Ameloblastic carcinoma is a rare odontogenic malignant tumor with the histologic features of both ameloblastoma and carcinoma. It occurs more frequently in the mandible than in the maxilla and it may appear or develop from a preexisting ameloblastoma or odontogenic cyst. Rapidly progressing, painful swelling is the most common symptom, and radiographically, it shows significant bone resorption and cortical perforation. This report described a case of ameloblastic carcinoma in a 45-year-old man who presented with swelling in the left mandible. The lesion showed combined features of benign findings, such as an expansile cortex with a distinct border, and malignant findings, such as a large exophytic mass with frank bone resorption. Excisional biopsy was performed and a final diagnosis of ameloblastic carcinoma was made.
成釉细胞癌是一种罕见的牙源性恶性肿瘤，具有成釉细胞瘤和癌的组织学特征。它在下颌骨比在上颌骨更常见，可能表现为或由先前存在的成釉细胞瘤或牙源性囊肿发展而来。快速进展的疼痛性肿胀是最常见的症状，在影像学上，它表现出明显的骨质吸收和皮质穿孔。本报告描述了一例45岁男性成釉细胞癌病例，该患者左下颌骨出现肿胀。病变显示出良性表现（如边界清晰的膨胀性皮质）和恶性表现（如伴有明显骨质吸收的大的外生性肿块）的综合特征。进行了切除活检，最终诊断为成釉细胞癌。
