Abstract

It is widely accepted that radicular cysts (apical periodontal cysts) are commonly lined with stratified squamous epithelium without keratin formation. However, we identified a case of maxillary radicular cyst with remarkable keratinization and atypical proliferation of the lining epithelium among the 207 radicular cyst cases seen at our department. Histopathological and clinical findings of these cysts were reviewed.

摘要

普遍认为，根端囊肿（根尖牙周囊肿）通常内衬无角化形成的复层鳞状上皮。然而，在我们科室所见的207例根端囊肿病例中，我们发现了1例上颌根端囊肿，其内衬上皮有明显角化及非典型增生。对这些囊肿的组织病理学和临床发现进行了回顾。
