The orthokeratinized odontogenic cyst is a relatively rare developmental odontogenic cyst of the jaws that occurs predominantly in males between the third and fourth decades. According to the 2005 World Health Organization's classification, orthokeratinized odontogenic cyst is not a part of the keratocystic odontogenic tumor spectrum. We present a case of a 41-year-old male with a history of remarkable lingual expansion in the anterior part of the maxilla since last year with rapid growth in the last three months as a unilocular well-defined radiolucent lesion extending from maxillary left central incisor to the right second premolar. Orthokeratinized odontogenic cyst is a specific type of keratinized odontogenic cysts which is completely different from keratocystic odontogenic tumor from the viewpoint of the clinical and pathological features.
正角化型牙源性囊肿是一种相对罕见的颌骨发育性牙源性囊肿，主要发生于30至40岁的男性。根据2005年世界卫生组织的分类，正角化型牙源性囊肿不属于牙源性角化囊性肿瘤谱系。我们报告一例41岁男性病例，自去年以来上颌前部出现明显的舌侧膨隆，近三个月迅速生长，表现为一单房、边界清晰的透射性病变，从左上颌中切牙延伸至右第二前磨牙。正角化型牙源性囊肿是角化型牙源性囊肿的一种特殊类型，从临床和病理特征来看，它与牙源性角化囊性肿瘤完全不同。
