Epidermal inclusion cyst of external auditory canal– A common lesion at a rare site diagnosed by FNAC

Epidermal inclusion cyst (EIC) is a benign condition that occurs rarely in the External auditory canal. EIC refers to cysts that result from the proliferation and implantation of epidermal elements within a circumscribed space in the dermis. Epidermal cysts occur anywhere in the body and are more common on the face, trunk, neck, extremities and scalp. The occurrence of EIC in the External auditory canal is rare. Lesions of such nature are frequently thought to be lesions like polyp, haematoma, haemangioma and are not included as one of the main differential diagnoses of lesions in External auditory canal. We report case of EIC of the External auditory canal in 4 years old child so that it should be kept as differential diagnosis of lumps in external auditory canal. The diagnosis was made on FNAC which is simple, OPD procedure and does not require any anaesthesia underlining the importance of FNAC in Ear lesions.
