Desmoplastic ameloblastoma (DA) is a rare variant of ameloblastoma (AM). The location of this lesion, its histology and radiological features differ from those of conventional AM. We report a case of DA in the canine / premolar region of the left maxilla of a 32-year-old woman and present a brief review of the literature. Radiographically, it had a mixed radiolucent / radiopaque appearance with ill-defined margins. Histologically, the tumor was characterized by extensive stromal desmoplasia and small tumor islands of odontogenic epithelium in the stroma, along with a few areas of reactive bone formation. The tumor was treated by partial maxillectomy and the patient was disease free after 1 year.
促结缔组织增生性成釉细胞瘤(DA)是成釉细胞瘤(AM)的一种罕见变异型。该病变的位置、组织学和放射学特征与传统的AM不同。我们报告一例32岁女性左上颌犬齿/前磨牙区域的DA病例,并对相关文献进行简要综述。影像学上,其表现为透射线/阻射线混合,边界不清。组织学上,肿瘤的特征是广泛的间质结缔组织增生,间质中有小的牙源性上皮肿瘤岛,伴有一些反应性骨形成区域。该肿瘤通过部分上颌骨切除术进行治疗,患者1年后无病生存。
