Eccrine Hidrocystoma in External Auditory Canal / 대한이비인후과학회지

ABSTRACT

Hidrocystomas, eccrine or apocrine are rare ductal cystic benign lesions of the sweat gland. These uncommon cystic lesions are extremely rare in the external ear. Here, we discuss the clinical features and management of eccrine hydrocystoma in the external ear by describing the clinical, radiographic, pathologic features and management of an external auditory canal eccrine hidrocystoma in a 73-year-old Korean man. To the best of our knowledge, this tumor has not been reported previously in this site. Five month after surgery, there has been no evidence of local recurrence.
