Choristoma is a mass of tissue with normal histology similar to a part of the body that is different from the one in which it is located. It differs from the hamartomatous group of pathology which is normal tissue, but disorganized, found in an abnormal location. Documentation of the occurrence of osseous choristoma lesions in the oral cavity has been scarce, and most of the cases have been reported in the tongue. It is very seldom to arise from the interdental gingiva. Indeed, choristoma is considered a developmental anomaly, involving younger individuals, although many cases among older adults have been reported. The differential diagnoses include cartilaginous metaplasia, pleomorphic adenoma, salivary gland tissue, and the lesions of inflammatory or traumatic origin that may give rise to hamartomas in the oral cavity. In this case report, we present a case of osseous choristoma arising from the mandibular, posterior buccal gingiva in a young female patient.
迷离瘤是一团组织，其组织学正常，类似于身体中与其所在部位不同的某个部位的组织。它与错构瘤性病变不同，错构瘤性病变是正常组织，但结构紊乱，出现在异常位置。口腔内骨迷离瘤病变的发生记录很少，大多数病例报告发生在舌部。很少起源于齿间牙龈。实际上，迷离瘤被认为是一种发育异常，多见于年轻人，尽管也有许多老年患者的病例报告。鉴别诊断包括软骨化生、多形性腺瘤、涎腺组织以及可能在口腔内引起错构瘤的炎症或创伤性病变。在本病例报告中，我们呈现了一例年轻女性患者下颌后颊侧牙龈发生的骨迷离瘤病例。
