Extraosseous/peripheral Ameloblastoma (EPA) is a rare, benign odontogenic soft tissue tumour with the same histological characteristics as the more common intraosseous subtypes. The EPA appears in the soft tissue of the gingiva and the mucosa of the alveolar process often as unspecified painless swelling. The present case report describes an EPA in the aesthetic area of the left anterior maxilla. Based on the clinical finding the suspected diagnosis of a gingival cyst was made. Firstly, this case should highlight the importance of a proper histopathologic evaluation whenever a biopsy is performed. Furthermore, this report should illustrate a step-by-step procedure from the surgical re-excision of the EPA with a safetymargin to the healing phase to the aesthetic satisfying rehabilitation by using periodontal plastic surgery.
骨外/外周型成釉细胞瘤（EPA）是一种罕见的良性牙源性软组织肿瘤，具有与更常见的骨内型亚型相同的组织学特征。EPA常表现为牙龈软组织和牙槽突黏膜处未明确的无痛性肿胀。本病例报告描述了一例发生于左上颌前部美学区域的EPA。基于临床检查结果，初步诊断为牙龈囊肿。首先，该病例应强调活检时进行恰当组织病理学评估的重要性。此外，本报告应阐述从带安全切缘手术再次切除EPA到愈合阶段，再到通过牙周整形手术实现美学上令人满意的修复的一步步过程。
