通过18例牙源性良、恶性造釉细胞瘤的超微结构观察,发现肿瘤细胞岛的中心部细胞分化程度不一,呈现2种形态特征,据此将其分为二型。本文着重观察二型细胞在良、恶性造釉细胞瘤中的分布特点,并结合生物学行为进行了讨论。
Through the ultrastructural observation of 18 cases of benign and malignant ameloblastomas of odontogenic type, it was found that the cells in the central part of the tumor cell islands had different degrees of differentiation, showing two morphological characteristics, and were accordingly divided into two types. This article focuses on the observation of the distribution of type 2 cells in benign and malignant ameloblastomas and discusses their biological behavior.
