Background
The peripheral giant cell granuloma has an unknown etiology, with some dispute as to whether this lesion represents a reactive or neoplastic process. However, most authorities believe peripheral giant cell granuloma is a reactive lesion. See image below.
This peripheral giant cell granuloma involved the maxillary gingiva associated with an erupting central incisor of a 6-year-old girl. The referring doctor had suggested a diagnosis of eruption cyst; however, an eruption cyst would immediately collapse once the tooth had disrupted its roof. Epidemiology
Frequency
United States
Peripheral giant cell granuloma is uncommon but not rare. Precise estimates of its incidence and prevalence in the general population have not been definitively determined.
Mortality/Morbidity
No mortality is associated with peripheral giant cell granuloma, and the lesion has minimal morbidity. Malignant transformation has never been reported.
Race
No known racial predilection is associated with peripheral giant cell granuloma.
Sex
Most reports describe a slight female predilection.
Age
A wide age range of patients can be affected, although most patients are in the fourth to sixth decades of life at the time of diagnosis of this lesion. The mean age of patients at the time of diagnosis is typically 38-42 years.
