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.

Pruritic folliculitis of pregnancy of pregnancy is a specific dermatoses of pregnancy which is characterized by erythematous follicular papules and pustules between the fourth and ninth month of pregnancy. It has usually resolved by 4 weeks of postpartum and has no adverse implications for mother and baby. We report a case of pruritic folliculitis of pregnancy in a 24-year-old primigravida woman who had had monomorphic erythematous follicular papules and pustules on her anterior chest wall and back. Histopathological findings of erythematous papules showed acute folliculitis and perifolliculitis. The skin lesions improved rapidly with 2 weeks of delivery without treatment.

BACKGROUND: Xerosis is a relatively common disorder, especially in the elderly. The condition is characterized by fine scaling and is associated with generalized pruritus. OBJECTIVE: The purpose of this study was to evaluate the clinical efficacy, safety and tolerability of Zalsming cream in patients with xerosis and pruritus. METHODS: Thirty patients were treated with Zalsming cream. Clinical efficacy, as measured by the score of subjective symptom and objective signs, transepidermal water loss(TEWL) and electron microscopic finding, were asessed at 2, 4, and 6 weeks after topical application of the cream. RESULTS: The scores of clinical signs and TEWL showed statistically significant improvements. No one developed any local or systemic side effects. CONCLUSION: Topical application of Zalsming cream was found to be effective and safe for patients suffering from xerosis and pruritus.

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.

BACKGROUND: Topical irritants disrupt the cutaneous permeability barrier through the removal of stratum comeum lipids. This perturbation of barrier integrity stimulates a variety of homeostatic repair responses that ultimately result in the normalization of bamer function. Object To measure the effect of desoxymethasone ointment, vaseline and hydrobase on the barrier recovery of benzalkonium chloride (BKC) imtated skin. MATERIALS AND METHODS: The left flank skin of 2-3 monthold hairless mice was treated with BKC and then desoxymethasone ointment, vaseline and hydrobase were applied. Transepidermal water loss (TEWL) was checked after 0, 3, 6, 9, 12, 15, 18, 21 and 24 hours. Electron microscopic examination was performed after 3 and 24 hours after desoxymethasone, vaseline and hydrobase had been applied. RESULTS: The recovery of TEWL was most prominantly observed in the desoxymethasone ointment treated group followed by vaseline and hydrobase. Electron microscopic examination using ruthenium tetroxide fixation revealed that secretion and numbers of lamellar bodies and complete formatice of lipid bilayers were most prominent at desoxymethasone ointment and vaseline treated group. CONCLUSION: Desoxymethasone ointment, vaseline and hydrobase can be good agents in improving bamer recovery after exposure to irritant material.

We report a interesting case of acral lentigenous malignant melanoma associated with pseudocarcinomatous hyperplasia in a 65-year-old women A skin lesion showed a 5 x 5cm sized, black colored protruding mass with ulcerative surface on the right great toe for the last 10 years. Histopathological findings reveled hyperplasia of epidermis and the epithelium of the upper protion of the adnexa admixed with a proliferation of atypical epitheloid melanocytes that involved the mid and lower portion of the epidermis and the papillary dermis. There were dyskeratotic cells and pseudohorn cysts between the aggregates of atypical melanocytes. Immunhistochemical staining revealed that the nucleus and cytoplasm of the atypical epitheloid cells were strongly positive for S-100 protein and negative for keratin. Keratin staining revealed aggregates of positively stained kertinocytes with dyskeratosis and pseudohorn cysts admixed and trapped among negatively stained atypical melnocytes. A unusual case of malignant melanorna associated with pseudocarcinomatous hyperplasia in which conventional hematoxylin and eosin stained sections were difficult to differentiation between malignat melanoma and squamous cell carcinoma. Immunohistochemical staining for S-100 protein and keratin were essential in establesging the correct diagnosis.

8.A Statistical Study of Dermatoses in Kangwon Province, 2010~2014.
Korean Journal of Dermatology 2016;54(1):26-33
BACKGROUND: The prevalence of skin diseases at a university hospital may not truly indicate their prevalence in the general population; nevertheless, it is the only available source of information. OBJECTIVE: This study aimed to investigate the prevalence of common dermatoses and compare this with previous reports. METHODS: We reviewed 29,477 new outpatients who visited the department of dermatology at Wonju Severance Christian Hospital from 2010 to 2014, and statistically analyzed the findings. RESULTS: Among the 29,477 outpatients, 14,501 (49.2%) were men and 14,976 (50.8%) were women. More patients were in their sixth decade (17.1%) or over 70 years (15.4%), in their seventh decade (13.5%) or in their fifth decade (13.0%), comprising 59% of the total outpatients. The 20 most common dermatoses were found to be urticaria, dermatophytosis, allergic contact dermatitis, other types of eczema, atopic dermatitis, pruritus, verruca, herpes zoster, alopecia, psoriasis, seborrheic dermatitis, drug eruptions, folliculitis, rosacea, benign epidermal tumor, melanocyte nevus, vitiligo, scabies, herpes simplex virus infection, and bacterial infection. In the distribution of dermatoses as disease groups, viral disease (11.2%), atopic dermatitis and eczema (10.7%); contact dermatitis and drug eruption (10.3%); erythema and urticaria (8.4%); fungal disease (7.6%); skin appendage disease (6.9%); seborrheic dermatitis, psoriasis, and pustular dermatoses (5.5%); epidermal nevi, neoplasms, and cysts (4.8%); pruritus and neurocutaneous dermatoses (4.6%); and acne (3.8%) constituted 73.8% of the total. CONCLUSION: Compared to the previous studies in the same area, the distribution of skin diseases was similar. The increasing tendency of older individuals with diseases in Gangwon province has persisted since 2000.

A 55-year-old Korean female patient who presented with longitudinal black pigmentation affecting the right thumbnail is described. Direct microscopic examination of nail tissue in 15% potassium hydroxide and cultures on Sabourauds glucose agar revealed Candida species. Cardida species as a cause of longitudinal melanonychia has, to our knowledge, been described only once in the literature. Our case may be the second one.
