Trichofolliculoma is a rare tumor that arises from immature hair follicular tissue. In this report, we present the case of a 51-year-old man with a trichofolliculoma in the left external auditory canal. Uniquely, there was no prior trauma in this patient, despite previous trauma being hypothesized in the etiology of this tumor. The lesion was excised using microsurgical instruments and the tumor was closely adherent to the cartilage of the external auditory canal. Histopathology following excisional biopsy confirmed the diagnosis.
