as poorly differentiated urothelial carcinoma.\nRadical cystoprostatectomy with pelvic lymphadenectomy along with Studer's neobladder reconstruction was done with ileal wall and the specimen was sent to the Department of Pathology for histopathological examination. Postoperative period was uneventful. Combined ascending and micturating cystourethrography done 4 weeks postsurgery, showed normal flow of contrast through penile urethra in ascending urethrogram along with normal outline of neobladder exhibiting feathery pattern of small intestine [].
