Odontogenic keratocysts (OKCs) are benign cysts arising from the dental lamina and its remnants. They are most commonly located in the posterior body and the ramus of the mandible. The diagnosis of peripheral OKCs (other than intraosseous) are extremely rare and the current literature is limited. The most common location is the gingiva, but mucosal, epidermal, and even intramuscular sites have also been described. Currently 15 cases have been described. The origin and nature of peripheral OKC still remains controversial. The differential diagnosis includes gingival cyst, mucoceles and epidermoid cyst. Soft tissue OKCs have a lower rate of recurrences; 12,5% vs. 62% in intraosseus OKCs. We report a case of a 58-year-old woman with a peripheral OKC, located in the left masticatory space. We performed a review of the existing literature on peripheral odontogenic keratocysts. Odontogenic keratocysts (OKCs), peripheral keratocyst, mandibular cyst.
牙源性角化囊肿（OKCs）是起源于牙板及其残余物的良性囊肿。它们最常见于下颌骨体后部和下颌支。外周性OKCs（非骨内型）的诊断极为罕见，目前的文献有限。最常见的部位是牙龈，但也有黏膜、表皮甚至肌肉内的病例报道。目前已报道15例。外周性OKC的起源和性质仍存在争议。鉴别诊断包括牙龈囊肿、黏液囊肿和表皮样囊肿。软组织OKCs的复发率较低；骨内型OKCs的复发率为62%，而软组织OKCs的复发率为12.5%。我们报告一例58岁女性，其外周性OKC位于左侧咀嚼间隙。我们对现有的外周性牙源性角化囊肿文献进行了综述。牙源性角化囊肿（OKCs）、外周性角化囊肿、下颌囊肿。
