Abstract
A case of congenital epulis on the maxillary gingiva was found in a 2 year,3month-old Japanese female. Its histopathologic features corresponded to that of the so-called leiomyomatous hamartomas, which occur very rarely in the gingiva.
The findings were as follows:
Intraoral examination revealed a smooth, reddish gingiva-colored mass, attached to the palatal gingiva of the A⊥A region, measuring 8×5×4mm, with a pedicle.
Histopathologically, the lesion manifested the structure of the so-called leiomyomatous hamartoma, consisting of smooth muscle tissue, nerve fiber and muscular vessels. In addition, at the pedicle, there were myxomatous tissue and cartilage-like tissue.
No granular cells were detected.
The mass was excised with periosteal tissue under local anesthesia. The postoperative course was uneventful, and there was no evidence of recurrence after 9months of follow-up.
