The squamous odontogenic tumor (SOT) is a rare, benign, locally infiltrative neoplasm of the jaws that appears to originate from the rests of Malassez, gingival surface epithelium or from remnants of the dental lamina. SOT was first described by Pullon et al. (1975). Since then there has been paucity in the number of reported cases, especially in the Indian subcontinent. The tumor is often asymptomatic, although it can present with symptoms of pain and tooth mobility. The characteristic radiographic appearance is that of a triangular-shaped unilocular radiolucency associated with the roots of erupted, vital teeth and has a predilection for the anterior maxilla and the posterior mandible. Histologically, the tumor is characterized by the formation of variably sized nests and cords of uniform, benign-appearing, squamous epithelium with occasional vacuolization and keratinization. We report a case of SOT occurring in a 58-year-old male in the anterior mandible with unusual localization and appearance.
鳞状牙源性肿瘤（SOT）是一种罕见的、良性的、具有局部浸润性的颌骨肿瘤，似乎起源于马拉瑟上皮剩余、牙龈表面上皮或牙板残余。SOT最早由普伦等人（1975年）描述。从那时起，报告的病例数量很少，尤其是在印度次大陆。该肿瘤通常无症状，尽管也可能出现疼痛和牙齿松动的症状。其特征性的影像学表现是与萌出的活牙牙根相关的三角形单房性透射影，且好发于上颌前部和下颌后部。组织学上，该肿瘤的特征是形成大小不一的巢状和条索状结构，由形态一致、看似良性的鳞状上皮组成，偶尔有细胞空泡化和角化。我们报告一例发生在下颌前部的58岁男性的SOT病例，其具有不寻常的定位和表现。
