A nationwide study of acne treatment patterns in Korea: analysis of patient preconceived notions and dermatologist suggestion for treatment.

Patients often have preconceived notions about acne treatments before visiting dermatologists. The aim of this study was to explore the association between patients' beliefs regarding acne and physicians' suggestion for treatment modality in dermatology clinics. A cross-sectional, nationwide multicentre study was conducted.

A case of celecoxib induced acute generalized exanthematous pustulosis.

Acute generalized exanthematous pustulosis (AGEP) is manifested by rapid development of many sterile, nonfollicular pustules on a background of edematous erythema. More than 90 percent of AGEP are induced by medication, mostly antibiotics. Drug patch test can be helpful in the diagnosis of AGEP.

Dermatomyositis associated with generalized subcutaneous edema and Evans syndrome.

Although periorbital edema is a common manifestation of dermatomyositis (DM), generalized subcutaneous edema associated with DM is extremely rare. Evans syndrome is an autoimmune disease in which an individual's antibodies attack one's own red blood cells and platelets. Evans syndrome is rarely a presenting feature of DM.

Subcutaneous dermatofibroma.

Dermatofibroma (DF) is usually confined to the dermis and the overlying epidermis is usually hyperplastic. Although DF with deep subcutaneous extension is commonly encountered, purely subcutaneous DF is uncommon. In this review, we describe a case of a 41-year-old male patient who presented with a painless, subcutaneous, hard papule on the left thigh.

Linear Lichen Sclerosus along the Blaschko's Line of the Face.

Lichen sclerosus et atrophicus (LSA) is an inflammatory disease that primarily causes anogenital lesion in middle aged women. We present here a case of facial LSA with an asymptomatic, well-demarcated, whitish to bluish, atrophic patch in a linear pattern on the forehead of a 48-year-old woman. This case showed an atypical clinical presentation and it mimicked en coup de sabre, but the histopathologic results confirmed the diagnosis of LSA.

Acute generalized exanthematous pustulosis caused by diltiazem.

Acute generalized exanthematous pustulosis is clinically characterized by fever, pruritus and an acute pustular eruption. It can be described as having an abrupt onset and then spontaneous resolution occurs shortly after the start of symptoms, and there is usually only a single episode. Most cases have been triggered by the ingestion of drugs.

A multicenter epidemiological study of acne vulgaris in Korea.

Background: Acne is a common skin disorder that affects both adolescents and adults. However, few epidemiological studies on this condition have been conducted in Asia.

Objectives: The purpose of this study was to analyze the incidence of acne and to identify its demographic and clinical features and aggravating factors.

A case of morpheaform sarcoidosis.

Sarcoidosis is an idiopathic multisystem disease with various cutaneous presentations, and it is characterized by the presence of non-caseating granulomas in the affected organs. The specific manifestations are papules, plaques, nodules, ulcers and scar. We report here on a variant of sarcoidosis on a 71-year-old woman who showed an indurated plaque on the forearm.

A case of hydroa vacciniforme.

Hydroa vacciniforme (HV) is a rare and chronic pediatric disorder that is characterized by photosensitivity and recurrent vesicles that heal with vacciniforme scarring. The pathogenesis of HV is unknown; no chromosome abnormality has been identified. HV patients have no abnormal laboratory results, so the diagnosis of HV is based on identifying the associated histological findings in a biopsy specimen and using repetitive ultraviolet phototesting to reproduce the characteristic vesicles on a patient's skin.

Treatment-seeking behaviors and related epidemiological features in Korean acne patients.

Little is known about the treatment-seeking behaviors of acne patients, especially Asian acne patients. This study was performed to obtain detailed information about the treatment-seeking behaviors in Korean acne patients. Patients who visited the dermatology departments at 17 university hospitals completed a self-administered questionnaire.

The treatment of syringomas by CO(2) laser using a multiple-drilling method.

Background: Syringomas are relatively common benign adnexal tumors, predominantly developing in middle-aged women. They frequently involve the periorbital areas and cause cosmetic problems. Up to now, various treatment modalities such as electrodesiccation, laser ablation, cryosurgery, and some chemical peelings have been tried.

Case of childhood granulomatous periorificial dermatitis in a Korean boy treated by oral erythromycin.

Childhood granulomatous periorificial dermatitis (CGPD) is a disease presenting most commonly in prepubertal children as yellow-brown papules limited to the perioral, perinasal and periocular regions. The condition is benign, self-limiting and is not associated with systemic involvement. We herein report a case of an 11-year-old Korean boy with multiple, asymptomatic, monomorphic, red-to-yellow-colored papular eruptions on the perioral areas of 7-month duration.

A new dermal equivalent: the use of dermal fibroblast culture alone without exogenous materials.

Background: During the past decade, several kinds of skin equivalents have been developed. However, the dermal equivalents have all contained exogenous materials, which can be difficult to obtain and a source of infections.

Objectives: The aim of this study was to develop a new dermal equivalent by culturing dermal fibroblasts alone without exogenous materials and to evaluate its applicability in vitro and in vivo.
