Trichoepithelioma is a benign tumor originating from hair follicles. Histopathological examination is crucial in the diagnosis as it can be confused with basal cell carcinoma clinically. A 23-year-old female patient presented to our clinic with complaints of a mass at the entrance of the left external auditory canal, decreased hearing, and occasional ear bleeding for five years, starting after pregnancy. Physical examination revealed a purple-gray mass completely covering the left external auditory meatus. The histopathological examination of the mass, which was surgically excised, was reported as trichoepithelioma. In this article, clinical findings, diagnosis, and surgical treatment process of a case of trichoepithelioma, which is rarely observed in the external auditory canal, were presented in light of current literature.

“…Trichoepithelioma is a benign trichogenic tumor that may differentiate into follicular pattern. [ 1 2 ] There are two clinical types of trichoepitheliomas: (1) Solitary non-familial type and (2) multiple familial type. The familial type is an autosomal dominant inherited syndrome known as multiple familial trichoepitheliomas or Brook–Fordyce disease.…”

Trichoblastoma is a rare, slow-growing, benign cutaneous tumor derived from follicular germinative cells. Trichoblastoma commonly appears as an asymptomatic, symmetrical, well-circumscribed, skin-colored to brown or blue-black papule or nodule. It may appear clinically and histologically similar to basal cell carcinoma, making its diagnosis challenging. Even on dermoscopy, it is challenging to differentiate trichoblastoma from basal cell carcinoma. In practice, it is important to differentiate the two, because the choice of treatment and resulting prognosis differ between the lesions. Surgical biopsy to analyze histopathological and immunohistochemical differences is the gold standard for diagnosing and differentiating trichoblastoma from basal cell carcinoma. Trichoblastoma typically has a favorable prognosis, with a low incidence of recurrence, progression or association with malignancy. This paper provides a review of the epidemiology, clinical presentation, dermoscopy, histology, immunochemistry, treatment, and prognosis of trichoblastoma.
