A case of multiple trichilemmal cysts (TC) is presented. TC is known to be a kind of keratinous cyst with lining cells showing trichilemmal keratiniration. A 63-year-old female patient presented with a 30 year duration of increasing in size and number of twenty five nodular lesions on the scalp. All twenty five TC on the scalp were totally excised and examined microscopically. However, the evidence of proliferation or malignant change like the previous case reports was not found in our case.

BACKGROUND: Acne is a relatively common disorder, especially in the adolescent. The condition is characterizecl by comedones, papules and pusi:ules. Acne patients frequently wash their face. Cleansing with an effective agent is therapeutic and preventive for patients suffering from acne vulgaris. OBJECTIVE: The study was designed to compare thc efficacy and safety of a facial clemser consisting of 1% triclosan and 0.5% Ku Shen and a in in the treatment of facial acne vulgaris. METHODS: The study was camed out on two groups of people: a treatment and a control group. Efficacy and safety were assessed at baseline and at weeks 1, 2, 3, 4, 6, 8, 10 and 12. Efficacy was determined by investigating counts of non-inflamatory open and closed comedones, and inflamatory papules and pustules. Global improvement was also assessed. RESULTS: At week 12, the mean counts in the differe,nt lesions were as follows; 11.2 versus 17.2 for total lesions (p<0.05); 9.4 versus 11.3 for non-inflammatory lesions (p<0.05); 1.8 versus 5.9 for inflammatory lesions (p<0.05) in the treatment and control group, respectively. A Statistically significant difference was observed in patients overall self-assessment (p<0.05). The Group applying the facial cleanser with 1% triclosan and 0.5% Ku Shen felt significantly better than the one applying the control facial cleanser. Some patients developed mild and transient local side effects. CONCLUSION: Cleansing three times a day with a facial cleanser consisting of l% triclosan and 0.5% Ku Shen was found to be effective ancl safe for patients suffering from acne vulgaris.

A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

Tegafur [1-(tetrahydro-2-furyl)-5-fluorouracil], the prodrug of 5-fluorouracil, is an anticancer agent. Several cutaneous reactions have been reported following systemic 5-fluorouracil for the treatment of malignancies. We report a patient with marked inflammation of the actinic keratosis following the use of tegafur for stomach carcinoma. The side-effect with 5-fluorouracil was beneficial as most actinic keratosis cleared following the inflammatory reaction. Dermatologists and oncologists should be aware of this potential side-effect, not only because it may become more prevalent but, most importantly, because it is not an allergic reaction to 5-fluorouracil but a dose-dependent response, and the chemotherapy may be continued in most patients.

BACKGROUND: Although the histologic picture of epidermolytic hyperkeratosis is diagnostic for bullous congenital ichthyosiform erythrokerma (BCIE), it is not specific for it. It is found also in several other conditions, that is, linear epidermal nevus, epidermolytic keratisis palmaris et plantaris and epidermolytic acnthoma. Among these, BCIE is caused by mutations of the defferentiation s0pecific keratins K1 and K1-. These mutations produce a weakened cytoskeleton that is prone to collapse resulting I cell fragility and lysis. But the pathogenesis of epidermal nevus showing the similar histologic feature with BCIE is not known. OBJECTIVE: The purpose of our study is to conpare the electron microscopic picture and the immunohistochemical features, and to find the possible pathogenesis of both diseases. METHODS: We evaluated the clinical, histopathologic nd electron microscopic features of 5 BCIE cases and 14 epidermal nevus cases which were histologically diagnosed with epidermolytic hyperkeratosis at the department of dermatology at Wonju Christian Hospital, Shinchon Severance Hospital and Yongdong Severance Hospital, from January 1981 to June 1994. The immunohistochemical staining(PAP method) using monoclonal antibody against cytokeratin was performed on BCIE and epidermal nevus. RESULTS: Light microscopy of both BCIE and epidermal nevus showed the same histologic changes including hyperkeratosis, increased keratohyaline granules, acanthosis and perinuclear vacuolization of upper malpighia layer. Electron mioroscopic findings in both diseases were similar. Aggregation of tonofilaments is noted in the squamous cells, but is not evident in basal cells.In immunohistochemical study of both diseases, 34betaE12 is stained in the whole epidermis and is stuonger ex0ressed in the basal layer tan suprabasal layers. LP34 staining is evident in suprabasal cell layers up to the cornified cell layer. CONCLUSION: Electron microscopy and immunohistochemical study of both diseases showed the same finding. We thind that a defect in the differentiation specific keratins, K1 and K10 is perhaps involved in epidermal nevus histologically showing epidermolytic hyperkeratosis as in BCIE.

Supernunmerary nipple is a developmental anomaly occuring alon, the course of the embryological milk lines. This entity has receieved little attention in the dermatologic literature and has been confused with a pigmented nevus in some cases. We have experienced two ease of the more unusual form of supern umerary nipple. According to the Kajavas classification, our caes are classified as polithelia pilosa and complete breast with nipple.

BACKGROUND: Bentonite clay, which is a major component of mud pack, has been used for various purposes in cosmetics. Glycolic acid is known to be effective in the treatment of acne. Al-though those products are used widely, information on the mode of action and effects on the skin are little and controversial till now. OBJECTIVE: To investigate whether bentonite alone, or bentonite with glycolic acid in mixed formulation affect the stratum corneum leading to alteration on cutaneous barrier function and whether those products alter the lipid lamellae and desmosomes of corneocytes. MATERIALS AND METHODS: Mud pack-type ointment of bentonite, bentonite and 5% glycolic acid formulation, bentonite and 10% glycolic acid formulation were applied on the volar fore-arm of the five healthy men and flank skin of five 6-8 week old hairless mice. Transepidermal water loss and capacitance were measured. Electron microscopic examination after ruthenium tetroxide postfixation was performed on the flank skin of the mice. RESULTS: Transepidermal water loss(TEWL) increased immediately and normalized 4 to 6 hours later after removal of vapor permeable membrane in both mouse and human. Capacitance did not show any evidence of change in the water content of the stratum corneum. Electron microscopic examination revealed that lipid lamellae and desmosome of corneocytes were not de-graded, but lamellar body secretion and partially electron-lucent material was-increased in 10% glycolic acid and bentonite mixture-treated area. CONCLUSION: Barrier function of stratum corneum is not disturbed by bentonite and glycolic acid formulations at the concentration used. Barrier structures are not disrupted, but lamellar body secretion and partially electron-lucent material was increased by bentonite and glycolic acid formulations at higher concentration.

BACKGROUND: Allergic reactions are known to be associated with symptomatic aggravation of atopic dermatitis. Skin prick tests were used as a routine in vivo screening test for the evaluation of allergic patients. Many tests to detect specific IgE antibody including RAST, FAST and MAST chemilu-minescent assay (MAST-C~LA) were also used. Previous studies revealed that the results of skin prick tests and MAST-CLA were well correlated in patients with asthma, allergic rhinitis and urticaria. OBJECTIVES: The purpose of this study was to evaluate the effectiveness of MAST-CLA compared with skin prick tests in patients with atopic dermatitis. METHODS: We performed the chemiluminescent assay with 35 allergens and skin prick tests with 23 allergens common with allergens used in MAST-CLA in 34 patients with atopic dermatitis. The positive reaction rate of allergens in each test and sensitivity, specificity, efficiency, positive predictive value and negative predictive value of MAST-CLA to the skin prick test were evaluated and MAST net volts of serum total IgE was compared with PRIST.
