Oral Leiomyoma – A Rare Presentation in a Child

Abstract

Leiomyoma is a benign smooth muscle tumour most commonly found in the myometrium of the uterus GI tract skin and lower extremity of the body with abundant smooth muscle. These tumours have been reported to occur at any age and reported in literature as firm slow growing locally circumcised mass which may present as a submucosal nodule. The highest incidence occurs between the 4th to 5th decades of life. Occurrence is unusual and uncommon in paediatric and geriatric age groups. Its occurrence in oral cavity is a rare phenomenon due to the paucity of smooth muscle tissue in the oralperioral region. Most of the cases reported were in adults and very few cases were reported in children. Frequent intra-oral sites of occurrence include tongue lips palatal tissue buccal mucosa and retromolar trigone. The tumours are commonly asymptomatic although some tumours maybe symptomatic and painful. The diagnosis is confirmed by histological studies with the use of specific stains. Surgical excision of the lesion is reported to be the treatment of choice as recurrence is rare and patient responds well to the treatment. This report discusses about a case of rare occurrence of leiyomyoma in a 9-year-old girl who presented with a growth in the oral cavity on the right lower jaw extending to the retromolar region with associated difficulty in speech and chewing for past two months.
