Radicular Cysts and limbal dermoid in Treacher Collins syndrome

Abstract

Treacher Collins syndrome (TCS, OMIM 154500) [1] is a rare autosomal dominant disorder of the craniofacial region and structures derived from first and second branchial arches such as the ears, eyelids, maxilla and mandible are affected in this syndrome. An 18 year old female presented with the dysmorphic features of the face, partial anodontia, macroglossia, malocclusion, cleft palate, coloboma, limbal dermoid, deformity of the pinna, partial hearing loss (absence of right ear canal), malar hypoplasia and radicular cyst in the left body of mandible as well as in the maxillary posterior region. In this case, though radicular cysts are incidental findings, the limbal dermoid reported here is a rare manifestation in TCS.
