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.
