Prognostic markers are needed for tumor-stage mycosis fungoides (MF) because of their variable prognosis. The objectives of this study were to explore prognostic markers for tumor-stage MF and assess the prognostic significance of clinically assessed MF tumor burden index (MTBI). MTBI was devised to consider the tumor size ≥ 2 cm, number ≥ 5, ulcers, and body surface area ≥ 50%.

We compared the risk of MACEs and all-cause mortality among patients with psoriatic disease treated with tumor necrosis factor (TNF)-α and interleukin (IL)-12/23 inhibitors in Korea.
Methods: Patients with psoriatic disease prescribed with TNF-α and IL-12/23 inhibitors since 2016 were selected from the Korean National Health Insurance Service (NHIS) Database.
Background: More than half of acne patients have truncal acne on their chest, back, and shoulders. However, since most studies on acne have focused on the face, data on clinical characteristics and proper management for truncal acne are insufficient.
Objective: To establish a Korean Acne Rosacea Society (KARS) consensus for experts' perception and treatment patterns of truncal acne.
Background: Prurigo nodularis (PN) is an intensively pruritic skin disease that negatively influences quality of life. Cryosim-1 (Intrinsic IB Spot) is a synthetic, selective transient receptor potential melastatin 8 agonist.
Aims: To investigate the efficacy and safety of cryosim-1 in PN patients.
The morphology of facial scars shows a wide variation in terms of texture and colour. To date, there are no reliable predictors of aberrant scarring. We conducted a retrospective analysis to identify factors associated with specific scar features and types.
View Article and Find Full Text PDFLymphoplasmacytic lymphoma (LPL) is a rare variant of non-Hodgkin lymphoma, accounting for <1% of cases. Skin involvement in LPL is quite rare-accounting for approximately 5% of extramedullary disease-and includes a variety of clinical morphologies, such as erythematous-to-violaceous plaques, violaceous nodules or tumors, and ulceration at various anatomical sites. Herein, we report the case of a 45-year-old Korean woman who presented with generalized erythematous indurated plaques and pendulous skin growths, which were asymptomatic, with marked diffuse infiltration of lymphocytes and plasma cells in the dermis.

Conventional treatments have several limitations regarding the alleviation of pigmentation and atrophy. We report two cases of Korean women with linear lichen planus pigmentosus on their faces who were successfully treated with fractional lasers and intralesional injection of polydeoxyribonucleotide.

The objective of this study was to assess the risk of autoimmune diseases in patients with newly diagnosed psoriatic disease. Using the Korean National Health Insurance Service database, patients with newly diagnosed psoriatic disease between 2007 and 2019 were included.

We investigated the differences in spatially resolved transcriptome profiles of MF-LCT and pcALCL using CD30 morphology markers and 28 and 24 regions of interest (ROIs) in MF-LCT and pcALCL, respectively. Differentially expressed genes, pathway analysis, and immune-cell deconvolution by selective analysis of CD30-positive tumor cells and CD30-negative extratumoral areas were undertaken.

Objective: To analyze the clinicopathological features of MCC and identify factors associated with its prognosis.
