[Small cell carcinoma of urinary bladder. A case report].

Abstract

A 57-year-old male patient was admitted because of a severe lumbar pain and gross hematuria. The rectal examination revealed a fist-sized soft tissue mass in the small pelvic space. A huge non-papillary tumor, which occupied the intravesical space, was found on cystoscopic examination. CEA IAP, TPA, CA19-9 and NSE were abnormally elevated in the serum. The pelvic CT scan shown an enormous polypoid tumor arising from the anterior vesical wall, while no abnormal lesion was found in the head, neck, chest and abdominal CT scans. The bone scintigraphy revealed multiple abnormal accumulations. The transurethral biopsy of the tumor was carried out. The pathological examination revealed homogeneous and small tumor cells arranged in sheet and solid patterns, which were positive for the anti-NSE stain and anti-NF stain, but negative for Grimelius stain. The final diagnosis was small cell undifferentiated carcinoma of the urinary bladder. The patient died of cancer five months after diagnosis.
