Cervical Chondrocutaneous Branchial Remnant: A Case Report and Review of the Literature

Abstract

Cervical chondrocutaneous branchial remnant is a rare congenital developmental anomaly typically located on the lateral neck. Histologically, it has the appearance of an accessory tragus demonstrating a central cartilaginous core with surrounding fibrosis located in the subcutaneous tissue. The condition has been associated with a variety of congenital anomalies, particularly involving the auditory, cardiovascular, and visual systems. Given that research-based evidence related to cervical chondrocutaneous branchial remnant in dermatology literature is sparse, we present this case to raise more awareness about this entity among dermatopathologists and review the different histopathologic presentations and possible associated anomalies.
