title: Sudoriferous cyst of the orbit of adult origin after trauma.
abstract: A rare case of sudoriferous cyst of the orbit occurring in an adult, who had facial trauma, is reported. Several factors suggest its adult onset. The only other case reported in an adult is of presumed childhood origin. Very few congenital cases have been reported. A 65-year-old lady presented with recent onset of left-sided ptosis and a painless mass below the left supraorbital margin. The patient had traumatic ptosis after a road traffic accident 13 years ago. The ptosis was surgically repaired, which resulted in symmetrical palpebral apertures. Computed tomographic scan revealed a well-defined cystic mass in the anterior orbit. The mass was removed in toto by anterior orbitotomy. Histopathological examination revealed a single cyst lined by double-layered cuboidal epithelium in some areas and transitional epithelium at others. A periodic acid Schiff (PAS) positive, diastase-resistant glycocalyx lined the inner epithelium. Apical snouting suggested an apocrine nature. This confirmed a diagnosis of sudoriferous cyst.
