Abstract
Dermoid cysts of the head and neck are rare lesions. An unusual dermoid cyst in the subcutaneous tissue of the mastoid region is easily confused with lymph node abnormalities; therefore, diagnosis and treatment are often challenging. We describe a 22-year-old male with an unusual dermoid cyst in the subcutaneous tissue of the mastoid region whose only complaint was a retroauricular lump, which was similar to an intumescent retroauricular lymph node. Final diagnosis was confirmed by pathological examination of the surgically removed specimen. A dermoid cyst in the subcutaneous tissue of the mastoid region is rare and may be misdiagnosed as a retroauricular lymph node. A lump may be the only presenting symptom without hearing loss and vertigo complaints. Complete excision of the tumor must be ensured and pathological analysis is important for the diagnosis.
