Organ of Chievitz: Revisited

Mamata Kamat, Rudrayya Puranik, Shrinivas Vanaki, Varsha VK


Organ of Chievitz is a normal, epithelial structure of the oral cavity located in the most postero medial aspect of medial surface of ramus of mandible. It consists of benign epithelial islands or nests. In the current article, the location, embryology, histological appearance and diagnostic workup of JOC are revisited which is of special interest to the surgical pathologist for the oral cancer diagnosis, as they are in the potential of being misinterpreted as carcinoma or perineural invasion particularly on frozen sections. The purpose of the present article is to update the clinicians about the recent concepts and diagnostic pitfalls so that unnecessary investigations and overtreatment is prevented for the betterment of patients.
