title: A ureteral small cell carcinoma mixed with malignant mesodermal and ectodermal elements: a clinicopathological, morphological and immunohistochemical study.
abstract: A 60-year-old male with a small cell carcinoma of the right lower ureter is presented. The tumor mainly comprised a small cell carcinoma but also included a full variety of histological types such as transitional cell carcinoma, squamous cell carcinoma, adenocarcinoma, leiomyosarcoma and chondrosarcoma. Immunohistochemical staining was positive for neuron specific enolase and cluster 1 small cell lung cancer antigen/N-CAM in the small cell carcinoma and S-100 in the chondrosarcoma component. The patient underwent a right nephroureterectomy, and received prophylactic radiation of the pelvic and para-aortic lymph node regions and cisplatin and etoposide combination chemotherapy. Eight months after the chemotherapy, a transitional cell carcinoma was found in the bladder neck, and a cystectomy with urethrectomy performed. To our knowledge, this is the second report of a small cell carcinoma originating from the ureter.
