A rare case of oral leiomyoma mimicking a peripheral giant cell granuloma

Leiomyoma is a benign tumor of the smooth muscle, Occurance in the oral cavity is consider rare probably because of the paucity of the smooth muscle, with frequencies varying between 0.016% and 0.065% that occurs most frequently in the uterine myometrium, gastrointestinal tract and skin. The highest incidence occurs between the age group of 40 to 50 years. Very few cases have been reported in children. The most common intraoral sites are lip, palate, and tongue. Most of the lesions are asymptomatic, although occasionally tumors can be painful. The size may be 1 to 2 cm in diameter. Usually tumors are pedunculated, mimicking like various soft tissue tumors of the oral cavity and lead to a diagnostic dilemma to the clinician. The diagnosis is mainly confirmed by histological studies and special stains that confirm the smooth muscle origin. The surgical excision is the best line of treatment and recurrence is very rare.
