title: Huge intradiploic epidermoid cyst.
abstract: A 60-year-old man presented with an occipital mass under the scalp and complained of headache, nausea, and dizziness. Magnetic resonance imaging showed a well-defined mass in the occipital scalp extending from the scalp through the cranium and several centimetres into the posterior fossa. There were well-defined margins in the deep portion and the mass was totally removed. Histological examination showed that the cystic structure was lined by squamous epithelium containing laminated keratin material. The pathological findings were consistent with the diagnosis of an epidermoid cyst. The patient was discharged free of symptoms.
