초록
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.
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.
