Fetiform teratoma (homunculus) is a term that has been given to a rare form of ovarian teratoma that resembles a malformed fetus. There are very few reported cases of this entity in the English language literature. In this report, we document a case of fetiform teratoma in a 23-year-old woman, gravida 0, who initially presented with a chief complaint of dyspareunia. The clinical and pathologic aspects of this rare entity are presented here, with a review of the English literature. Differentiating fetiform teratoma from the more highly developed fetus-in-fetu and ectopic pregnancy is also discussed.
胎儿样畸胎瘤（小人儿）是用于描述一种罕见的卵巢畸胎瘤的术语，其形似发育畸形的胎儿。英文文献中报道的该实体病例极少。在本报告中，我们记录了一例23岁、未孕女性的胎儿样畸胎瘤病例，该患者最初的主要诉求为性交困难。本文介绍了这一罕见实体的临床和病理特征，并对英文文献进行了综述。还讨论了胎儿样畸胎瘤与发育更成熟的胎中胎及异位妊娠的鉴别诊断。
