Abstract

Neurofibroma is a relatively common neurogenic tumor originating from schwann cells or fibroblasts in peripheral nerve sheaths. It is classified as solitary or multiple. Solitary lesions are not usually associated with neurofibromatosis or von Recklinghausen's disease. We report a case of solitary neurofibroma occurred in the right external auditory canal (EAC) in a 30-year-old male who complained of progressive hearing loss and earfullness for 5 years. This diffuse painless mass displaced the auricle laterally and obstructed EAC completely. The lesion was partially excised by retroauricular approach and diagnosed as neurofibroma. This patient does not have any other evidences of neurofibromatosis. A complete excision in this case was not mandatory as malignant change is rare; moreover, it would require extensive resection of periauricular skin, subcutaneous tissue, cartilaginous ear canal and temporalis muscle, followed by reconstruction. We present the clinical characteristics and therapeutic methods of a solitary neurofibroma originating from EAC.
