Primary urachal carcinomas are very rare urological malignancies. In the present article we report an unusual case of a small cell carcinoma with neurendocrine features and adenocarcinoma arising in the urachus, and review the literature. The results of the immunohistochemical studies are presented.

D014497	Urachus	An embryonic structure originating from the ALLANTOIS. It is a canal connecting the fetal URINARY BLADDER and the UMBILICUS. It is normally converted into a fibrous cord postnatally. When the canal fails to be filled and remains open (patent urachus), urine leaks through the umbilicus.

D018278	Carcinoma, Neuroendocrine	A group of carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue cells", granular chromatin, and an attenuated rim of poorly demarcated cytoplasm. Neuroendocrine tumors include carcinoids, small ("oat") cell carcinomas, medullary carcinoma of the thyroid, Merkel cell tumor, cutaneous neuroendocrine carcinoma, pancreatic islet cell tumors, and pheochromocytoma. Neurosecretory granules are found within the tumor cells. (Segen, Dictionary of Modern Medicine, 1992)	Carcinomas, Neuroendocrine,Neuroendocrine Carcinoma,Neuroendocrine Carcinomas
