Abstract:

Angiofibromas are rare benign fibrovascular tumors typically found in the nasopharynx. Extra-nasopharyngeal angiofibromas are even more uncommon, with limited reports of their occurrence in the external auditory canal (EAC). We present a case of an angiofibroma located in the left EAC in a 33-year-old woman who presented with the gradual onset of multiple nodules on the pinna and EAC, along with left-sided otalgia for 6 months. Clinical examination revealed angiomatous papulo-nodules, the largest measuring 1 cm. Histopathological analysis confirmed angiofibroma. Preoperative audiometry showed moderate conductive hearing loss in the left ear. A CT scan revealed polypoid mucosal thickening in both the bony and cartilaginous EAC without bone erosion. Given the clinical and radiological findings, the patient first underwent an incomplete excision of the lesions on the pinna. Subsequently, she received external radiation therapy using intensity-modulated radiation therapy (IMRT), receiving a total dose of 50 Gray in 25 fractions. The patient experienced grade 1 radiodermatitis, which resolved without complications. Follow-up CT at 6 months showed regression of the polyps and post-therapy changes in the pinna. The patient remains stable with no further progression.
