Abstract

The direct transformation of an ameloblastic fibroma into a fibrosarcoma in a 16-year-old Caucasian male is reported. Although no ameloblastic epithelium was found in the recurrent tumor, the odontogenic origin of the fibrosarcoma was evident. The ameloblastic fibrosarcoma and the fibrosarcoma of identical odontogenic origin represent an entity which should be distinguished from conventional fibrosarcoma as these tumors demonstrate different clinical behaviors.

摘要

据报道，一名16岁的高加索男性患者，其成釉细胞纤维瘤直接转变为纤维肉瘤。尽管在复发性肿瘤中未发现成釉细胞上皮，但纤维肉瘤的牙源性起源是明显的。具有相同牙源性起源的成釉细胞纤维肉瘤和纤维肉瘤代表一种实体，应与传统纤维肉瘤区分开来，因为这些肿瘤表现出不同的临床行为。
