The desmoplastic variant of ameloblastoma is a rare form of ameloblastoma characterized by unique radiographic and histologic features. A 46-year-old female was referred to our hospital, complaining of swelling in the left upper lip area. Radiographic findings revealed an ill-defined multilocular lesion with a large cystic lesion and thick sclerotic trabeculae on the left anterior maxilla. After the patient underwent partial osteotomy, histologic analysis revealed a desmoplastic ameloblastoma with no evidence of a hybrid lesion or cyst formation. The radiographic findings in the present case were different from those described in previous case reports. These findings are of special importance due to the unfamiliar radiographic and histologic features of this lesion.
成釉细胞瘤的促结缔组织增生型是成釉细胞瘤的一种罕见形式，具有独特的影像学和组织学特征。一名46岁女性因左上唇区域肿胀被转诊至我院。影像学检查发现左上前颌骨有一个边界不清的多房性病变，伴有一个大的囊性病变和粗大的硬化性小梁。患者接受部分截骨术后，组织学分析显示为促结缔组织增生型成釉细胞瘤，无混合性病变或囊肿形成的证据。本病例的影像学表现与既往病例报告中描述的不同。由于该病变不常见的影像学和组织学特征，这些发现具有特殊重要性。
