Ovarian extraembryonal teratoma. II. Endodermal sinus tumor mixed with other germ cell tumors.
From the files of the Emil Novak Ovarian Tumor Registry, 18 cases of mixed ovarian germ-cell neoplasms containing endodermal sinus tumor as one element have been reviewed. The data regarding the patient age, presenting symptoms, gross appearance of the tumors, and response to therapy are similar to those reported in a previous series of pure endodermal sinus tumors. Response to all modes of therapy is disappointing but there is growing evidence that combination chemotherapy should be added to surgical excision as a routine part of therapy in such patients. The rarity of this lesion is such that meaningful data are likely to be available only if individual and institutional experiences are combined in central tumor registries.
