Pyogenic granuloma arises from the connective tissue of the skin or mucous membranes. The oral mucosa is one of its most common sites.
We examined the clinical and pathological features of pyogenic granuloma of the oral cavity in 42 patients in our department during the past 20 years.
Clinically, the patients ranged in age from 1.5 to 87 years, and the pyogenic granuloma occurred in individuals of all ages. The lesion was slightly more prevalent in females (57.1%) than in males. The locations of the lesion were most frequent in gingiva (35.7%) and tongue (35.7%), and the remainder involved lip, buccal mucosa, palate. The duration of this lesion was from half month to five years.
Histopathologically, the lesion exhibitted granulomas associated with proliferation of dilated capillaries and infiltration of inflammatory cells. These histopathological findings of the lesion were nearly the same as those of capillary hemangioma.
