颌骨的牙源性鳞状细胞瘤是很少见的肿瘤。1975年Pullon等首次对6例牙源性鳞状细胞瘤作了描述,以后又先后有过10例报告。由于病例太少,该肿瘤的生物学行为至今尚难确定。本文介绍两个病例,对其中一例作了电镜观察,同时对以前报道过的16例加上本文两例作一分析。病例1:59岁,男性。在作常规牙科X线检查中发现左侧下颌第一、第二双尖牙区有一1.0×1.5cm透光阴影,周界清楚。病人无症状,牙齿有活力。手术时发现肿瘤和第二双尖牙的近中面相粘连,颊舌侧骨皮质完整。肿瘤作保守性摘除。标本为1.5×1.2×0.5cm,质硬,切面灰白色,有轻度砂砾
Jaw odontogenic squamous cell tumor is a rare tumor. Pullon for the first time in 1975, such as 6 cases of odontogenic squamous cell carcinoma was described, and then there have been 10 cases have been reported. Due to the small number of cases, the biological behavior of the tumor has so far been difficult to determine. This article describes two cases, one of which was electron microscopy, at the same time on the previously reported 16 cases with the two cases for an analysis. Case 1:59 years old, male. For routine dental X-ray examination found in the left mandibular first, the second bicuspid area with a 1.0 × 1.5cm transparent shadow, the perimeter clear. Asymptomatic patients, dynamic teeth. The tumor was found to be adherent to the second median canine near the midpoint of the buccal and lingual cortical bone. Tumor for conservative removal. Specimens of 1.5 × 1.2 × 0.5cm, hard, white section, with mild gravel
