Trichofolliculoma in Korean Patients: A report of six cases

ABSTRACT

Trichogenic tumors are a very rare group of primary cutaneous neoplasms and a few tumors have been recognized. Trichofolliculoma is a benign, papular, organoid adnexal tumor of the skin and presents as a solitary skin-colored nodule. We report six cases of trichofolliculoma occurred in Korean patients consisting of three male and three female patients. The duration of disease was variable from 3 months to 5 years. The site of tumor was limited to the face and included eyelid in two cases, nose in two cases, cheek and posterior aspect of ear in each one case. The size of the mass varied from 4 to 8 mm in diameter. Microscopically, all the cases showed large central cystic hair follicle with numerous secondary follicular buds, producing a radiating pattern. The stroma was fibrotic and well demarcated from the adjacent dermis.
