Familial frontonasal dermoid cysts

✓ A family group, comprised of father and all three children, had frontonasal dermoid cysts. Clinical features and x-ray findings are discussed, and the similarity to a slow-growing intracranial space-occupying lesion is emphasized. Plain x-ray films may show a widened nasal septum, and contrast radiology will help outline an avascular mass arising from the cribriform plate. Resection utilizing a synchronous nasal and frontal operation proved effective.
