Nodular fasciitis of the external auditory canal: Clinical case report and review of the literature

Nodular fasciitis is a benign reactive soft tissue tumor arising from fibroblasts and myofibroblasts. Its incidence is low and misdiagnosis is frequent especially for malignant lesions. This can lead to inappropriate and unnecessary invasive treatment. Nodular fasciitis of the external auditory canal is extremely rare. So far, around fifteen cases have been reported. We present here the case of a 90-year-old patient with nodular fasciitis of the right external auditory canal. The lesion extends anteriorly for 6.5 cm and reaches the posterior wall of the maxillary sinus. To our knowledge, this is the first case in the literature of an external auditory canal nodular fasciitis presenting as an inflammatory ear polyp with such a wide extension.
