Ameloblastomas are rare odontogenic epithelial tumors that occur mainly in the mandible. Despite their benign histologic appearance, they are locally aggressive with a high recurrence rate. However, a metastasizing ameloblastoma has been rarely reported. According to the current World Health Organization classification system, the definitive diagnosis of metastasizing ameloblastoma can only be carried out in retrospect, after the event of metastasis. This case report describes a patient with metastatic pulmonary ameloblastoma, 17 years after the surgical excision of an odontogenic tumor, preoperatively misdiagnosed as primary squamous cell carcinoma.
成釉细胞瘤是一种罕见的牙源性上皮肿瘤，主要发生在下颌骨。尽管其组织学表现为良性，但具有局部侵袭性且复发率高。然而，转移性成釉细胞瘤鲜有报道。根据目前的世界卫生组织分类系统，转移性成釉细胞瘤的确诊只能在转移事件发生后进行回顾性诊断。本病例报告描述了一名患者，在牙源性肿瘤手术切除17年后发生了肺转移性成釉细胞瘤，术前被误诊为原发性鳞状细胞癌。
