METHODS: A case report presenting an 11-year-old male child with a swelling in the posterior mandible. Radiographic examination revealed a multilocular lesion with mixed radiodensity related to the impacted lower left second premolar tooth. Incisional biopsy was done, and microscopic examination revealed cords and nests of odontogenic follicles lined by ameloblast-like cells and central stellate reticulum-like cells in the primitive ecto-mesenchymal stroma with areas of dentinoid material and osteodentin. The diagnosis was ameloblastic fibro-dentinoma. Surgical excision of the lesion was done, and the patient was followed up for 1 year without evidence of recurrence.
CONCLUSIONS: Reporting such a rare entity clarifies the debate about its nature and the importance of early diagnosis of lesions that are associated with unerupted teeth showing how it is effective in early management and prognosis.
方法:一例11岁男性儿童下颌骨后部肿胀的病例报告。影像学检查显示多房性病变,与受影响的左下第二前磨牙相关的放射密度混合。做了切开活检,显微镜检查显示,在原始的外间充质基质中,成釉细胞样细胞和中央星状网样细胞排列的牙源性卵泡的索和巢,并带有类牙质材料和骨凝蛋白。诊断为成釉细胞纤维性牙本质瘤。手术切除了病灶,患者随访1年,无复发证据.
结论:报道这种罕见的实体澄清了关于其性质和早期诊断与未萌出牙齿相关的病变的重要性的争论,表明其在早期治疗和预后中的有效性。
