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.
下颌颊侧分叶囊肿是一种罕见的炎症性牙源性囊肿。我们报告了两例以颌面部外软组织疼痛肿胀为主要表现的患者。口内检查发现下颌第一磨牙部分萌出。锥形束 CT 显示第一磨牙周围有界限清楚的囊性病变。组织病理学图像显示，囊肿壁被大量浆细胞、中性粒细胞和嗜酸性粒细胞浸润，内衬一层薄的非角化复层扁平鳞状上皮。最后，两名患者被诊断为下颌颊侧分叶囊肿，并采用囊肿摘除术和刮除术进行治疗。
