Odontogenic keratocyst (OKC) is a developmental, noninflammatory chronic cyst that may be unilocular or multilocular. Histologic features of OKC are pathognomonic. A 41-year-old male patient presented for emergency evaluation of a buccal gingival swelling in the area of teeth 34 and 35. Incision and drainage were followed 3 weeks later by surgical curettage and guided tissue regeneration using Puros allograft and resorbable membrane. Biopsy of the excised tissue revealed OKC. At 1-year follow-up, the patient was comfortable and complete resolution of the radiolucent pathology was evident. Periodic examination is required because of the high rate of recurrence of OKC.
牙源性角化囊肿（OKC）是一种发育性、非炎性慢性囊肿，可为单房或多房。OKC的组织学特征具有诊断意义。一名41岁男性患者因34和35牙区域颊侧牙龈肿胀前来急诊评估。3周后进行切开引流，随后采用Puros同种异体骨移植和可吸收膜进行手术刮治和引导组织再生。切除组织的活检显示为OKC。在1年的随访中，患者情况良好，透射性病变完全消退。由于OKC复发率高，需要定期检查。
