Tricofoliculoma del conducto auditivo externo. Un caso excepcional de presentación agresiva

Abstract

Introduction and objective: Trichofolliculoma is a rare and benign adnexal tumour of the hair follicles. The location of this tumour in the external auditory canal (EAC) is exceptional. Its diagnosis is histopathological. Objective: Present an exceptional clinical case, the finding of a trichofolliculoma in the external auditory canal. Clinical case: We present the clinical case of a CAE trichofolliculoma that, when associated with a cholesteatoma, had an aggressive manifestation with destruction of the temporal bone. Conclusion: Trichofolliculoma is a rare tumour of the hair follicles whose location in the EAC is exceptional. The aggressive behaviour of the case presented was due to its association with a cholesteatoma, probably secondary to the obstruction and recurrent inflammatory processes of the tumour.
