摘要

鳞状细胞癌（SCC）很少起源于牙源性囊肿的上皮内膜，被称为原发性骨内鳞状细胞癌（PISCC），主要起源于长期存在的牙源性囊肿。牙源性囊肿的恶性改变发生率在0.3 % ~ 3 %之间。大约25% %来自牙源性囊肿的PISCC具有发育不良的内衬。本报告旨在描述一个不寻常的发生在牙源性角化囊肿上皮内膜的发育异常变化，该囊肿最初被诊断为牙源性角化囊肿。

Dysplastic epithelial changes in an odontogenic cyst with keratinization: A rare occurrence

Squamous cell carcinoma (SCC) rarely arises from the epithelial lining of odontogenic cysts, and is referred to as primary intraosseous squamous cell carcinoma (PISCC), which mainly originates from long-standing odontogenic cysts. The incidence of malignant changes in odontogenic cysts is between 0.3 % and 3 %. Approximately 25 % of PISCC derived from odontogenic cysts had a dysplastic lining. The report aims to describe an unusual occurrence of dysplastic changes in the epithelial lining of an odontogenic cyst with keratinization that was primarily diagnosed as an odontogenic keratocyst.
