Desmoplastic trichoepithelioma is a rare benign adnexal tumor that usually presents as an asym-ptomatic, firm, annular plaque. It most commonly occurs on sun-exposed areas in middle-aged women, especially on the face. Patients typically give a history of a single, slow-growing lesion that has been present for several years. The diagnosis of desmoplastic trichoepithelioma can be made when a triad of microscopic findings are observed in combination with a compatible clinical picture. We herein report a case of desmoplastic trichoepithelioma associated with syringomas on the face of a young woman. (Korean J Dermatol 2003;41(12):1650~1653)

Bichloroacetic acid(BCA), ond of the chloroacetic acids, is an effective tissue cauterant when used in high concentration. In dermatologic surgery, BCA, in the form of 100% solution, has been used to treat xanthelasma, sebaceous hyperplasia, verrucae, hard and soft com, seborrheic keratosis, ingrowing nail, cysts. The cauterization with BAC 100% solution can be used with a simpler technique than the sugical excision or electrical cauterization, without complicated appliance such as LASER generators, so the dermatologic surgical technique - BCA chemical cauterization, topical treatment - can be selected as a treatment of choice for many dermatologic conditions in outpatient offices. BCA destroys the barrier function of the epidermis and penetrates deeply through the papillary dermis and then creates the effect in the papillary dermis and reticular dermis. As a result, regeneration of new dermal collagens and a new epidermis occurs. This pharmacologic effect of BCA makes 100% solution of BCA to be used in the treatment of xanthelasma, pigmented nevi, ance scars with good clinical outcomes.

Tufted hair folliculitis is an inflammatory disorder of the scalp characterized by a peculiar tufting of hair within areas of scarring alopecia. Histopathological studies reveal perifollicular inflammation around the upper portions of the follicles sparing the hair root level. Within areas of inflammation, several follicles converge toward a common follicular duct with a widely dilated opening. The cause of tufted hair folliculitis is unknown, and the therapeutic approach is problematic. We present herein a patient with a 28-year history of recurrent and progressive tufted hair folliculitis. A 33-year-old man was referred to our department for the treatment of chronic and relapsing inflammatory lesions of the scalp. The clinical examination revealed a circumscribed area of 15cm length and 10cm width on the occipital area of the scalp which was characterized by hair tufting and exudates. Histopathologic findings were typical for tufted hair folliculitis. We believe that hair tufting is a secondary phenomenon which may occur in several inflammatory diseases of the scalp.
