Abstract：
BACKGROUND: A diagnosis of oral squamous cell carcinoma in adolescent patients is extremely rare. When an oral squamous cell carcinoma lesion arises near the teeth and/or periodontium, it can be easily misdiagnosed as an inflammatory condition of endodontic or periodontal origin.
METHODS: This is a case report of an otherwise healthy 14-year-old patient who was referred for endodontic evaluation and treatment of a soft-tissue swelling in the anterior maxilla.
RESULTS: The unexpected definitive diagnosis of invasive oral squamous cell carcinoma underscores the importance of proper diagnostic testing.
CONCLUSIONS: Accurate interpretation of pulp testing results, periapical and cone beam computed tomography imaging, timely biopsy, and prompt definitive treatment are critical when a lesion of nonodontogenic origin is suspected.

摘要：
背景：在青少年患者中诊断为口腔鳞状细胞癌（OSCC）极为罕见。当OSCC病变出现在牙齿和/或牙周组织附近时，它很容易被误诊为牙髓或牙周起源的炎症。
方法：这是一例健康的14岁患者的病例报告，该患者被转诊进行牙髓评估和治疗前上颌骨软组织肿胀。
结果：侵入性OSCC的意外明确诊断强调了正确诊断测试的重要性。
结论：准确解释纸浆测试结果，根尖周和锥束计算机断层扫描（CBCT）成像，及时活检,当怀疑非牙源性病变时，及时的明确治疗至关重要。
