軟口蓋から舌, 顎下部に及ぶ先天性奇形腫の1例 A case of an intraoral congenital teratoma involving the soft palate, tongue, and submandibular tissue
A teratoma involving the soft palate, tongue, and submandibular tissue in a female neonate is reported. Maternal polyhydramnios suggesting fetal anomalies was diagnosed at the 32nd week of pregnancy, and delivery was accomplished by cesarean section at the 37th week. Since the newborn had a severe respiratory disorder due to an intraoral tumor, immediate intratracheal intubation and resuscitation were done. The intraoral multilocular tumor arose from the soft palate and extended to the tongue, oral floor, and submandibular region. The intraoral tumor was partially enucleated at birth, and the rest was completely enucleated by an intraoral and extraoral approach under general anesthesia after 4 months.<BR>Histologically, the tumor was diagnosed as a mature teratoma. This case shows the importance of the prenatal diagnosis of fetal anomalies.
