Peripheral ameloblastoma (PA) is a rare benign peripheral odontogenic tumor arising in the gingiva and in the overlying mucosa of tooth-bearing areas of the jaws. Recent data suggestthat the recurrence rate is directly related to inadequate surgical excision. This case of a 71-year-old man reports a poorly delineated mass effecting the gum of the left mandibular canine-premolars area histologically corresponded to PA. In complement to clinical visual examination of such a poorly delineated, non-exophytic and non-dyschromic inflammatory lesion, medical infrared thermography (MIT) - a non-invasive, non-ionizing and real-time imaging technique - was used to optimize the soft tissue margins, and a marginal bone resection was performed. MIT has also been found to be a useful tool in monitoring the absence of diseased tissue crossing the excisional margins at the end of the operation to minimize the risk of recurrence. After two years of follow-up, no local recurrence was found.
外周型造釉细胞瘤（PA）是一种罕见的良性颌骨外周牙源性肿瘤，发生于牙龈和牙齿覆盖区域的黏膜。最近的数据表明，复发率与手术切除不充分直接相关。本例为一名 71 岁男性，其左侧下颌尖牙-前磨牙区牙龈出现边界不清的肿块，组织学上符合 PA。为了更好地界定边界，除了对这种边界不清、非外生性和非色素性炎症性病变进行临床肉眼检查外，还使用医学红外热成像（MIT）——一种非侵入性、非电离和实时成像技术——对软组织边缘进行优化，并进行了边缘骨切除。研究还发现，MIT 是一种有用的工具，可用于监测手术结束时病变组织是否越过切除边缘，以最大限度地降低复发风险。经过两年的随访，未发现局部复发。
