Objective: The purpose of this study is to evaluate the effectiveness and safety of an anion textile in patients suffering from AD.
Acute localized exanthematous pustulosis (ALEP) is a localized variant of acute generalized exanthematous pustulosis, which is characterized by the eruption of multiple scattered pustules following drug administration. A 26-year-old woman presented with multiple erythematous pustules on her face, which had appeared three days after taking antibiotics. Histopathological findings showed subcorneal pustules and mixed inflammatory cell infiltration in the dermis.

Here, we report a case of a 50-year-old man with multiple cystic nodules and alopecic patches on his scalp. On histopathological examination, the folded cyst was found to be lined by stratified squamous epithelium, while flattened sebaceous gland cells were identified in the cystic wall.

Although many adverse effects of MTX, including cutaneous ulcerations, have been documented, multifocal mucosal ulceration mimicking Behçet's disease has not been reported. In our case, a 63-year-old female presented with oral, vaginal ulcer and multiple purpuric patches on both legs.

Recently, mutations in the human hairless (HR) gene have been implicated in its pathogenesis. The identification of mutations in the HR gene is important for differentiating between APL and alopecia universalis (AU).

We evaluated changes in the hair follicles associated with Se imbalance in a C57BL/6 mouse model to better understand the role of Se in hair growth. Fifteen C57BL/6 mice were assigned to diets providing excessive, adequate, or deficient amounts of Se.

The clinical features of vitiligo are similar to those of ND, but the two diseases have different treatment responses and prognoses. We report here on a rare case of vitiligo that was coexistent with ND.

Although syringoma is a common benign neoplasm, there have been no effective therapies for its removal. Conventional therapies for syringomas, including surgical excision, electrodessication, chemical peeling, topical atropine or tretinoin, cryosurgery, and laser therapy, can lead to cosmetic defects such as hyperpigmentation or scarring due to epidermal damage.

AOS can also be associated with extensive lethal anomalies of internal organs, including the central nervous, cardiopulmonary, gastrourointestinal, and genitourinary systems. Generally, the more severe these interrelated anomalies are, the poorer the prognosis becomes.

Objective: To evaluate the efficacy and safety of EO for treating reactive vascular lesions.
Materials And Methods: Patients with reactive vascular lesions, such as pyogenic granulomas or venous lakes, were enrolled.
Ashy dermatosis, also known as erythema dyschromicum perstans, is a peculiar, slowly progressive, idiopathic dermal melanosis. In most cases, slate gray- to lead-colored patches are symmetrically distributed over the body. Ashy dermatosis with a unilateral distribution is rare.

Although numerous cases of progressive macular hypomelanosis have been reported, there have been no clinicopathologic studies of progressive macular hypomelanosis in Korean patients.
Objective: In this study we examined the clinical characteristics, histologic findings, and treatment methods for progressive macular hypomelanosis in a Korean population.
This study was to determine which immunologic factors contribute to the prognosis of patients with alopecia areata (AA) who were receiving oral cyclosporine A and methylprednisolone. Patients with > 25% hair regrowth were defined as responders, and patients exhibiting < or = 25% regrowth were poor-responders. The serum levels of IL-18 and soluble IL-2 receptor (sIL-2R) were measured at baseline in 21 patients with AA and 22 control subjects.
