Repeated observations have been made of certain differences in the frequency and microscopic structure of neoplasms of the ovary.* The purpose of this report is to analyze the pathologic data from 331 patients who had 336 ovarian tumors. The discrepancy is due to the fact that five patients had two histologically distinct synchronous tumors.

MATERIAL, METHODS, AND CLASSIFICATIONS  The material was selected from a total of 478 cases of ovarian neoplasms surgically treated at the Los Angeles County Hospital from Jan. 1, 1944, to Dec. 31, 1953. This study includes only histologically verified cases for which complete clinical records were available. A complete analysis of the clinical data from this study will be included in another paper. No attempt is made to give a historical review of ovarian tumors, review their histogenesis or discuss the embryogenesis of the ovary. Approximately 142 cases were excluded because of lack of microscopic sections,
