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.
