Abstract
Two cases of small cell tumor of the uterine cervix are reported in which electron microscopic studies indicated that the tumor cells were of neural crest origin. Both tumors behaved aggressively, and metastatic involvement of pancreas was demonstrated in one patient, while the second patient developed liver metastasis. The need to distinguish these neoplasms from squamous cell carcinoma of the cervix is stressed. The tumors are compared with small cell neuroepithelial neoplasms previously reported as adult neuroblastomas. Cancer 43:1138–1145, 1979.
