Ameloblastomas are locally aggressive jaw tumors with a high propensity for recurrence that are believed to arise from remnants of odontogenic epithelium, lining of odontogenic cysts and basal layer of overlying oral mucosa. They can occur in either the maxilla or mandible at nearly any age but most frequently are discovered as a painless expansion in the mandible of patients in their 20s-40s. Histopathologically, the follicular and plexiform patterns are the most common. When extensive squamous metaplasia, often associated with keratin formation occurs in central portions of the epithelial islands of follicular ameloblastoma, the term acanthomatous is sometimes applied. Here we present a case of acanthomatous ameloblastoma in a 20 year old patient. Key words:Ameloblastoma, Aacanthomatous, Mandibular Tumors.

成釉细胞瘤是具有高度复发倾向的局部侵袭性颌骨肿瘤，被认为起源于牙源性上皮残余、牙源性囊肿衬里及覆盖其上的口腔黏膜基底层。它们几乎可在任何年龄发生于上颌骨或下颌骨，但最常见于20至40岁患者的下颌骨无痛性膨隆时被发现。组织病理学上，滤泡型和丛状型最为常见。当滤泡型成釉细胞瘤上皮岛中央出现广泛的鳞状化生（常伴有角蛋白形成）时，有时会使用棘皮瘤型这一术语。在此，我们报告一例20岁患者的棘皮瘤型成釉细胞瘤。关键词：成釉细胞瘤；棘皮瘤型；下颌肿瘤。如何引用本文：Geeta Singh, Rashmi Agarwal, Vimlesh Kumar, Deepak Passi。棘皮瘤型成釉细胞瘤——一例报告。《国际口腔健康杂志》2013年；5(2):60 - 64。
