ABSTRACT
BACKGROUND AND OBJECTIVES:
Epidermoid and dermoid cysts are benign cystic lesions, lined by ectodermal squamous epithelium. They are not common in the head and neck areas, which constitute ~7% of all cases of epidermoid and dermoid cysts. The aim of this study was to investigate the clinical characteristics of epidermoid and dermoid cysts that developed around the ear. SUBJECTS ANDMETHODS:
The clinical records were retrospectively reviewed for patients confirmed histologically as idiopathic epidermoid and dermoid cysts of the ear from January 2011 to December 2015.RESULTS:
Total 15 cases consisted of 14 epidermoid cysts and only 1 dermoid cyst. There were 11 males and 4 females (mean age of 37.8±16.8 years old). Right side was 7 cases and left was 8. The cyst was located at the lobule in 4 cases, at the ear canal in 4 cases, at the preauricular area in 4 cases, and at the postauricular area in 3 cases. In cases of epidermoid cysts, there was no significant difference in age, sex, and size according to the location. Patients with cysts on helix were younger than others.CONCLUSIONS:
This study demonstrated that most cutaneous cysts developing around the ear were epidermoid cysts and there was no site preference for occurrence of epidermoid cysts.
