Periappendiceal Dermoid: A Rare Cause of Right Lower Quadrant Pain

Abstract

Dermoids are mature teratomas lined with a stratified squamous epithelium. They are known to present anywhere in the body, mostly with minimal or no associated symptoms. The authors present the case of a 44-year-old man who presented with an acute abdomen suggestive of appendiceal disease. On surgical exploration, the patient was found to have an inflamed cystic lesion in the mesoappendix that was resected and diagnosed as a dermoid cyst on pathological examination. This is the seventh case in the literature of a periappendiceal dermoid, but the first that presents in such a manner. This report is presented because of its important clinical applications for the general surgeon.
