A 10-year-old girl with ocular complications of Stevens-Johnson syndrome developed a large superior orbital cyst above the right eye. When the cyst recurred after needle aspiration, it was removed surgically and the superior conjunctival fornix was replaced with a buccal mucous membrane graft. Histopathologically the lesion proved to be a clear cyst lined by nonkeratinizing epithelium compatible with conjunctival epithelium with rare goblet cells. The patient did well postoperatively. An orbital cyst is a rare ocular complication of the Stevens-Johnson syndrome.
