Mandibular invasive odontogenic Fibromyxoma
Abstract
Odontogenic fibromyxoma is a rare benign lesion with an invasive character in its development. It is considered a variant of odontogenic myxoma, due to its controversial mesenchymal origin, more frequent in the female sex, between the second and third decades of life, associated to areas with adjacent dental structures and generally affecting the posterior mandibular region. The choice of treatment will be directly related to the size of the lesion, time of evolution, involvement of neighboring structures, among other elements to assess. We present the case of a female patient, 14 years old, referred to the maxillofacial surgery service of the hospital in Kitui, Kenya, for presenting an increase in volume in the right mandibular anterolateral region, approximately two years of evolution that caused her difficulty chewing and was associated with a little pain. The intraoral examination revealed that the increased volume occupied the right vestibular and lingual region, absence of vestibular groove background, bulging of the cortical, dental mobility of the teeth involved and integrity of the oral mucosa. Laboratory studies were within normal limits and the radiographic study showed a large bone destruction associated with injury. The primary histological result showed the diagnosis of odontogenic fibromyxoma, corroborated in the postoperative result. The lesion was resected en bloc and a titanium mandibular plate was placed to continue postoperative follow-up.
