Bilateral external ear canal osteomas - discussion on a clinical case.

Osteomas of the external ear are uncommon benign tumors that need to be differentiated from the external ear canal exostoses, bony proliferations that are linked mainly to cold-water exposure. Clinical manifestations vary from no symptoms to recurrent local infections and external ear cholesteatoma. presenting a rare case that we did not find described in the published literature. A patient with multiple long-term asymptomatic osteomas of both external ear canals presented to our department. Data recorded from the patient's medical record was reviewed and analyzed. Surgery was performed and histology confirmed the presumptive diagnosis. There was a discrepancy between the local severity of the disease, with a complete obstruction of his ear canals, and the long-term disease-free status of the patient. We hypothesized about the etiology of these multiple bilateral osteomas of the EAC, in light of the clinical and surgical findings.
