We report a mature solid teratoma of the fallopian tube in an elderly woman. This mass was noted on CT scan and considered metastatic in nature since following a bioptical diagnosis of endometrial adenocarcinoma. Hysterectomy and bilateral salpingectomy and ovariectomy were performed and a second minor mature solid teratoma was discovered inside the right ovary. Neoplasms of the fallopian tube are very uncommon and this is the first Italian case to be added to about other 60 of the literature. Moreover it joins minimum teratomatous diameter with maximum recorded age.
