青少年上颌骨骨化性纤维瘤临床病理特征分析

Analysis of Clinicopathological Characterstics of Ossifying Fibroma of Juvenile Maxillary

目的探讨青少年上颌骨骨化性纤维瘤的临床病理特征。方法回顾性分析1例上颌骨骨化性纤维瘤的临床、影像学、病理形态学特征及鉴别诊断,并结合文献复习。结果镜下见肿瘤由丰富的较一致的纤维性梭形细胞组成,呈席纹状生长,是1种少见的良性纤维性骨性肿瘤。结论青少年上颌骨骨化性纤维瘤与普通性骨化性纤维瘤不同,临床上呈一种进展性生长模式,可以出现侵袭性生长及广泛骨皮质破坏,切除不完全时容易复发。

Objective To investigate the clinicopathological characterstics of ossifying fibroma of juvenile maxillary.Methods Clinical,radiographical,and pathological features and differential diagnosis of 1 case of ossifying fibroma were retrospectively analyzed,and a review of the literature on the subject was provided. Results Microcopically,the tumor contained a uniformly cellular fibrous spindle cell growth arranged in a whorled or matted pattern. It is a rare benign fibro-osseous neoplasm.Conclusion Ossifying fibroma of juvenile maxillary is a benign slow growing tumor which may behave in a non-predictable aggressive fashion and has high recurrence. Local recurrence is more likely due to incomplete removal in a lesion.
