Fibroepithelial Polyp of the External Auditory Canal Extending to the Eustachian Tube: A Rare Clinical Entity.

Fibroepithelial polyps are benign mesodermal lesions that are an uncommon occurrence within the external auditory canal and the middle ear. The present case involves a 39-year-old male patient who has been experiencing hearing loss and intermittent ear discharge for a period of 10 years. Otoscopic examination revealed a smooth mass that completely filled the external auditory canal. A thorough analysis of the computed tomography results revealed the presence of soft-tissue density extending to the middle ear and Eustachian tube, with no evidence of bone destruction. Noncontrast magnetic resonance imaging showed a T1 hypointense signal, a T2 hyperintense signal, and no diffusion restriction. This case exemplifies an exceedingly rare condition involving a substantial portion of the temporal bone. It is essential to be aware of this condition to prevent misdiagnosis as a malignant lesion. An accurate diagnosis depends on a radiological-histopathological correlation.
