Invasive keratinizing squamous cell carcinoma of the left external auricular canal and the middle ear - case report.

The rather low incidence of auricular neoplasms irrespective of localization is likely to cause confusion of diagnosis with the more frequent benign ear pathology. Because of this, the elapsed time until confirmation of the diagnosis facilitates the evolution of the disease to the detriment of the patient's health. The diagnosis of an ear neoplasm can hide under the ordinary appearance of external otitis, chronic otorrhea or episodes of various types of ear pain. Evolution of such a malignant pathology is quite rapid and highly aggressive locoregional complications are the subject of discussions regarding the interpretation of the results of paraclinical tests and the medical-surgical treatment approach that must take into account the histological structure, the size of the tumor, and the invasion of neighboring tissue.
