[A case of benign pulmonary metastasis from ovarian immature teratoma].
A thirty one-year-old female underwent resection for pulmonary metastatic tumor from immature ovarian teratoma (G-II). Resected specimens from the lung revealed no malignant findings in the cystic teratoma (G-0). We speculated this finding might be due to retroconversion of ovarian immature teratoma. Retroconversion of ovarian immature teratoma is rarely reported and no report was found which dealt with pulmonary metastatic lesion histologically.
