Squamous Cell Carcinoma of External Auditory Canal

Abstract

Squamous cell carcinoma of the external auditory canal has a low incidence, with a mean age of presentation of 40-60 years old. The characteristic clinical presentation is an occupational EAC lesion that is accompanied by chronic otalgia, purulent/hematic otorrhea and conductive hearing loss. We reported the case of a 75-years old female patient with one year of intermittent right ear purulent/ hematic otorrhea, and ipsilateral hearing loss, so she decided to search an otolaryngological evaluation, at exploration of the patient, she had a smooth, spherical, whitish lesion with epithelial features and no evaluable pedicle, that obstructed the 90% of the right EAC at the inner third, rest of the evaluation without alteration of the mandibular dynamics, cylindrical neck without palpable masses, mobile central trachea with crepitus, an incisional biopsy of the right EAC tumor was performed and the anatomopatologic reported was an in situ squamous cell carcinoma.
