[A local gingival swelling which was based on a peripheral giant cell lesion].

A 29-year-old woman consulted her dentist about a localgingival swelling which bled during tooth-brushing and had been present for 1 year. In the differential diagnosis, epulis gravidarum, a peripheral giant cell lesion, and peripheral ossifying granuloma were considered. After surgical removal, histopathological examination revealed a peripheral giant cell lesion. The presence of a peripheral giant cell lesion requires thorough excochleation of the underlying bone. If the bone is cleaned thoroughly, recurrence is rare.
