Abstract:
Trichofolliculoma is a benign tumor of hair follicle and is intermediate in differentiation between a hair nevus and a trichoepithelioma. It is a rare dermatosis first described by Fessler in 1924. Clinically, asymptomatic 4-5 mm sized solitary tumor usually occurs on the scalp, head and neck in the adultnood, This tumor may be clinically suspected if occurs as a small domeshaped nodule with a central umbilication showing small wisps fimmature hairs. Microscopically, the turnor shows one or several keratinfilled cysts in the dermis which are surrounded by spuamous epithelium, and contain horny meterial and birefringent fragments af hair shaft. These are primary hair follicles. And there are small secondary hair follicles which appear to radiation from the pimary hair follicles and have fine hair. The surrounding squarnous epithelium of primary follicles form epithelial strands, and interconnection the secondary hair follicles. We presented here a case of trichofolliculoma with typical clinical and histopthological findings in a 41 year-old male patient.
