Aggressive Myofibroma of Gingiva: A Case Report

Myofibroma is an uncommon spindle cell neoplasmof rare incidence in oral cavity. Typically, this lesion is seen in neonates and infants with few cases reported in adults. In the oral cavity, myofibroma occurs within the submucosal or intramuscular tissue and has a predilection for the tongue, buccal mucosa and lips. Microscopically, a typical biphasic pattern can be observed. Misdiagnosis includes benign and malignant spindle cell lesions of nerve tissue or smooth muscle origin, such as neurofibroma, leiomyoma and sarcomas. Thus, immunohistochemical staining is a useful tool to identify the nature of neoplastic cells and to reach an accurate diagnosis.Here is a case of this rare benign tumor of gingiva in a child of one and a half year of age.Surgical excision of the lesion was done under general anaesthesia. Histopathologic and immunohistochemical examination suggested the diagnosis of myofibroma.
