Ameloblastic fibroma is an uncommon, benign, mixed odontogenic tumor characterized by the presence of both epithelial and mesenchymal components, without the formation of hard tissue. It constitutes approximately 1.5%-4.5% of all odontogenic tumors and predominantly affects the posterior mandible. Most cases are observed in individuals under 22 years of age, with a slight predilection for males. The initial presentation typically involves a painless, slow-growing mass, often discovered incidentally during routine radiographic examinations. This lesion carries a risk of recurrence and potential for malignant transformation. We present a case of an 8-year-old female child who presented with a painless swelling in the right posterior mandibular region for 6 months, which was histologically characterized by dentinoid formation.
成釉细胞纤维瘤是一种罕见的良性混合性牙源性肿瘤,其特征是同时存在上皮和间充质成分,且不形成硬组织。它约占所有牙源性肿瘤的1.5%-4.5%,主要累及下颌骨后部。大多数病例见于22岁以下个体,男性略多。最初表现通常为无痛、生长缓慢的肿块,常在常规影像学检查时偶然发现。该病变有复发风险和恶变潜能。我们报告一例8岁女童,其右下颌后区无痛性肿胀6个月,组织学特征为类牙本质形成。
