Gingival cysts of the adult (GCAs) are rare developmental soft tissue cysts usually found on the facial attached gingiva. Documented cases on the lingual aspect are extremely uncommon. This report details a lingual GCA along with distinguishing characteristics of this lesion.
The patient, a 37-year-old female, presented with a firm, round-shaped, bluish swelling on the lingual gingiva in the interproximal area between teeth #21 and #22. Radiographs revealed a circular radiolucency at the osseous crest. Surgical exploration showed cystic-appearing tissue with accompanying bone resorption. Histologic examination, along with clinical presentation, confirmed a diagnosis of gingival cyst. Healing was uneventful with no evidence of recurrence at a 5-month recall.
A GCA is usually of odontogenic origin and occurs typically in the attached gingiva of the mandibular premolar region. Occasionally, it demonstrates radiographic evidence of bone loss from pressure resorption. Its more frequent intraosseous counterpart, the lateral periodontal cyst, shares histopathologic characteristics with the GCA. These findings underscore the importance in establishing a definitive diagnosis.
成人牙龈囊肿（GCA）是罕见的发育性软组织囊肿，通常见于面部附着龈。舌侧的病例极为罕见。本报告详细介绍了一例舌侧GCA及其该病变的鉴别特征。
患者为一名37岁女性，在21号和22号牙之间的邻间隙舌侧牙龈处出现一个质地坚硬、圆形、蓝色的肿胀。X线片显示牙槽嵴处有圆形透射区。手术探查显示为囊肿样组织，并伴有骨质吸收。组织学检查结合临床表现确诊为牙龈囊肿。5个月复查时愈合良好，无复发迹象。
GCA通常起源于牙源性，典型发生于下颌前磨牙区的附着龈。偶尔，它会显示因压力吸收导致骨质丧失的影像学证据。其更常见的骨内对应物，即侧向牙周囊肿，与GCA具有相同的组织病理学特征。这些发现强调了明确诊断的重要性。
