Lingual mandibular salivary gland inclusion (Stafne defect) is a developmental anomaly represented by a bone concavity usually containing submandibular gland tissue. The posterior mandible region, particularly at the angle and below the mandibular canal, is the common location, and the anterior mandibular variants occur rather seldom. The latter is usually observed in the premolar and cuspid region, or more rarely in the symphysis, as a round or ovoid radiolucency sometimes appearing superimposed over the teeth's apices, resembling a true cystic lesion or an odontogenic tumor. We report an additional case of anterior lingual mandibular salivary gland defect occurring in a 42-year-old white man. It presented as an asymptomatic radiolucency located on the left side of the mandible, in the region of an absent second premolar and first molar, above the alveolar canal, mimicking a residual cyst. Histopathologic examination of the "cyst" content revealed the absence of a cyst lining and the presence of normal sublingual gland tissue.
舌下颌涎腺包涵体（斯塔夫内缺损）是一种发育异常，表现为通常包含下颌下腺组织的骨凹陷。下颌骨后部区域，特别是在下颌角和下颌管下方，是常见部位，而下颌前部的变异情况很少见。后者通常见于前磨牙和尖牙区，或更罕见于下颌联合处，表现为圆形或椭圆形的透射区，有时出现在牙齿根尖上方，类似真正的囊性病变或牙源性肿瘤。我们报告了一例发生在一名42岁白人男性的额外的前舌下颌涎腺缺损病例。它表现为位于下颌骨左侧、缺失的第二前磨牙和第一磨牙区域、牙槽管上方的无症状透射区，类似残余囊肿。对“囊肿”内容物的组织病理学检查显示无囊肿内衬，存在正常的舌下腺组织。
