“…9 Two years after, O'Mahony reported the second case of EAC trichofolliculoma presenting as a fleshy mass occluding the left external auditory meatus and leading to hearing loss and tinnitus. 10 Our case also had conductive hearing loss on the left ear, but she did not have any complaint of tinnitus. In 1986, Cohen and Davis reported a young girl who developed multiple trichogenic adnexal tumours as well as two polypoid ear lesions caused by trichofolliculoma.…”

“…Trichofolliculoma is a pilosebaceous follicle hamartoma in which several hairs are formed within a single pilosebaceous unit and protrude out of a single orifice. It is mostly observed over the head and neck area, particularly the face in young adults, but has also been reported over the vulva, scrotum, penis, external auditory meatus, intranasal area, lips, and upper extremities [1][2][3][4][5][6][7]. It is usually seen in adults but a single case of congenital trichofolliculoma has also been reported [8].…”

Trichofolliculoma is a pilosebaceous follicle hamartoma in which several hairs are formed within single pilosebaceous unit and protrude out of single orifice. Herein we report a 45-year-old woman with a trichofolliculoma of the eyebrow. Case synopsisA 45-year-old woman presented with an asymptomatic slowly growing swelling over the right eyebrow of 6 months duration. There was no history of similar lesion elsewhere in the past and no similar skin lesion in any family members. The patient could not recall any history of trauma at the site of swelling.Examination revealed a solitary skin colored shiny, firm, non tender nodule of size 0.9X 0.5X 0.5 cm over the infero-medial aspect of the right eyebrow. The nodule had an umbilication in the center with a keratinous plug and a few terminal hairs emerging from it (Figure 1). No other mucocutaneous abnormality was detected and systemic examination was unremarkable. The nodule was excised and sent for histopathological examination. Figure 1. Solitary skin colored shiny, firm, umbilicated nodule with keratinous plug and few terminal hairs emerging over infero-medial aspect of eyebrow.

“…Trichofolliculomas (TFs) are rare adnexal tumors, reported as hamartomatous tumors or as benign follicular neoplasms, commonly affecting the head and neck regions. However, auricular involvement is extremely rare, and to the author's best knowledge, only 2 cases of ear or ear canal TF has been described in the English literature [1,2]. These benign hair follicle-derived tumors may clinically mimic malignancy such as basal cell carcinoma of the auricle.…”

Trichofolliculoma (TF) is a follicular hamartoma in which hairs protruding out of single orifice. To the best of my knowledge, only two auricular TF has been reported in the English literature. Moreover, clinically TF have been described to mimic malignancy. I present a case of an adult female with mass at the intertragal notch of the left auricle for several years. The clinical diagnosis was thought to be epidermoid cyst, accessory tragus, and other benign skin adnexal tumor. To prevent recurrence, the wide local excision of the mass was performed. The final diagnosis of TF was made. No recurrence was noted during the follow-up of 1 year. It is important for otologists to be familiar with the clinical and pathologic characterization of TF, to make the correct diagnosis.
