Myofibroma of the external auditory canal: report of an adult case

Myofibroma of the external auditory canal: report of an adult case. Objective: Myofibroma is a benign fibrous proliferative disease generally reported to occur in neonates and children. Similar lesions have been reported in adults, but solitary tumours affecting the external auditory canal are extremely rare. Only one such case has been reported in the literature. Case report: The case of solitary myofibroma occurring in the external auditory canal of a 42-year-old woman is presented. The diagnosis of myofibromatosis was made on the basis of its histological appearance and corroborated by immunohistochemical staining. Conclusions: Clinicians and pathologists must be aware that myofibromatosis may occur in adults at extremely rare locations.Myofibroma should be included in the differential diagnosis of fibrous lesions in the external auditory canal.
