Congenital epulis is a rare benign localized mass in newborns’ gingiva, many of which are solitary. We experienced an extremely rare case of a girl with congenital epulis lesions in both the maxillary and mandibular gingiva.
The maxillary mass was located in a socket of the anterior region, pedunculated and with a maximum diameter of 25 mm. This mass was the cause of a suckling disorder and there was also the concern of choking if it was shed. Therefore, it was resected under local anesthesia on the day of birth. The mandibular mass shrank and disappeared spontaneously during 10 months of follow-up.
The resected maxillary lesion showed solid growth of cells with low N/C ratio and abundant PAS-positive cytoplasmic granules in the mucosal epithelium, accompanied by background vascular growth. Immunologically, the lesion was positive for vimentin and negative for S-100 protein, CD68, and CD163. Based on these findings, congenital granular cell tumor was diagnosed.
There have been no reports of recurrence of congenital epulis following excision, and there have been cases of spontaneous disappearance. Thus, taking into account invasiveness to the body of the newborn baby, it was considered best to examine the response to each mass separately in accordance with its size, shape, location, and growth tendency.
