BACKGROUND: Melasma is an acquired, symmetrical hypermelanosis that occurs on sun-exposed areas of the skin. It has significant emotional and psychological effects on those affected with the condition. Melasma Quality of Life Scale (MELASQOL) is a specific questionnaire to identify the most impaired areas of melasma patient's life. OBJECTIVE: Our purpose of this study is to investigate the changing of MELASQOL after the treatment of melasma. METHODS: A total of 27 volunteers with melasma were enrolled in this 8-week treatment study. The patients were instructed to apply an arbutin-containing cream, once a day for 8 weeks. The assessment of outcomes included the colorimetric value (L*) and MELASQOL score. RESULTS: The arbutin-containing cream group increased more in the colorimetric values (L*) after the 8-week treatment (p<0.01). The MELASQOL score was decreased (p=0.02). No significant adverse reactions were observed. CONCLUSION: The treatment of melasma improves the QOL of melasma patients.

Lymphocytes can produce various kinds of cytokines which are responsible for the development of the infectious and allergic inflammation. We focused on the role of the lymphocyte in the pathogenesis of the nasal polyp. This study was designed to evaluate the functional differences of the lymphocytes between allergic and non-allergic polyp. Lymphocytes were obtained from peripheral blood and tissues of polyp in 12 patients with non-allergic polyp, 7 patients with allergic polyp and 5 normal subjects as control. Cytokines were measured with ELISA from each group of lymphocytes after stimulation with Concanavalin A (Con A). We compared the production of interleukin (IL)-2, IL-4, tumor necrosis factor (TNF)-alpha and interferon (IFN)-gamma between the non-allergic and allergic groups. The levels of IL-4 and IL-6 from polyp tissue lymphocytes were higher in allergic group, while those of IL-2 and IFN-gamma were higher in non-allergic group. The levels of IL-4, IL-6 and TNF-alpha from peripheral blood lymphocytes were higher in allergic group, and IFN-gamma was higher in non-allergic group. These results suggest that cytokine productivity of the polyp tissue lymphocytes appear to be parallel to that of the peripheral blood lymphocytes in each group and shows distinct pattern of ytokine production between two groups.

Elephantiasis nostras verrucosa is an uncommon disorder that is characterized by dermal fibrosis, hyperkeratotic verrucous and papillomatous lesions and this is all caused by chronic non-filarial lymphedema secondary to infections, surgeries, tumor obstructions, radiations, congestive heart failure and obesity. We report here on a case of elephantiasis nostras verrucosa that occurred on the left lower leg of a 54-year-old woman who had a past history of extensive skin grafts and recurrent infection.

BACKGROUND: Recurrent aphthous stomatitis (RAS) is usually the earliest sign of Behcet's disease. Hyperhomocysteinemia can damage endothelial cells and progress to obstructive vascular disease. It has been reported that hyperhomocysteinemia is a marker of activation in Behcet's disease. Enzyme 5,10-methylenetetrahydrofolate reductase may be one of the main factors that regulates plasma homocysteine levels. Homozygosity for the C677T (MTHFR C677T) mutation is associated with reduced activity of this enzyme and considered the most common genetic cause of elevated serum homocyteine levels. However its relationship to vascular injury in Behcet's disease remains controversial, and its relationship to RAS is unknown. Apolipoprotein E (Apo E) has both immunoregulatory and anti-infective features. Search for Apo E polymorphism and lipid composition in RAS patients might be a clue to pathogenesis of RAS. OBJECTIVE: To analyze the relationship of MTHFR gene C677T polymorphism, several epidemiologic factors such as age and sex, smoking, lipid composition and Apo E polymorphism to vasculitis in RAS, we assessed the MTHFR gene C677T polymorphism, Apo E polymorphism and lipid composition in RAS and normal population. METHODS: We analyzed data from the General Health survey conducted on 1,243 participants (M:F=281:962) over a 20 year-old in Incheon city. Medical interview and laboratory test for methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphism, apolipoprotein E polymorphism were completed. Statistical significance was analyzed by chi-square test and multistep logistic regression analysis. RESULTS: Among normal population over the age of twenty, a total of 34.2% (426/1,243) had RAS. Female predominance (4.5:1, p=0.003) was noted. The incidence of RAS in age group 20 to 39 year old is higher than the over 40 age group. The incidence is higher in smoking group compared to the nonsmoking group in multistepwise logistic regression analysis. Frequency of the MTHFR C677T genotypes was highest at CT compared to CC and TT homozygous genotype in normal and RAS patients group. There was no significant statistical differences in MTHFR genotypes in RAS patients compared to the control group. Similarly, Apo E genotype analysis revealed no significant statistical differences either. Apo E genotype and total cholesterol, HDL-cholesterol, triglyceride level didn't show any associations. CONCLUSION: This study revealed insignificant association between the MTHFR C677T mutation and RAS. Apo E genotype didn't show a significant statistical difference in RAS patients compared to normal controls.

A 37-year-old man presented with a 1-year history of asymptomatic ill-defined subcutaneous thickening with overlying whitish hairs on right occipital scalp. Histopathologic examination from this subcutaneous mass revealed neurofibromatous tissue with a diffuse infiltrative growth. S-100 protein staining showed decreased melanocytes and melanin in hair follicles. He was diagnosed as a diffuse neurofibroma associated with poliosis. To our knowledge, only two cases of poliosis associated with neurofibroma have ever been reported in English.

BACKGROUND: Pityriasis rosea is a common, acute self-limiting papulosquamous disorder in which many studies suggest viral causative factors in its pathogenesis. Recently, the link between pityriasis rosea and the reactivation of human herpes virus-6 (HHV-6) and HHV-7 infection has been suggested. This evidence suggests that targetting HHV-6 or HHV-7 may be an effective treatment for pityriasis rosea. OBJECTIVE: We treated pityriasis rosea patients with oral famciclovir to investigate the effect of oral famciclovir in pityriasis rosea. METHODS: A case group of seventeen patients with pityriasis rosea were treated with oral famciclovir (250 mg 3 times daily for 7 days). Clinical evaluation at 0, 1 & 2 weeks was undertaken. A skin biopsy and polymerase chain reaction analysis of HHV-6 from a skin specimen were performed. We analyzed 19 patients with pityriasis rosea who were treated with topical steroid and oral antihistamines retrospectively and considered them as the control group. RESULTS: On the 7th day after oral famciclovir treatment was started, pityriasis rosea had regressed completely in 3 patients (17.6%) and had regressed partially in 9 patients (52.9%). On the 14th day, 12 patients (70.6%) had achieved more than partial regression. On the 7th day, systemic symptoms had improved in all 9 patients. Clearance of skin lesions was achieved in average 7.57 days in patients who had regressed completely after 14 days' treatment. Histological examination of patients was compatible with pityriasis rosea and polymerase chain reaction analysis of HHV-6 was negative in all 8 patients. Compared with the control group, the treatment for patients in the case group seemed to have better effects, but statistical analysis failed to show any significant differences between the two groups. CONCLUSION: Famciclovir was not effective in the treatment of pityriasis rosea, but further investigation is needed.

Acrokeratosis paraneoplastica, or Bazex syndrome, is one of the paraneoplastic syndromes. The characteristic skin lesions include palmoplantar keratoderma, psoriasiform skin lesions, hyperpigmentation, and nail dystrophy. The most common associated neoplasms are squamous cell carcinoma of the upper respiratory tract and other kinds of tumors with cervical lymph node metastasis. A 63-year-old woman presented with an 11 month history of hyperkeratotic lesions on the palms and soles. Ten months before she had been diagnosed with adenocarcinoma of the colon and undergone a left hemicolectomy. We report a case of acrokeratosis paraneoplastica associated with colon cancer which persisted after removal of the primary cancer, but resolved with topical tretinoin treatment.
