Ameloblastic carcinoma is a rare odontogenic tumor exhibiting histologic evidence of malignancy in the primary or recurrent tumor, regardless of whether it has metastasized or not. Most ameloblastic carcinomas are presumed to have arisen de novo, with few cases of malignant transformation of ameloblastoma being apparent. A case is reported of a 21-year-old caucasian female with ameloblastic carcinoma in the left angulus area of the mandible resembling an odontogenic cyst in the panoramic radiograph. In addition to the panoramic radiograph, computerized tomography (CT) and magnetic resonance (MR) images were taken preoperatively. This report demonstrates that CT or MR examinations may be crucial in differentiating odontogenic tumors from cysts.
成釉细胞癌是一种罕见的牙源性肿瘤，无论其是否发生转移，在原发肿瘤或复发肿瘤中均有组织学恶性证据。大多数成釉细胞癌被认为是原发的，很少有成釉细胞瘤恶变的病例。本文报道了一例21岁的白种女性，在下颌左角区患有成釉细胞癌，全景片上类似牙源性囊肿。除全景片外，术前还进行了计算机断层扫描（CT）和磁共振（MR）成像。本报告表明，CT或MR检查对于鉴别牙源性肿瘤和囊肿可能至关重要。
