Low-grade malignant eccrine spiradenoma (spiradenocarcinoma) is a rare sweat gland tumor, which usually arises from a pre-existing benign eccrine spiradenoma. This paper presents the case of a 55-year-old male who had a lesion in his right elbow for 10 years. The microscopic examination revealed a well-demarcated, multilobulated tumor in the dermis and subcutis, which presented with many blood-filled vessels and extensive hemorrhage. The tumor was composed of hyperchromatic, round to oval cells with nucleolar prominence, mild to moderate atypia, and increased mitotic index...

Syringocystadenoma papilliferum (SCAP) and apocrine hidrocystoma (AH) are benign apocrine neoplasms that usually occur separately. SCAP arises predominantly in head and neck, while AH typically develop in periorbital area. We report a case of a 68-year-old male with an asymptomatic erythematous papulonodule that occurred on his back 3 years ago. Histologic examination showed cystic invagination extending from the epidermis into the dermis with some papillary projections. The invaginated portion was lined by epithelial bilayer composed of cuboidal and columnar cells, and decapitation secretion was observed in the inner epithelial layer...

Anti-p200 pemphigoid is an uncommon subepidermal autoimmune bullous disease that, unlike many other autoimmune bullous diseases, has not previously been associated with hematological diseases. The diagnosis of anti-p200 pemphigoid in a patient with congruent clinical features requires the demonstration of subepidermal blistering, with linear deposition of immunoglobulin (Ig) G and/or C3 at the dermoepidermal junction on direct immunofluorescence, and a floor-binding pattern on indirect immunofluorescence. In addition, the detection of antibodies against p200 antigen via immunoblotting is ideal but not readily accessible in many facilities, leading to a potential under-recognition and under-diagnosis of this condition...

Becker's nevus (BN) is a benign hamartoma that may present as a distressing cosmetic problem. The treatment of BN poses a significant challenge as current therapeutic modalities are suboptimal and have an increased risk of adverse effects, such as scarring and dyspigmentation. We present the use of non-ablative fractional laser therapy combined with Q-switched Nd:YAG laser as a possible therapeutic option for BN treatment and review relevant literature to discuss its efficacy and limitations.

BACKGROUND: We found microRNA (miR)-1246 to be significantly differentially expressed between severe active alopecia areata (AA) patients and healthy individuals. OBJECTIVE: To explore the role and mechanism of miR-1246 in severe AA. METHODS: Expression of miR-1246, dual-specific tyrosine phosphorylation-regulated kinase 1A (DYRK1A), and nuclear factor of activated T cells 1c (NFATc1) in peripheral CD4+ T cells and in scalp tissues of patients were detected using RT-qPCR, Western blot, and immunohistochemistry assays...

BACKGROUND: Atopic dermatitis (AD) patients usually wonder if their condition will worsen after vaccination or if they should continue with the treatment they are receiving. Considering that many patients treated with dupilumab had previously experienced severe AD symptoms and flares, the concerns are more understandable. OBJECTIVE: This study aimed to investigate the safety of the coronavirus disease 2019 (COVID-19) vaccination in patients with AD treated with dupilumab...

BACKGROUND: The prevalence of psoriasis differs by population, and it appears to be more common among Europeans than in East Asians. Recent genome-wide association studies (GWAS) have identified alleles that increase the risk of psoriasis, and these alleles may present different frequencies in different geographic regions. OBJECTIVE: We aimed to gain insights into the causes of differences in disease frequencies according to populations and the factors affecting prevalence and pattern differences...

BACKGROUND: The advent of fractionated picosecond (ps) lasers has provided an opportunity to explore new ways of creating microinjuries in the skin to induce skin rejuvenation. OBJECTIVE: To compare the efficacy and safety of diffractive optical element (DOE)-assisted ps neodymium: yttrium-aluminum-garnet (Nd:YAG) lasers with 532-nm and 1,064-nm wavelengths (532-nm and 1,064-nm Nd:YAG P-DOE) using a novel fractional handpiece for the treatment of photoaged skin...

BACKGROUND: The gestational risk factors predispose to the manifestation of early childhood atopic dermatitis (AD). OBJECTIVE: We evaluated the association between modifiable and non-modifiable gestational and prenatal risk factors that affect the AD prevalence in children. METHODS: We performed the systematic review and meta-analysis of cohort studies (n=27) in PubMed and EMBASE (2000~2021). A meta-analysis was performed using random-effects models to estimate pooled odds ratios (OR) or hazard ratio (HR)...

BACKGROUND: Psoriasis localized to certain body areas, such as the scalp, nails, palms, soles, intertriginous regions, and genital regions, is reportedly difficult to treat. OBJECTIVE: To investigate the biologics-resistant areas in South Korean patients with psoriasis treated with biologics. METHODS: The study included 50 patients with chronic moderate to severe plaque psoriasis from the Pusan National University Hospital and Chosun University Hospital between October 2019 and September 2020...
