Giant intradiploic epidermoid cysts of the skull. A report of eight cases.

Giant intradiploic epidermoid cyst of the skull is a rare tumour. Only a small number of cases have been reported. Over a 16-year period, we treated eight cases of giant intradiploic epidermoid cyst of the skull. All cases were between 19 and 45 years of age, except one aged of 61 years. Five cases presented with local swellings, three patients came with infection and one had an extradural abscess. All the patients were operated upon after adequate preoperative care. Patients with infection required appropriate antibiotics. Total or near total excision was carried out in all. One patient developed postoperative infection. So for those have been no recurrences. This appears to be the largest series of giant intradiploic epidermoid cyst of the skull so far reported.
