A Rare Case of Localized Hypertrichosis in Conjunction with Erythema Nodosum.

Acquired hypertrichosis can occur in local inflammation. Erythema nodosum (EN) is a hypersensitivity reaction to various underlying antigenic stimuli including , which causes inflammation in the septa of subcutaneous fat. There were several case reports that describe the association of localized hypertrichosis (LH) with traumatic panniculitis and lupus panniculitis.

Pigmented contact dermatitis and hair dyes: A retrospective case-control multicentre study in Korea.

Background: Pigmented contact dermatitis (PCD), a rare variant of non-eczematous contact dermatitis, is clinically characterized by sudden-onset brown or grey pigmentation on the face and neck. It is hypothesized to be caused by repeated contact with low levels of allergens.

Objectives: This study evaluated the risk of using hair dyes in patients with PCD in Korea.

The Low-Fluence Q-Switched Nd:YAG Laser Treatment for Melasma: A Systematic Review.

Melasma is a common pigmentary disorder with a complex pathogenesis, of which the treatment is challenging. Conventional treatment often leads to inconsistent results with unexpected pigmentary side effects and high recurrence rates. Recently, the low-fluence Q-switched Nd:YAG laser (LFQSNY) has been widely used for treating melasma, especially in Asia.

Use of hydroxychloroquine in dermatology: A multicenter retrospective study in Korea.

Despite the expanding clinical application of hydroxychloroquine in dermatology, the overall data on hydroxychloroquine use among dermatologists are limited. With retrospective review of the medical records of the 790 patients who were prescribed hydroxychloroquine, we classified the diagnoses into 12 disease categories, the lupus erythematosus group being the largest. The lupus erythematosus group had the longest prescription duration (median, 6.

Erythema induratum of Bazin in a 10-year-old boy.

Erythema induratum of Bazin (EIB) is a form of tuberculid resulting from hypersensitivity to tuberculosis antigen. EIB occurs most commonly in middle-aged women and is not typically seen in children. Here, we present a rare case of EIB, presenting as a chronic nodular panniculitis, in a 10-year-old Korean boy.

Anesthetic cream relieves pain after cryotherapy treatment of plantar and palmar warts.

Cryotherapy using liquid nitrogen is an effective and commonly used treatment for palmoplantar warts. However, pain can be a limiting factor in the effective use of cryotherapy. In this study, we found that a single application of anesthetic cream following cryotherapy treatment of warts reduced posttreatment pain and led to improved tolerability of the procedure.

Alopecia areata and overt thyroid diseases: A nationwide population-based study.

An association between alopecia areata (AA) and other autoimmune diseases has been reported. We investigated the associations between AA and overt autoimmune thyroid diseases. A nationwide, population-based, cross-sectional study was performed using the Korea National Health Insurance claims database.

Vitiligo and overt thyroid diseases: A nationwide population-based study in Korea.

Background: Associations between vitiligo and thyroid diseases have been reported repeatedly.

Objective: We investigated the associations between vitiligo and overt autoimmune thyroid diseases and thyroid cancer using the Korean National Health Insurance claims database.

Methods: We defined patients with vitiligo as those whose records showed ≥4 physician contacts between 2009 and 2013 in which vitiligo was the principal diagnosis.

Correlation between Severity of Atopic Dermatitis and Sleep Quality in Children and Adults.

Background: The atopic dermatitis (AD) can limit a patient's physical and psychosocial development as well as lower their overall quality of life (QOL), including sleep quality.

Objective: The purpose of this study was to evaluate the relationships between clinical disease severity, QOL and sleep quality in children and adults with AD.

Methods: The SCORing atopic dermatitis (SCORAD) was examined to evaluate the severity of AD in fifty adult AD patients and 50 children AD patients.

Subungual Posttraumatic Ectopic Nail.

Ectopic nail is defined as the malformation of nail tissue in a location other than the usual nail unit. We present a 12-year-old boy with a single dystrophic thumb nail after an injury. The nail was observed under the original nail and it is linked to the original nail plate by longitudinal bridge formation with parallel growth.

A Rare Case of Atypical Myxoid Cellular Neurothekeoma in a 6-Year-Old Girl.

Neurothekeoma (nerve sheath myxoma)is a benign tumor of probable nerve sheath origin. The atypical cellular variant of this tumor, showing a peculiar histologic pattern, has been very rarely reported in the literature. The atypical variant of cellular neurothekeoma is characterized by features such as large size, deep penetration extending into skeletal muscle and/or subcutaneous fat, diffuse infiltration borders, vascular invasion, high mitotic rate and marked cytologic pleomorphism.
