Pyogenic granuloma arises from the connective tissue of the skin or mucous membranes. The oral mucosa is one of its most common sites.<BR>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.<BR>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.<BR>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.
