自体移植骨中复发性成釉细胞瘤2例报告及文献复习

报告2例因右下颌骨成釉细胞瘤行右侧下颌骨部分切除或半侧下颌骨切除术后即刻分别行自体髂骨或肋骨移植的病例,2例病例在行X线检查时分别于术后16年和14年在移植骨中发现成釉细胞瘤复发。例1行术中冷冻切片活检,病理学诊断为滤泡型成釉细胞瘤。结合本组2例病例,并对已发表的文献进行复习,认为成釉细胞瘤发生在肿瘤切除植骨后的骨中属于罕见病例,应对其复发机制进行深入研究。

Recurrences of ameloblastoma in bone grafts: Report of two cases and literature review

Two cases of recurrence of an ameloblastoma in autogenous rib or iliac bone graft many years after the initial operation for a mandibular ameloblastoma with evidence of soft or hard tissue invasion were presented. A review of the literature disclosed only 13 cases of recurrence of ameloblastoma in bone grafts. The initial operation in the 2 cases presented was hemimandibulectomy followed by autogenous rib or iliac bone graft. Sixteen years or fourteen years after surgery there was clinical and radiographic signs of recurrence. It was concluded that extensive resection including bone as well as adjacent soft tissues is critical because recurrence seems to come from the soft tissues, especially from the adjacent periosteum or bone.
