Peripheral ossifying fibroma on the mandible: report of atypical presentation case

ABSTRACT Peripheral ossifying fibroma (POF) is a benign lesion, nodular, firm on palpation; the base is sessile or pedunculated; similar in color to the mucosa and epithelium; it may be preserved or ulcerated. It is prevalent in female and exclusively affects the gingiva. It is usually associated with irritating factors such as caries, dental plaque, among others. The objective of the present study is to report the case of a 27-years-old female patient, presenting a lesion in the mandible, complaining of an increased volume. Surgical excision was the treatment of choice. The patient is 24 months postoperatively with no signs of relapse.

摘要：外周性骨化性纤维瘤（Peripheral ossifying fibroma, POF）是一种良性病变，表现为结节状病灶，触诊质地坚硬；基底呈广基或带蒂；色泽与黏膜及上皮组织相近；病灶可保持完整或发生溃疡。该疾病好发于女性，且仅累及牙龈组织，通常与龋病、牙菌斑等刺激因素相关。本研究旨在报告1例27岁女性患者的病例：该患者下颌出现病灶，主诉为肿物体积增大。手术切除为首选治疗方案，术后随访24个月，患者未见复发征象。
