저자들은 24세 된 간질 임부의 신생아에서 발생한, Fetal Hydantoin 증후군의 한 소견으로 생각되는, 하치육 증식증 1례를 경험하였기에 문헌적 고찰과 함께 보고하는 바이다.

Fetal hydantoin syndrome is a birth defect and can be shown about 10% of the neonates who were exposed to diphenyl hydantoin during gestational period. This syndrome was discribed for the first time by Hanson in 1975, who reported craniofacial abnormalities, limb defects, and deficiencies in growth, developmental performance and intelligence as the most common findings. Recently we have experienced one case of gingival hyperplasia which was suggested of one of the typical findings of fetal hydantoin syndrome. We report a case of probable fetal hydantoin syndrom with the brief review of literatures.
