Peripheral Ameloblastoma (PA) is a benign odontogenic tumor, arising from the cell rest of Serres, reduced enamel epithelium and basal cells of the surface epithelium. Peripheral ameloblastoma is a rare odontogenic neoplasm occurring commonly in the mandibular gingiva. PA clinically resembles other peripherally occurring lesions like pyogenic granuloma, peripheral ossifying fibroma, peripheral giant cell granuloma, and squamous papilloma. The recurrence rate of PA is 16-19% which demands a straight follow up. We report a case of recurrent peripheral ameloblastoma occurring in a 72-year old male located in the mandibular lingual gingiva in relation to the 44, 45 element's regions. The patient had a primary lesion excised from the same site 6 years before which was diagnosed as ameloblastoma.
外周型成釉细胞瘤（PA）是一种良性牙源性肿瘤，起源于Serres细胞残余、釉质发育不全上皮及表面上皮的基底细胞。外周型成釉细胞瘤是一种罕见的牙源性肿瘤，常见于下颌牙龈。PA在临床上类似于其他外周性病变，如化脓性肉芽肿、外周骨化性纤维瘤、外周巨细胞肉芽肿和鳞状乳头瘤。PA的复发率为16%-19%，这需要进行直接随访。我们报告一例复发性外周型成釉细胞瘤，发生于一名72岁男性下颌舌侧牙龈，与44、45牙位区域相关。该患者6年前曾在同一部位切除过原发性病变，当时诊断为成釉细胞瘤。
