Oral leiomyoma

A case report on a rare lesion in oral cavity

Abstract

Introduction: Leiomyoma, a benign tumour of smooth muscles, often affects uterine
myometrium, GIT, skin and lower extremities of women of middle age group. Its
occurrence in oral cavity is quite rare with reported incidence of 0.065%. It is contemplated
that in oral cavity leiomyoma arise from smooth muscle wall of blood vessels chiefly
affecting lips, tongue, palate, buccal mucosa, and rarely gingiva and mandible. Clinically
the disease exhibits as a slow growing asymptomatic mass, occasionally associated with
pain. Histopathological study is mandatory to help determine the diagnosis due to deceptive
clinical appearance. Surgical excision is widely accepted as the best treatment modality
with rare recurrence. Objective: The rationale of this case report is to help improve
our understanding of this rare disease (oral leiomyoma) and to report its occurrence
in the literature. Case Report: We report a rare case of a 25 years old female patient
presenting with the chief complaint of a slow growing mass since 6 months, diagnosed
as leiomyoma after clinical and histopathological examination. Conclusion: Leiomyoma
is a benign tumour of smooth muscles with rare presentation in the oral cavity with good
prognosis. Due to deceptive clinical and histopathological characteristics it is important to
meticulously evaluate clinically and histopathologically to arrive at conclusive diagnosis.
