Peripheral or extraosseous odontogenic tumors are rare oral soft tissue enlargements which demonstrate the same histologic features of their intraosseous counterparts but emerge in gingiva and mucosa. In this paper we report a case of peripheral odontoma in a 12-years-old female patient presented asymptomatic swelling in the palatal site. After the clinical and radiographic examination, excisional biopsy was applied to the lesion located entirely in the soft tissue of maxillary incisors. Histopathologically presence of tooth-like structures containing dentin with regular canals and partly enamel matrix were observed. Our aim is to present the extremely rare case of peripheral odontoma and to review the literature for demonstrating the frequency and clinicopathologic features of this entity.
外周或骨外牙源性肿瘤是罕见的口腔软组织增大，其表现出与骨内肿瘤相同的组织学特征，但出现在牙龈和黏膜中。本文报告了一例 12 岁女性患者的外周牙瘤病例，该患者无症状性腭部肿胀。经过临床和影像学检查，对位于上颌切牙完全位于软组织内的病变进行了切除活检。组织病理学观察到存在牙齿样结构，包含有规则管腔的牙本质和部分釉基质。我们的目的是报告外周牙瘤这一极其罕见的病例，并通过文献复习来阐述该实体的发病率和临床病理特征。
