牙源性恶性肿瘤的病理学诊断

Pathological diagnosis of malignant odontogenic tumors

颌骨内的胚胎性成牙组织常为牙源性肿瘤的组织来源。因此,颌骨是人类骨骼中最好发上皮性肿瘤的部位,并且常伴有牙体样组织形成。牙源性恶性肿瘤发病率低,缺乏临床及病理诊断经验,需与多种来源类型的肿瘤鉴别诊断,这些侵袭性病损具有较高的复发倾向,生物学行为等方面具有特殊性。本文着重讨论牙源性恶性肿瘤的病理学诊断。

The jaw bones are the most common sites for epithelial tumors in the human skeleton with dysplastic dentin,most of which have all odontogenic origin.Malignant odontogenic tumours have a low incidence,and for lack of clinical and pathological diagnostic experience,it should be differentiated from the multiple sources types of tumors. The aggressive malignant odontogenic tumours often produce marked facial deformity and tend to recur after insufficient surgery. This article is intended to discuss the pathological diagnosis of malignant odontogenic tumors.
