Solitary neurofibroma in the external auditory canal

Significance Statement: Neurofibromas, derived from perineural cells, are usually benign in the nervous system. Although neurofibromas are common in the head and neck, they rarely affect the external auditory canal (EAC), and few cases have been reported. We describe a case of a solitary EAC neurofibroma with otoscopy, radiological imaging, a surgical approach, and an uneventful outcome.

Solitary neurofibroma of the right lateral wall of the oropharynx

Solitary neurofibroma of the oropharynx is extremely rare. Imaging explorations may be necessary, but the diagnostic certainty is pathological. We report a case of benign tumour of the oropharynx in a 25-year-old woman who was seen for a consultation with dysphagia, a change in voice and dyspnea in the supine position. The excision was performed under general anaesthesia with orotracheal intubation via the oropharyngeal route. Pathological examination of the surgical specimen revealed neurofibroma. Although rare, solitary neurofibroma of the oropharynx should be considered in any benign tumour in the area.

A CASE OF SOLITARY NEUROFIBROMA OVER THE PALM

Neurobromas are benign tumours, that are slow growing over the nerve sheaths composed of schwann cells , perineural cells and broblasts. Nuerobromas are common neurogenic tumors of the skin. A neurobroma can be diagnosed by clinical and histologic examinations.
