Abstract

  Pleomorphic adenoma of the external ear canal, also known as chondroid syringoma is a rare benign space-occupying lesion in this anatomical site. We report a rare case of primary pleomorphic adenoma of the RT external auditory canal in a healthy 31-year-old male patient and discuss its clinical presentation, diagnosis, imaging study and treatment options.

  A 31-year-old male presented with ongoing right ear fullness and hearing deterioration over a 2 -year period. He denied any ear drainage. A firm rubbery mass around the outer 3rd part of the external auditory canal was noted on physical examination. High resolution CT scan of the temporal bone showed tumor mass with no evidence of bone destruction and without evident involvement of the tympanic membrane, MRI demonstrates clear separation between parotid gland and the lesion.

  The patient underwent surgical excision with retroarticular approach for complete resection of the tumor and the entire skin of the external auditory canal with wide canaloplasty. Final histology and immunohistochemistry confirmed a diagnosis of primary ceruminous pleomorphic adenoma of the external auditory canal, and three months following the surgery, patient is free of any recurrent disease or hearing loss.
