摘要:

下颌颊分叉囊肿是一种罕见的炎症性牙源性囊肿。我们报告了2例因口外软组织肿痛而就诊的病例。口内检查可见部分萌出的下颌第一磨牙。锥束计算机断层扫描提示:此磨牙被囊性的透射影包绕。病理组织学检查显示:囊壁由一薄层非角化复层鳞状上皮覆盖,并有大量浆细胞、淋巴细胞、中性粒细胞浸润。结合以上临床资料,2例患者被诊断为下颌颊分叉囊肿。

关键词: 颊分叉囊肿, 牙源性囊肿, 第一恒磨牙

Abstract:

Mandibular buccal bifurcation cyst is a rare inflammatory odontogenic cyst. We reported two cases who complained of painful swelling of extraoral soft tissue. Intraoral examination revealed the partially erupted mandibular first molar. Cone beam computed tomography showed a well-defined cystic lesion surrounding the first molar. Histopathologic images showed the cyst wall was infiltrated by a large number of plasma cells, neutrophils and eosinophils, and lined with a thin layer of non-keratinized stratified squamous epithelium. Finally, the two patients were diagnosed as mandibular buccal bifurcation cyst and treated with cyst enucleation and curettage.

Key words: buccal bifurcation cyst, odontogenic cyst, permanent first molar
