Four Cases of Irritation Fibroma / 대한피부과학회지

ABSTRACT

Irritation(traumatic) fibroma is one of the most common soft-tissue lesions in the oral cavity and represents a reactive fibrous hyperplasia. It is usually found in adults, and sites of trauma such as the buccal and labial mucosa and tongue are commonly involved. The lesion usually present as smooth, dome-shaped or pedunculated nodules with pale pink color or color of surrounding mucosa. We report four cases of irritation fibroma. The patients were all women and in their teens, fifties, and sixties. The lesions were located in labial and buccal mucosa and tongue. Interestingly, we found HPV type 1a in one of them using polymerase chain reaction. The lesions were excised and there has been no recurrence. It is a less known disease among dermatologists despite its high prevalence. We think that this is the first report of irritation fibroma in Korean dermatologic literature.
