Dermoid cysts (DC) of the head and neck are rare congenital anomalies derived from entrapment of ectodermal cells at lines of fusion in the embryo into mesoderm. We describe a 22-years-old female with an unusual presentation of DC in the subcutaneous tissue of the retro-auricular region, confirmed by pathological examination of the surgically removed specimen. A DC in this region is rare and may be misdiagnosed as a retroauricular lymph node. Complete excision of the lesion must be achieved with pathology study to confirm diagnosis.
