Abstract
|
|
|
|
Cystic tumors arising from cystic dilatation of the excretory duct of the eccrine sweat glands or eccrine hidrocys- toma are extremely rare in the external auditory canal. We describe a rare case of an eccrine hidrocystoma, con- fined to the external auditory canal in an adult patient. The lesion was completely excised via transcanal endo- scopic approach. The diagnosis of eccrine hidrocystoma was made based on pathologic findings. Eccrine hidrocystoma should be considered as possible differential diagnoses of mass lesions in the external auditory canal.
