Trichofolliculoma in External Auditory Canal / 대한이비인후과학회지

ABSTRACT

Trichofolliculoma is an uncommon follicular hamartoma of hair follicle tissue, typically occurring on the face and skin of the head and neck and appearing as papules or nodules. Dents in the central portion and immature white hair may be observed. Asymptomatically, trichofolliculoma occurs at any age but rather frequently in adults in many cases. A 47-year-old man presented a right ear canal mass, which had not been treated for 12 years. The tumor began to increase its size 4 years ago. A little red bump blocked the entrance of the right external auditory canal and there was a little dinge at the center of bump with growing black hair. This case was first reported in our country. Thus, we report this rare case with a review of the literature.
