Odontogenic tumors are derived from epithelial, ectomesenchymal and/or mesenchymal elements that are or have been a part of the tooth-forming apparatus. Of all the odontogenic tumors, calcifying epithelial odontogenic tumor accounts for 1% of the cases. Approximately 200 cases have been reported to date. There is no sex predilection, with a 2:1 predilection for the mandible, mostly in the premolar/molar region. It is often locally invasive. Most often, it is associated with an impacted tooth, is asymptomatic and requires biopsy for diagnosis. Presented here is a rare case of an intraosseous calcifying epithelial odontogenic tumor surrounding a supernumerary tooth. Furthermore, the occurrence of this tumor in the anterior maxilla (an uncommon site) in a pediatric patient makes it rarer. Although the present case was asymptomatic, root resorption and displacement of adjacent teeth necessitated its surgical removal. The lesion was surgically enucleated and histopathological examination confirmed calcifying epithelial odontogenic tumor, showing abundant calcifications in the form of Liesegang rings.
牙源性肿瘤起源于上皮、牙源性间充质和/或间充质成分,这些成分是或曾经是牙齿形成器官的一部分。在所有牙源性肿瘤中,钙化上皮性牙源性肿瘤占病例的1%。迄今为止,大约已报道200例。该肿瘤无性别倾向,下颌骨与上颌骨的发病比例约为2:1,多发生于前磨牙/磨牙区。它常具有局部侵袭性。多数情况下,它与阻生牙有关,无症状,需要活检来诊断。本文报告1例罕见的围绕多生牙的骨内钙化上皮性牙源性肿瘤。此外,该肿瘤发生于儿童患者的上颌前部(一个不常见的部位),使其更为罕见。尽管本例无症状,但相邻牙齿的牙根吸收和移位使其必须手术切除。病变经手术摘除,组织病理学检查确诊为钙化上皮性牙源性肿瘤,可见呈莱氏环形式的大量钙化。
