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.
一名31岁女性因未成熟卵巢畸胎瘤（G-II级）肺转移瘤接受了切除术。肺部切除标本显示囊性畸胎瘤（G-0级）无恶性表现。我们推测这一发现可能是由于卵巢未成熟畸胎瘤的逆转。卵巢未成熟畸胎瘤的逆转鲜有报道，且未发现有从组织学角度处理肺转移病灶的报告。
