periocular dermoid cysts: common sites in referral cases in an iranian population

purpose : to review periocular dermoid cysts to determine distribution of demographic factors, and tumor location methods : in this retrospective, observational case series in a tertiary-care hospital, we reviewed all cases of histopathologically verified periocular dermoid cysts at our institution between 2003 and 2011. the study endpoints included: age, gender, and tumor location. results : two hundred and thirty-nine patients entered the study whose mean age at the time of surgery was 11.8 years (range 6 months-48 years, 54% male). the frequencies of dermoid cysts in supranasal and supratemporal locations were fairly equal (46% and 49.4% respectively). conclusion : in contrast to previous reports, we reported fairly equal frequency of supranasal and supratemporal locations in an iranian group of patients.   iranian journal of ophthalmology 201325(4):309-312 © 2013 by the iranian society of ophthalmology
