title: Giant epidermal inclusion facial cyst.
abstract: Epidermal inclusion cyst is one of the most common subcutaneous tumors, and its size normally varies from 1 to 5 cm in diameter. Only few giant epidermal inclusion cysts have been reported in the literature, and giant epidermal cyst of the face has never been reported. An 83-year-old woman visited our hospital for a huge mass on the right side of her face extending to the temporal area, creating deformity of her right ear. The mass was 15 × 15 × 8 cm(3) with soft, cystic nature. It has developed since 20 years ago with no known etiology. Computed tomography scan was obtained for preoperative evaluation, which showed a 15 × 15 × 7-cm(3) huge, lobulated, and septated mass with no underlying bone or brain involvement. We performed complete excision sand biopsy. On histologic examination, the final diagnosis of epidermal inclusion cyst was made. Keratotic material was within the cyst, and the cystic wall was composed of lamellate keratin. Follow-up period was 10 months, and no signs of recurrence were seen. The patient was satisfied with the improvement of her facial appearance. We have observed a case of giant epidermal inclusion cyst of the face, which has never been reported, and present this case with a brief review of literature.
