Abstract
PURPOSE Few studies have investigated the impact of biologics on the risk of major adverse cardiovascular events (MACEs) among Korean patients with psoriatic diseases. 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. Follow-up data for MACEs and all-cause mortality between 2016 and 2020 were collected. A total of 2886 individuals were included, including 1987 IL-12/23 inhibitor users and 899 TNF-α inhibitor users. RESULTS Compared with IL-12/23 inhibitor users, TNF-α inhibitor users had a higher prevalence of dyslipidemia and a significantly higher risk of all-cause mortality but not MACE. After controlling for age, female TNF-α inhibitor users had a significantly increased risk of all-cause mortality. Meanwhile, after controlling for sex, TNF-α inhibitor users aged 60 years or older demonstrated a significantly elevated risk of all-cause mortality. In conclusion, No statistically significant difference in MACE risk was observed between patients who used TNF-α and IL-12/23 inhibitors. Nevertheless, the use of IL-12/23 inhibitors, especially among older and female patients, resulted in a lower overall mortality.

Abstract
BACKGROUND Acral lentiginous melanoma (ALM), a cutaneous melanoma subtype, exhibits a poorer prognosis than nonacral cutaneous melanoma (NACM). The neutrophil-to-lymphocyte ratio (NLR) is emerging as a prognostic indicator across diverse cancers. OBJECTIVE We explored the baseline NLR disparities between ALM and NACM, and the NLR's prognostic significance in patients with ALM. METHODS We reviewed records of patients with ALM and NACM diagnosed between 1997 and 2022, analyzing medical data. RESULTS Among 327 and 159 patients with ALM and NACM, respectively, baseline NLR varied based on distinct clinicopathologic factors between ALM and NACM. In stage 3 to 4 melanomas, the median NLR for ALM (2.18; IQR, 1.70-3.08) significantly surpassed NACM (1.74; IQR, 1.33-2.53) (P = .029). In patients with ALM, high NLR (hazard ratio, 1.64; 95% CI, 1.02-2.66; P = .043) was independently correlated with poor progression-free survival when adjusting for ulceration, Breslow thickness of ≥2 mm, and nodal invasion. LIMITATIONS Single-center, retrospective design. CONCLUSION Advanced-stage ALM exhibited a significantly higher baseline NLR compared with that of NACM. Evaluating baseline NLR could provide valuable prognostic insights for patients with ALM.

Abstract
BACKGROUND Daily usage of facial masks during coronavirus disease 2019 pandemic influenced on facial dermatoses. OBJECTIVE This study investigated the impact of mask-wearing habits on facial dermatoses. METHODS A nationwide, observational, questionnaire-based survey was conducted from July through August 2021, involving 20 hospitals in Korea. RESULTS Among 1,958 facial dermatoses, 75.9% of patients experienced aggravation or development of new-onset facial dermatoses after wearing masks. In aggravated or newly developed acne patients (543 out of 743), associated factors were healthcare provider, female gender, and a long duration of mask-wearing. Irritating symptoms, xerosis, and hyperpigmentation were more frequently observed in this group. Aggravated or newly developed rosacea patients (515 out of 660) were likely to be female, young, and have a long duration of mask-wearing per day. Seborrheic dermatitis patients who experienced aggravation or de novo development (132 out of 184) were younger, and they more frequently involved the chin and jaw in addition to the nasolabial folds and both cheeks. Contact dermatitis patients (132 out of 147) with aggravation or de novo development tended to be female, involve both cheeks, and complain of pruritus. Aggravated or newly developed atopic dermatitis patients (165 out of 224) were more likely to be female, and had a higher baseline investigator global assessment score before mask-wearing. CONCLUSION Clinical features and factors related to aggravation were different according to the types of facial dermatoses.

Abstract
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. Photographs and medical records of 428 patients with facial scars were retrospectively reviewed. Patients with keloids were excluded. The mean age of the patients was 45.43 ± 23.13 years with a male-to-female ratio of 1:1.36. Atrophic scars were the most common (42.8%), followed by flat scars (38.7%) and hypertrophic scars (18.5%). Scars on the forehead were more likely to be atrophic, whereas scars on the chin/jaw and around the mouth were more likely to be hypertrophic. Hypopigmentation was significantly more common in scars located on the forehead. Redness (erythema) was significantly more common in scars located on the chin/jaw. Old scars were less likely to be erythematous, and hypertrophic. Atrophic scars were more common in younger patients. Scars caused by dermatologic conditions, such as acne, were more likely to be atrophic, whereas surgical scars had the lowest risk of being atrophic or hypertrophic. In conclusion, the location, onset, and cause of facial scars were associated with specific features of scars.

Abstract
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. PATIENTS/METHODS A randomized, double-blinded, placebo-controlled clinical trial including 30 patients was conducted. The numerical rating scale (NRS) of pruritus was evaluated before and 2 h after cryosim-1 application at every visit. RESULTS At week 8, the mean pruritus NRS before serum application (4.7 ± 0.4 treatment, 6.1 ± 0.5 placebo; p = 0.045) and 2 h after serum application (2.8 ± 0.4 treatment, 4.3 ± 0.5 placebo; p = 0.031) were significantly lower in the treatment group, and the mean NRS for sleep disorder was significantly lower in the treatment group (2.2 ± 0.5 treatment, 4.2 ± 0.8 placebo; p = 0.031). The mean satisfaction scales for pruritus improvement were significantly higher in the treatment group (7.2 ± 0.6) than in the placebo group (4.0 ± 0.9; p = 0.005). There was no difference in TEWL between the two groups, and no adverse reactions were reported. CONCLUSIONS Cryosim-1 is a safe and effective topical treatment for PN patients.

Abstract
Although various comorbidities have been noted to be associated with atopic dermatitis (AD) and psoriasis, few studies have compared comorbidities between the two diseases, and little is known about whether these comorbidities vary by the subtypes of psoriasis. In this study of 1:1 age- and sex-matched pair analysis between patients diagnosed with either psoriasis or AD at Asan Medical Center between 1991 and 2020, comorbidities, as determined by the International Classification of Diseases-10 codes, and likelihood ratios of metabolic and neurologic comorbidities in psoriasis compared with AD were studied using a logistic regression model. Among a total of 14,128 patients, the psoriasis group had higher odds of obesity (odds ratio [95% confidence interval]: 1.49 [1.34-1.66]), hypertension (1.14 [1.03-1.26]), diabetes mellitus (1.46 [1.29-1.66]), chronic kidney disease (1.59 [1.22-2.08]), and Parkinson's disease (2.1 [1.15-3.83]) than the AD group. Subgroup analysis revealed that patients with plaque psoriasis had higher odds of obesity (1.18 [1.05-1.33]), hypertension (1.18 [1.06-1.32]), diabetes mellitus (1.53 [1.34-1.75]), chronic kidney disease (1.66 [1.26-2.17]), and Parkinson's disease (2.12 [1.16-3.88]) compared with AD. Meanwhile, guttate psoriasis was associated with higher odds of dementia (3.63 [1.06-12.40]) and patients with generalized pustular psoriasis showed higher odds of diabetes mellitus (5.42 [1.56-18.83]) compared with AD. In conclusion, Asian patients with all types of psoriasis should be closely monitored for the development of metabolic and neurologic diseases, especially men and those aged ≥ 40 years.

Abstract
The psoriasiform manifestation of mycosis fungoides (MF) was identified in 17.5% of patients in this study. Psoriasiform MF had a shorter prediagnosis period than the other subtypes. Psoriasiform MF was associated with advanced stage, lymph node involvement and large cell transformation, and was thus also associated with poor survival.

Abstract
Mycosis fungoides with large-cell transformation (MF-LCT) occurs in a minor proportion of aggressive lesions, which express CD30 similar to primary cutaneous anaplastic large-cell lymphoma (pcALCL). 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. In CD30-positive ROIs of MF-LCT, 190 differentially expressed genes were upregulated (29 were directly or indirectly associated with extracellular matrix remodeling), whereas 255 differentially expressed genes were downregulated, compared with those of pcALCL. Except for cornified envelope formation and keratinization, all six pathways enriched in CD30-positive ROIs of MF-LCT were associated with extracellular matrix remodeling. In CD30-positive ROIs in MF-LCT compared with those in pcALCL, immune-cell deconvolution revealed significantly increased fibroblasts and M2 macrophages (P = 0.012 and P = 0.023, respectively) but decreased M1 macrophages (P = 0.031). In CD30-negative ROIs in MF-LCT compared with those in pcALCL, memory B (P = 0.021), plasma (P = 0.023), and CD8 memory T (P = 0.001) cells significantly decreased, whereas regulatory T cells (P = 0.024) increased. Predomination of extracellular matrix remodeling pathways and immunosuppressive microenvironment in MF-LCT indicates pathophysiological differences between MF-LCT and pcALCL.

Abstract
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. METHODS We conducted two rounds of the Dephi technique to gather expert opinion and reach a consensus on truncal acne. The first round comprised 48 questionnaires focusing on various aspects such as epidemiology, clinical features, diagnosis, treatment, prognosis and more, while second rounds consisted of 26 questionnaires. RESULTS A total of 36 dermatologists (36/38 KARS members, 94.7%) completed this survey. In the first-round survey, consensus was reached on 20 out of the 48 questions (41.7%). In the second-round questionnaire, consensus was achieved on 9 of the 26 questions (34.6%). The most unresponsive lesion to truncal acne treatment was scars (atrophic/hypertrophic). The most commonly used treatments for each non-inflammatory and inflammatory truncal acne lesions were selected to use topical retinoids (78.1% of the responders) and oral antibiotics (93.8% of the responders). CONCLUSION Our study has yielded valuable insights into the epidemiology, clinical manifestations, diagnosis, treatment, and quality of life of patients with truncal acne. We anticipate that this study will inspire further comprehensive research for individuals with truncal acne.

Abstract
Lymphoplasmacytic 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. Immunohistochemical studies revealed that the lymphoid cells expressed CD3, CD79a, and cytoplasmic IgG, but lacked CD10 and IgM. Moreover, kappa light chain restriction and monoclonal immunoglobulin heavy chain gene rearrangement were observed. Upon further workup, lymphoma involvement was reported in multiple lymph nodes, including those in the cervical and axillary regions. This case shows a unique form of cutaneous LPL clinically presenting as acquired cutis laxa, emphasizing the dermatologists' need to be vigilant for variant forms of this disease.

Abstract
PURPOSE To assess cancer risks in patients with psoriasis and the effect of TNF-α inhibitor and interleukin (IL)-12/23 inhibitor therapy on those cancer risks. METHODS Using the Korean Health Insurance Review and Assessment Service database, patients with newly diagnosed psoriasis between 2008 to 2019 were included. Standardized incidence ratios (SIRs) of overall and specific cancers were calculated in patients with psoriasis. The effect of TNF-α inhibitor and IL-12/23 inhibitor exposure on the risk of cancers was assessed by multivariable Cox regression models. RESULTS In total, 191,678 patients with psoriasis were included in this study. The overall risk of cancer was significantly higher in patients with psoriasis than in the general population (SIR, 1.12; 95% confidence interval (CI), 1.09-1.14). TNF-α inhibitor users had a significantly higher risk for overall cancer (adjusted hazard ratio (aHR), 1.41; 95% CI 1.01-1.97). In contrast, IL-12/23 inhibitor exposure had a significantly lower risk for overall cancer (aHR, 0.57; 95% CI 0.37-0.87). Among specific cancers, the risks of non-Hodgkin lymphoma (aHR, 2.98; 95% CI 1.02-8.69) were increased by TNF-α inhibitor therapy, while the risk of other cancers, including nonmelanoma skin cancer (aHR, 2.31; 95% CI 0.51-10.46), was not significantly altered by TNF-α inhibitor therapy. CONCLUSION TNF-α inhibitor therapy in psoriasis is associated with a significantly increased risk of overall cancer and lymphoma, while the risk of solid organ cancer was not affected by this therapy. The IL-12/23 inhibitor is not associated with an increased risk of any cancer.

Abstract
There are limited large population-based cohort studies on the risk of incident autoimmune diseases among patients with newly diagnosed psoriatic disease. 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. Comparators were randomly selected and matched according to age and sex. A total of 321,354 patients with psoriatic disease and 321,354 matched comparators were included in this study. Patients with psoriatic disease had a significantly higher risk of Crohn's disease [adjusted hazard ratio (aHR), 1.95; 95% confidence interval (CI) 1.42-2.67], ulcerative colitis (aHR, 1.65; 95% CI 1.39-1.96), systemic lupus erythematosus (aHR, 1.86; 95% CI 1.34-2.57), rheumatoid arthritis (aHR, 1.63; 95% CI 1.52-1.76), ankylosing spondylitis (aHR, 2.32; 95% CI 1.95-2.77), alopecia areata (aHR, 1.41; 95% CI 1.35-1.46), and type 1 diabetes (aHR, 1.23; 95% CI 1.11-1.37). However, the risk of Graves' disease, Hashimoto's disease, Sjögren's syndrome, and systemic sclerosis was not significantly different between the groups. In conclusion, patients with newly diagnosed psoriatic disease may have a significantly increased risk of incident autoimmune diseases.

Abstract
BACKGROUND Merkel cell carcinoma (MCC) is an aggressive neuroendocrine tumor of the skin with high mortality. However, its clinical characteristics in Asian patients remain uncertain owing to its low incidence. OBJECTIVE To analyze the clinicopathological features of MCC and identify factors associated with its prognosis. METHODS The medical records of 62 patients with MCC were retrospectively reviewed. Data on clinical features, survival outcomes, prognostic factors, histopathology and immunohistochemical profile of the patients were collected and analyzed. Merkel cell polyomavirus status was evaluated using immunohistochemistry. RESULTS The incidence of MCC significantly increased over time. The mean duration of follow-up was 51.2 months, with an overall 5-year survival of 80.6%. More female patients with MCC were identified than male patients (1.3:1). Approximately half of the patients had stage I disease at the time of initial presentation. The primary tumor was frequently located in the lower extremities (40.3%), followed by the head and neck (32.3%), upper extremities (22.6%), and the trunk (4.8%). Male sex was associated with poorer overall survival (p = 0.003). Post-resection adjuvant radiotherapy significantly improved the overall survival (p = 0.023). Sentinel lymph node biopsy during surgery ameliorated the progression-free survival (p = 0.036) in patients with stage I or II cancer. Lymphovascular and perineural invasion were associated with a poor prognosis. Old age, immunohistochemical profiles, and Merkel cell polyomavirus-positivity were not associated with prognosis. CONCLUSION Post-surgical adjuvant radiotherapy and sentinel lymph node biopsy significantly improve the course of MCC.

Abstract
BACKGROUND Limited clinicopathological and prognostic data are available on hydroa vacciniforme (HV)-like lymphoproliferative diseases (HVLPD). METHODS This systematic review searched HVLPD reports in Medline via PubMed, Embase, Cochrane, and CINAHL databases in October 2020. RESULTS A total of 393 patients (65 classic HV, 328 severe HV/HV-like T-cell lymphoma [HVLL]) were analyzed. Among severe HV/HVLL cases, 56.0% were Asians, whereas 3.1% were Caucasians. Facial edema, hypersensitivity to mosquito bites, the onset of skin lesion, and percentage of severe HV/HVLL differed significantly by race. Progression to systemic lymphoma was confirmed in 9.4% of HVLPD patients. Death occurred in 39.7% patients with severe HV/HVLL. Facial edema was the only risk factor associated with progression and overall survival. Mortality risk was higher in Latin Americans than in Asians and Caucasians. CD4/CD8 double-negativity was significantly associated with the worst prognosis and increased mortality. CONCLUSION HVLPD is a heterogeneous entity with variable clinicopathological features associated with genetic predispositions.

Abstract
We have developed a new scintillator-based optical soft x-ray (OSXR) diagnostic system for KSTAR. By utilizing fiber optic faceplates, mm-size lens arrays, and fiber bundles, we have successfully constructed a novel optical system for scintillator-based soft x-ray detection to overcome the limited vacuum-port conditions in KSTAR. P47 (Y2SiO5), which has a fast rise (∼7 ns) and decay (∼100 ns) time sufficient for detecting plasma instabilities observed in the kHz-MHz spectral range, was selected as the scintillator material for the KSTAR OSXR system. Scintillation toward each detection channel is collected by the lens arrays coupled to optical fiber cores, which are connected to the photodetector system. Initial results obtained during the 2022 KSTAR experimental campaign support the validity of the OSXR data through the consistency of OSXR measurement results with other diagnostics. We also observe that the OSXR system can capture magnetohydrodynamic activities, such as sawtooth oscillations, and provide valuable information for disruption mitigation studies using shattered pellet injection.

Abstract
The diagnostic role of preferentially expressed antigen in melanoma (PRAME) immunohistochemistry has not been thoroughly evaluated for acral melanocytic tumors. The objective of this study was to evaluate the utility of this modality for the diagnosis of acral melanocytic tumors compared with other potential markers. Melanocytic tumors were classified as either acral nevi, challenging melanocytic tumors (superficial atypical melanocytic proliferation of uncertain significance (SAMPUS)-favor benign (SAMPUS-FB), SAMPUS-favor malignant (SAMPUS-FM)) or acral melanomas. A total of 106 acral melanocytic tumors including acral nevi (n = 32), SAMPUS-FB (n = 17), SAMPUS-FM (n = 20), and acral melanomas (n = 37) were included. Diagnostic power, assessed using an area under the receiver operating characteristic curve (AUC) for distinguishing acral melanomas and acral nevi, was highest for PRAME (AUC = 0.997), followed by c-Myc (AUC = 0.755), cyclin D1 (AUC = 0.652), and c-Kit (AUC = 0.573). At a PRAME expression level ≥30% as a positive test for acral melanoma, the sensitivity and specificity of this marker for discriminating acral melanoma from acral nevus were 100% and 96.9%, respectively. PRAME immunohistochemistry also discriminated SAMPUS-FM from SAMPUS-FB with a sensitivity and specificity of 90.0% and 76.5%, respectively. In conclusion, PRAME immunohistochemistry can be used effectively to distinguish between various spectra of acral melanocytic neoplasms.

Abstract
BACKGROUND Pyoderma gangrenosum is a rare autoinflammatory neutrophilic dermatosis that rapidly evolves. However, little is known about the clinicopathological features and prognosis of pyoderma gangrenosum. AIMS We aimed to document clinicopathologic and prognostic data of the patients with pyoderma gangrenosum. METHODS In this retrospective observational study, we reviewed case records of patients diagnosed with pyoderma gangrenosum between 1999-2019. RESULTS Fifty-three patients were identified by reviewing medical records for skin biopsy; of these, 37 were men and 16 were women. Mean age at onset was 43.3 ± 18.5 years. The most frequently affected area was the lower extremities (60.4%), followed by the head and neck (17.0%). The most common subtype was ulcerative (47.2%), followed by bullous (22.6%). 30 cases had underlying diseases and the most common were malignancy (24.5%), followed by inflammatory bowel diseases (18.9%). The proportion of cases with history of trauma were significantly higher in post-operative type (100%) as compared to the bullous type (8.3%). Histologic features of granulation tissue were frequently found in post-operative type (66.7%) and bullous type (58.3%). Granulomas were predominantly found in bullous type (58.3%). Age <60 years appeared to be significantly associated with multiple lesions. Partial-to-complete remission was observed in 40 cases (75.5%). Nine (17.0%) cases experienced recurrence with a median progression-free period of six months (interquartile range of 3.0-9.0 months). Cases with underlying hematologic disorders and the bullous subtype were significantly associated with early recurrence. LIMITATIONS This study was a single-centre study with a retrospective design. CONCLUSION Pyoderma gangrenosum appears to have ethnic differences. Underlying haematologic disorders and bullous subtype have a worse prognosis. However, the type of histopathology did not correlate with the clinical outcome of pyoderma gangrenosum.

Abstract
BACKGROUND Dermatofibrosarcoma protuberans (DFSP) is a rare fibrohistiocytic tumour of unknown pathogenesis with intermediate malignant potential. Although trauma has been hypothesized as a predisposing factor for DFSP development, clinicopathological characteristics of trauma-related DFSP have not been investigated. OBJECTIVE This study investigated the differences between trauma-associated DFSP and trauma-unrelated DFSP. METHODS Patients histopathologically diagnosed with DFSP from January 2000 to December 2019 at the Dermatology Department were included. Clinical, histopathological, prognostic features and trauma history were analysed. RESULTS We recruited 141 patients with DFSP (mean age, 36.1 years; male: female, 1:1.01). Recurrence and systemic metastasis were observed in 15.6% and 2.8% of patients, respectively. Older patients were likely to develop DFSP at the trauma sites more frequently on the face and lower legs. The active-growing lesions were more frequently associated with trauma-related DFSP. Multivariable logistic regression revealed that age at diagnosis (OR: 1.031; 95% CI: 1.004-1.059; p = 0.024) and tumour growth (OR: 3.336; 95% CI: 1.162-9.578, p = 0.025) were significantly associated with trauma-related DFSPs. CONCLUSIONS The age at diagnosis, lesion location and tumour growth were associated with DFSPs in this study. Analysis of DFSP with trauma history provides a deeper understanding of long-term trauma effects on sarcoma development.

Abstract
A new soft x-ray (SXR) array diagnostic system has been developed on versatile experiment spherical torus (VEST) for measurements of 2D SXR emissivity profile and identification of poloidal mode structure. Through tomographic inversion techniques, 2D SXR emissivity profile can be acquired from the line-integrated SXR data, which enables the visualization of mode structure of plasma instability, such as the magnetohydrodynamics mode. The SXR array diagnostic system consists of two 20-channel arrays positioned at the middle and the top on the same poloidal plane for horizontal and vertical lines of sight, respectively. Each array of the diagnostic system uses absolute extreme ultraviolet photodiode array as the detector. To apply appropriate filters (up to four) for different energy regimes without breaking the vacuum, a filter wheel and its rotatable vacuum feed-through are installed behind the pinhole. SXR data are acquired with a digitizer at the sampling rate of up to 125 MHz. Finally, we discuss initial measurement data obtained from Ohmic plasma in VEST.

Abstract
BACKGROUND Nail apparatus melanoma (NAM) is a subtype of cutaneous melanoma occurring at nail units and belongs to the acral lentiginous melanoma subgroup. Due to its unique anatomical structure to protect the acral site, mechanical trauma may have a clinicoprognostic impact on NAM. Therefore, we investigated the clinicoprognostic and histopathological characteristics of NAM according to the presence of trauma history prior to melanoma development. METHODS Clinicopathological and follow-up data of patients with NAM according to trauma history were obtained. RESULTS We included 87 patients with NAM, 21.8% of whom had a previous trauma history. Trauma-related NAMs were more likely to involve the toenail (p = 0.040), include a high proportion of amelanotic melanomas (p = 0.038) as well as nail bed tumor (p = 0.013), and have a longer time interval between the onset of nail change and confirmed diagnosis (p = 0.012). Moreover, survival analysis revealed that trauma-related NAMs more frequently showed progression in general (p = 0.034) and nodal metastasis (p = 0.047) and had worse prognosis in terms of progression-free survival (p = 0.004). CONCLUSION In conclusion, NAMs with previous trauma have unique clinicoprognostic characteristics. The specific clinicopathological features of NAMs according to trauma indicate that trauma may play a role in melanoma development.

Abstract
BACKGROUND The clinical and pathological features of lymphomatoid papulosis (LYP) are diverse. The objective of this study is to evaluate the clinical and pathological features associated with the prognosis and clinical course of LYP. PATIENTS AND METHODS The clinical and pathological features of LYP in a medical center database were retrospectively retrieved. RESULTS Overall, 58 LYP patients were included in the study. The mean age at diagnosis was 39.1 years and the female-to-male ratio was 1:1.2. More than two-thirds (40/58, 69.0%) of the patients showed a chronic and recurrent disease course. A longer pre-diagnosis duration (odds ratio (OR), 1.01; 95% confidence interval (CI), 1.00-1.03) was significantly associated with secondary lymphoma development. Lower extremity involvement (OR, 10.40; 95% CI, 1.17-92.28) and the absence of eosinophils in the lesions (OR, 11.28; 95% CI, 1.01-126.24) were found to be significantly associated with the chronic and recurrent course of LYP. CONCLUSION A longer pre-diagnosis duration is associated with secondary lymphoma, while a lower extremity involvement and the absence of lesional eosinophil infiltration are associated with the chronicity of LYP.

Abstract
In this study, the clinicopathologic features and survival outcomes of patients with hyperpigmented MF from a single tertiary referral center database were retrospectively evaluated. Hyperpigmented MF accounted for 10.9% (14/128) of all MF cases. The mean age at diagnosis was 46.9 years, and the female-to-male ratio was 1:1.3. Concurrent hypopigmented, ichthyosiform, and poikilodermatous lesions were detected in 21.4%, 14.3%, and 14.3% of the patients, respectively. Histopathologically, most patients (85.7%) showed interface change with pigment incontinence. Double negative (CD4- and CD8-) immunophenotypes were more frequent in patients with hyperpigmented MF (25%) than in those with other MF subtypes (9.8%). Most patients (85.7%) had early-stage disease at diagnosis. The survival outcomes did not differ significantly between hyperpigmented and other MF subtypes. In conclusion, hyperpigmented MF often accompanies other atypical MF variants and is frequently associated with atypical immunophenotypes. The outcomes of hyperpigmented MF are comparable to those of other MF subtypes.

Abstract
BACKGROUND/OBJECTIVES The clinical implications of facial involvement in pediatric patients with psoriasis have not been adequately studied. The objectives of this study are to evaluate the association between facial involvement and clinical features including disease severity of psoriasis in children and adolescents. METHODS The clinical features of patients aged below 20 years diagnosed with psoriasis were retrospectively evaluated and grouped based on the presence or absence of facial involvement at presentation. Demographic and clinical data were compared between groups. RESULTS Of the 175 patients, 110 patients (62.9%) had facial involvement of psoriasis at presentation. The group with facial involvement was significantly younger at disease onset (p = .032) and had a higher body mass index (BMI) (p = .043) and psoriasis area and severity index (PASI) score (p <.001). The severity of pruritus was significantly higher in the facial than in the non-facial group (p = .020). Involvement of the nose was associated with the highest disease severity as assessed by the PASI score and affected body surface area. A significantly higher number of treatment modalities were used in the facial group than in the non-facial group (p = .013). The BMI (odds ratio (OR), 1.39; 95% CI (confidence interval), 1.07-1.80) and PASI score (OR, 1.45; 95% CI, 1.03-2.03) were independent factors associated with facial involvement of psoriasis. CONCLUSIONS Facial involvement in psoriasis was associated with higher disease severity and more treatment modalities in children and adolescents.

Abstract
The association between psoriasis and alopecia areata has not been thoroughly investigated. The objective of this study is to investigate the association of psoriasis with alopecia areata. An electronic search was conducted in August 2021. The analysis included studies that reported sufficient data on the prevalence, odds, or hazard of alopecia areata in patients with psoriasis or that of psoriasis in patients with alopecia areata. Meta-analysis using an inverse variance method was performed with a random-effects model, assuming inherent heterogeneity between the included studies. The subgroup analyses were performed according to the age group and study quality. A total of 27 studies were included. The pooled prevalence of alopecia areata among patients with psoriasis was 0.5% (95% confidence interval [CI], 0.3-0.7%). The pooled odds ratio of alopecia areata among patients with psoriasis was 2.71 (95% CI, 2.29-3.21), whereas the pooled prevalence of psoriasis among patients with alopecia areata was 2.5% (95% CI, 2.0-3.0%). Moreover, the pooled odds ratio of psoriasis among patients with alopecia areata was 3.52 (95% CI, 1.27-9.74). The association of psoriasis and alopecia areata remained in the subgroup analyses according to the age group and study quality. In conclusion, this study suggests a bidirectional association between psoriasis and alopecia areata. Clinical examinations may be necessary to determine the presence of comorbid alopecia areata in patients with psoriasis and vice versa.

Abstract
BACKGROUND Distinguishing benign lesion from early malignancy in melanocytic lesions of the nail unit still remains a diagnostic challenge, both clinically and histopathologically. While several immunohistochemistry (IHC) stainings have been suggested to help discriminate benign subungual melanocytic proliferation (SMP) and subungual melanoma in situ (MIS), the diagnostic utility of IHC staining for cyclin D1 and PRAME has not been thoroughly investigated in melanocytic lesions of nail unit. METHODS This retrospective study included cases of benign SMP and subungual MIS confirmed by biopsy at Asan Medical Center from January 2016 to December 2020. Cases of melanocytic activation without proliferation and melanoma where dermal invasion was identified were excluded. Cyclin D1 and PRAME expression was assessed by counting proportion of melanocytes with nuclear positivity under 200x magnification. RESULTS A total of 14 patients with benign SMP and 13 patients with subungual MIS were included in this study. 11 patients with benign SMP (71.4%) and 5 patients with subungual MIS (38.5%) showed > 60% nuclear immunostaining for cyclin D1, respectively. While 13 patients with benign SMP (92.9%) showed totally negative staining for PRAME, 10 patients with subungual MIS (76.9%) exhibited > 50% nuclear immunostaining for PRAME. Using the cutoff of 10%, PRAME exhibited good overall discrimination between benign SMP and subungual MIS (AUC = 0.849, 95% CI = 0.659-0.957). CONCLUSIONS This study suggests that PRAME IHC staining as a reliable discriminator in distinguishing subungual MIS from benign SMP.

Abstract
A randomized trial (KCT0005614; https://cris.nih.go.kr) was conducted in a tertiary care institute in South Korea, to validate whether artificial intelligence (AI) could augment the accuracy of non-expert physicians in the real-world settings which included diverse out-of-distribution conditions. Four non-dermatology trainees and four dermatology residents examined the randomly allocated patients with skin lesions suspicious of skin cancer with or without the real-time assistance of AI algorithm (https://b2020.modelderm.com#world; convolutional neural networks). Using 576 consecutive cases (Fitzpatrick skin phototypes III or IV) with suspicious lesions out of the initial 603 recruitments, the accuracy of the AI-assisted group (n=295, 53.9%) was significantly higher than those of the Unaided group (n=281, 43.8%; P=0.019). The augmentation was more significant from 54.7% (n=150) to 30.7% (n=138; P<0.0001) in the non-dermatology trainees who had the least experience in dermatology. The augmentation was not significant in the dermatology residents. The algorithm could help the trainees in the AI-assisted group include more differential diagnoses than the Unaided group (2.09 diagnoses versus 1.95; P=0.0005). In this single-center, unmasked, paralleled, randomized controlled trial, the multiclass AI algorithm augmented the diagnostic accuracy of non-expert physicians in dermatology.

Abstract
BACKGROUND Although deep neural networks have shown promising results in the diagnosis of skin cancer, a prospective evaluation in a real-world setting could confirm these results. This study aimed to evaluate whether an algorithm (http://b2019.modelderm.com) improves the accuracy of nondermatologists in diagnosing skin neoplasms. METHODS A total of 285 cases (random series) with skin neoplasms suspected of malignancy by either physicians or patients were recruited in two tertiary care centers located in South Korea. An artificial intelligence (AI) group (144 cases, mean [SD] age, 57.0 [17.7] years; 62 [43.1%] men) was diagnosed via routine examination with photographic review and assistance by the algorithm, whereas the control group (141 cases, mean [SD] age, 61.0 [15.3] years; 52 [36.9%] men) was diagnosed only via routine examination with a photographic review. The accuracy of the nondermatologists before and after the interventions was compared. RESULTS Among the AI group, the accuracy of the first impression (Top-1 accuracy; 58.3%) after the assistance of AI was higher than that before the assistance (46.5%, P = .008). The number of differential diagnoses of the participants increased from 1.9 ± 0.5 to 2.2 ± 0.6 after the assistance (P < .001). In the control group, the difference in the Top-1 accuracy between before and after reviewing photographs was not significant (before, 46.1%; after, 51.8%; P = .19), and the number of differential diagnoses did not significantly increase (before, 2.0 ± 0.4; after, 2.1 ± 0.5; P = .57). CONCLUSIONS In real-world settings, AI augmented the diagnostic accuracy of trainee doctors. The limitation of this study is that the algorithm was tested only for Asians recruited from a single region. Additional international randomized controlled trials involving various ethnicities are required.

Abstract
BACKGROUND There are limited data regarding the difference in progression pattern between acral melanoma and nonacral melanoma. AIMS The objectives of this study were to compare the progression pattern between acral and nonacral melanoma and evaluate its impact on clinical outcomes. METHODS Clinical and histopathological features, survival outcomes and prognostic factors of 492 patients with acral melanoma or nonacral melanoma were retrospectively evaluated using the Asan Medical Center database. RESULTS The male-to-female ratio and the mean age was 1:0.92 and 60.2 years for acral melanoma (n = 249), and 1:0.85 and 58.4 years for nonacral melanoma (n = 243), respectively. The demographic difference was not significant. Although prediagnosis duration was longer and the advanced stage was more common in acral melanoma than that in nonacral melanoma, the vertical growth phase was more common in nonacral melanoma than that in acral melanoma, whereas, the horizontal diameter is longer in acral melanoma than that in nonacral melanoma. Dissemination to lymph nodes was more common in acral melanoma than that in nonacral melanoma. Lymph node involvement was associated with deeper Breslow thickness in nonacral melanoma but not in acral melanoma. The degree of correlation of prediagnosis duration with horizontal diameter was remarkable in acral melanoma, but with Breslow thickness in nonacral melanoma. Overall survival was worse in acral melanoma than that in nonacral melanoma. The prognostic value of Breslow thickness was more remarkable in nonacral melanoma than that in acral melanoma. LIMITATIONS This study is a retrospective, single-center design. CONCLUSION Acral melanoma has a longer radial growth phase compared with nonacral melanoma. However, acral melanoma is commonly associated with lymph node dissemination which contributed to worse survival in acral melanoma than nonacral melanoma.

Abstract
Background Epidermal growth factor receptor (EGFR) is overexpressed in many cancers. However, EGFR expression in melanoma and its role are conflicting. Objective This study aimed to evaluate EGFR expression in distant metastatic melanoma and analyze its relationship with histologic and clinical characteristics and survival. Methods Diagnostic tissues from 55 cases of distant metastatic melanoma was evaluated by immunohistochemistry for EGFR expression. Clinicopathologic features and survival outcomes were analyzed according to EGFR expression. Results The positive EGFR expression in distant metastatic melanoma was significantly correlated with the absence of ulceration. The EGFR expression in distant metastatic melanoma was significantly associated with poor survival, under the conditions of male sex and primary cutaneous melanoma without ulceration or Breslow thickness ≤4.0 mm. This study bears limitations of a retrospective study in a single institution. Conclusion EGFR immunostaining had predictive values for survival outcome. The EGFR expression in distant metastatic melanoma in male, no ulcer, or Breslow thickness ≤4.0 mm appeared to be involved in disease progression.

Abstract
With the increasing incidence of skin cancer, many noninvasive technologies to detect its presence have been developed. This review focuses on reflectance confocal microscopy (RCM), optical coherence tomography (OCT), high-frequency ultrasound (HFUS), electrical impedance spectroscopy (EIS), pigmented lesion assay (PLA), and Raman spectroscopy (RS) and discusses the basic principle, clinical applications, advantages, and disadvantages of each technology. RCM provides high cellular resolution and has high sensitivity and specificity for the diagnosis of skin cancer. OCT provides lower resolution than RCM, although its evaluable depth is deeper than that of RCM. RCM and OCT may be useful in reducing the number of unnecessary biopsies, evaluating the tumor margin, and monitoring treatment response. HFUS can be mainly used to delineate tumor depths or margins and monitor the treatment response. EIS provides high sensitivity but low specificity for the diagnosis of skin malignancies. PLA, which is based on the genetic information of lesions, is applicable for the detection of melanoma with high sensitivity and moderate-to-high specificity. RS showed high accuracy for the diagnosis of skin cancer, although more clinical studies are required. Advances in these technologies for the diagnosis of skin cancer can lead to the realization of optimized and individualized treatments.

Abstract
Importance Comprehensive data on childhood mycosis fungoides (MF) is scarce. Objective To describe clinical features, immunophenotypes, various treatment options, and prognosis of MF in children and adolescents. Evidence Review This systematic review searched MEDLINE via PubMed, Embase, Cochrane, and Scopus databases in October 2019. The search terms included mycosis fungoides, infant, children, and adolescent. No filter for the publication period was used, but studies written in a language other than English were excluded. Reference lists of the relevant articles were also searched manually. Case series and case reports were included if data on childhood MF were extractable. The Asan Medical Center database for cases of childhood MF was also searched. Patients were treated from January 1, 1990, to July 31, 2019, and were younger than 20 years at the time of diagnosis. The methodologic quality of the included studies was assessed with items from the Newcastle-Ottawa scale. Data were analyzed from December 9, 2019, to September 4, 2020. Findings A total of 571 unique patients were included. The mean (SD) age at diagnosis was 12.2 (4.2) years; at onset, 8.6 (4.2) years. The female-to-male ratio was 1:1.6 (350 male patients [61.3%]). Among 522 patients with data available at diagnosis, stage 1 disease constituted 478 cases (91.6%), followed by stage 2 (39 [7.5%]) and stage 4 (5 [1.0%]). Among the 567 patients with data available, the most common variant of MF was the hypopigmented form (309 [54.5%]), followed by classic MF (187 [33.0%]). The MF lesions were predominantly the CD4+ and CD8+ immunophenotype in 99 (49.5%) and 79 (39.5%) of 200 patients, respectively. Among the treatments, narrowband UV-B was the most frequently used (150 of 426 [35.2%]). Most patients were alive with the disease (185 of 279 [66.3%]); 83 of 279 (29.8%) were in complete remission; and 11 of 279 (3.9%) had died by the last follow-up. A longer time from onset to diagnosis (hazard ratio [HR], 1.24; 95% CI, 1.06-1.45), granulomatous slack skin (HR, 12.25; 95% CI, 1.99-75.26), granulomatous MF (HR, 14.59; 95% CI, 1.31-162.00), a history of organ transplant (HR, 10.15; 95% CI, 0.98-105.37), and stage 2 disease at the time of diagnosis (HR, 10.22; 95% CI, 2.94-35.50) were associated with worse outcomes. Conclusions and Relevance The findings of this review suggest that there is often a significant delay until the establishment of a correct diagnosis of childhood MF, which may be detrimental to the prognosis.

Abstract
We aimed to evaluate the efficacy and safety of a fractional microneedle radiofrequency device (FMRD) for the treatment of primary axillary hyperhidrosis (PAH). The FMRD adopted insulated microneedles, which could be located at a depth of up to 4.5 mm and deliver a radiofrequency current in a fractional manner. Also, the device could automatically regulate the amount of the delivered energy. Sixteen Korean patients with PAH received two FMRD treatment sessions at a 3-week interval and were followed-up until week 15. The primary outcome was Patient Satisfaction Scale (PSS) score at each visit. Hyperhidrosis Disease Severity Scale (HDSS) and Global Aesthetic Improvement Scale (GAIS) were also assessed. The area and amount of sweat produced were evaluated by specific tests. Mean PSS score significantly improved from 1.6 at week 3 to 2.5 at week 15 by 56%. More than a 50% improvement in sweating assessed by the PSS score was seen in 63% and 50% of patients at weeks 11 and 15, respectively. Mean HDSS score significantly decreased by week 3 and further decreased by week 7. Mean GAIS scores improved from the first follow-up visit at week 3 and improved again at week 7. The mean hyperhidrosis area assessed by starch-iodine test significantly decreased by 36% at week 15 compared with baseline. Mean transepidermal water loss level significantly decreased by 42% at week 15 compared with baseline. No patients experienced any serious adverse events. FMRD can be an effective and safe treatment modality for PAH.

Abstract
Comprehensive studies of primary cutaneous extranodal natural killer/T-cell lymphoma (PCENKTL) are scarce. The objectives of this study are to describe PCENKTL in terms of its clinical features, histopathology, immunophenotypes, and prognosis, and to analyze factors affecting patient survival outcomes. We searched four databases and include studies with extractable data. We also searched the Asan Medical Center database for cases of PCENKTL. We include a total of 289 patients. The mean age at diagnosis was 52.8 years and the female to male ratio was 1:1.2. The most common clinical morphology was a subcutaneous nodule, followed by ulceration. About half of the patients presented with disseminated skin lesions. The median overall survival was 12.0 months and the 5-year survival rate was 22.0%. There was no correlation between the clinical morphology or the histopathological features of the skin lesions with the patient outcomes. Advanced TNM stage, a disseminated skin lesion, tumor location on the leg or trunk, the presence of B symptoms, and a high International Prognostic Index score were associated with a worse prognosis, and chemoradiotherapy was associated with a better survival outcome as compared with chemotherapy alone in univariable analyses. In multivariable analyses, only advanced TNM stage and tumor location on the leg were associated with a worse prognosis. In conclusion, PCENKTL is an aggressive cutaneous lymphoma and its prognosis is associated with TNM stage and tumor location.

Abstract
BACKGROUND Partial unilateral lentiginosis (PUL) is a rare acquired circumscribed hyperpigmentation characterized by multiple simple lentigines involving half of the body. Since the previous studies of PUL were mostly based on case reports and the current literature lacks well-designed retrospective studies that involve a large number of cases, PUL is not a well-defined entity, and differential diagnosis with nevus spilus is still difficult. This study aims to evaluate clinical and histopathological characteristics and treatment outcomes of PUL on head and neck area of Koreans. METHODS Thirty-two patients with PUL on head and neck area were diagnosed clinicohistopathologically at the Asan Medical Center from 2004 to 2017. Their medical records, photographs, and biopsy specimens were reviewed, and immunohistochemical staining for protein kinase C (PKC)-βΙΙ was evaluated for melanogenic activity. RESULTS Four patients (12.5%) of PUL had congenital lesions, and 24 (75.0%) had age of onset younger than 10 years. Confluency of lentiginous lesions (100%) and mild to moderate background interlesional hyperpigmentation (90.6%) were observed. The lentiginous lesions showed increased melanocytes, melanophages, basal melanins, lentiginous hyperplasia, and perivascular inflammatory cells compared with background interlesional hyperpigmentation, and PKC-βΙΙ was focally positive in 7 of 12 stained PUL lesions. Among the 16 patients who received laser treatments, 10 (62.5%) showed more than 50% of improvement. CONCLUSIONS The findings of this study will allow for improved diagnosis of PUL and understanding of its features, which may facilitate proper management in the future.

Abstract
BACKGROUND Mycosis fungoides (MF) shows racial and regional differences in terms of clinical features. The availability of therapeutic options as well as drugs differs from one country to another. There are only limited data on the clinical characteristics and treatment experience of MF from South Korea. METHODS Medical records of 97 patients with MF were retrospectively analyzed to investigate clinical features, survivals, and prognostic factors. Assessment of prognostic variables was done using univariate Cox proportional hazard models. RESULTS Median age at time of diagnosis was 45 years. The median time from onset of skin lesion to diagnosis of MF was 36 months with a median follow-up period of 96 months. A number of clinical variants of MF were observed. Treatment mainly consisted of narrow-band UVB, systemic retinoids, methotrexate, chemotherapy, and regional radiotherapy. Complete remission was observed in 78% of patients with records on their clinical course. About 12% experienced disease progression. No clinical prognostic factor apart from TNM staging was identified. CONCLUSION Despite delay in diagnosis, most cases of MF in Korea were diagnosed in early stages. Prognosis of our patients was more favorable than those of other geographic regions as reported in previous studies. Good response to treatment, consisting mainly of phototherapy and radiation therapy, and relatively indolent clinical behavior of disease were observed in this homogeneous cohort of Korean patients with MF.

Abstract
A fast-ion Dα (FIDA) diagnostics system was installed for core and edge measurements on KSTAR. This system has two tangential FIDA arrays that cover both blue- and redshifted Dα lines (cold: 656.09 nm) in active views along the neutral beam 1 A centerline. The spectral band is 647-662.5 nm, and it covers the Doppler shift of the emission from the maximum energy of the neutral beam (100 keV). A curved filter strip with a motorized stage adequately prevents saturation of the electron multiplying charge-coupled device signal by the cold Dα line from the plasma edge. From comparisons of the measured spectra and FIDASIM modeling code, the FIDA spectra are well matched quantitatively. Moreover, the first measurements show that the FIDA radiance agrees with the neutron rate in the time trace during external heating and perturbation. In addition, responses are observed in the core FIDA radiance during the edge-localized mode cycle.

Abstract
Inflammatory skin diseases, such as rosacea and acne, are major causes of facial erythema and accompanying skin barrier dysfunction. Several methods to restore the impaired skin barrier and improve facial erythema, such as medication, radiofrequency, laser, and ultrasound therapy were attempted. This study evaluated the efficacy and safety of dual-frequency ultrasound with impulse mode, for improving skin hydration and erythema in Asian subjects with rosacea and acne. Twenty-six subjects with facial erythema received an ultrasound treatment once per week, for 4 weeks, over both cheeks. The erythema index and transepidermal water loss (TEWL) were measured at each visit. Clinicians assessed the erythema improvement and patients evaluated their satisfaction level. The average decrease in TEWL and erythema index at 6 weeks was 5.37 ± 13.22 g·h−1·m−2 (p = 0.020) and 39.73 ± 44.21 (p = 0.010), respectively. The clinician’s erythema assessment and the subject satisfaction questionnaire score significantly improved at final follow-up (p < 0.001; p = 0.003, respectively). No serious adverse effects were observed during the treatment and follow-up periods. The dual-frequency ultrasound with impulse mode appears to be effective and safe for improving skin hydration and erythema in patients with rosacea and acne.

Abstract
Importance Large population-based studies investigating the risks of overall and specific cancers among patients with hidradenitis suppurativa (HS) are limited. Objective To assess the overall and specific cancer risks in patients with HS compared with the risks in patients without HS in the Republic of Korea. Design, Setting, and Participants A nationwide population-based cohort study, using the Korean Health Insurance Review and Assessment Service database was conducted over a 2-year period from January 1, 2007, to December 31, 2008. Individuals in the control group who were never diagnosed with HS or cancer during the washout period were randomly extracted and matched by age, sex, index year, and insurance type at a case-control ratio of 1:8, and patients with newly diagnosed HS between January 1, 2009, and December 31, 2017, were included. Follow-up data on incident cancer from January 1, 2009, to December 31, 2018, were included. Main Outcomes and Measures The overall and specific cancer incidence rates were calculated per 100 000 person-years in patients with HS and in the matched control cohort. The risk for cancers was assessed by multivariable Cox regression models in patients with HS compared with the matched control cohort. Results In total, 22 468 patients with HS and 179 734 matched controls were included in the study. The mean (SD) age was 33.63 (17.61) years and 63.7% of the participants in both groups were male. The adjusted hazard ratio (aHR) of overall cancer in patients with HS was 1.28 (95% CI, 1.15-1.42). Patients with HS had significantly higher risk for Hodgkin lymphoma (aHR, 5.08; 95% CI, 1.21-21.36), oral cavity and pharyngeal cancer (aHR, 3.10; 95% CI, 1.60-6.02), central nervous system cancer (aHR, 2.40; 95% CI, 1.22-4.70), nonmelanoma skin cancer (HR, 2.06; 95% CI, 1.12-3.79), prostate cancer (aHR, 2.05; 95% CI, 1.30-3.24), and colorectal cancer (aHR, 1.45; 95% CI, 1.09-1.93). Conclusions and Relevance In this study, HS appeared to be associated with a significantly increased risk of overall cancer as well as several specific cancers.

Abstract
BACKGROUND Kaposi sarcoma (KS) is a mesenchymal tumor with distinct histopathological features according to stage of progression. Programmed death-1 (PD-1) and its ligand PD-L1 play major roles in the immune escape strategy of tumors. OBJECTIVES This study evaluated expression of PD-1 and PD-L1 in various stages of KS and investigated associations between their expression and clinical characteristics. METHODS Fifty cases with histopathologically diagnosed KS were classified as early or late stage. These specimens were stained with anti-PD-1 and anti-PD-L1 antibodies. The extent of expression in the intratumoral and peritumoral areas was judged by two dermatopathologists. RESULTS PD-1 and PD-L1 were expressed in 72.2% (13/18) and 11.1% (2/18) of early-stage cases, respectively, compared with 43.8% (14/32) and 28.1% (9/32) of late-stage cases, respectively. At the late stage, PD-1 expression was significantly higher in the peritumoral area than in the intratumoral area (P = 0.001). PD-1 expression in the intratumoral area was significantly higher at the early stage than at the late stage (P = 0.013). PD-L1 expression in the peritumoral area was significantly higher at the late stage than at the early stage (P = 0.038). CONCLUSIONS The pattern of PD-1 and PD-L1 expression differs according to the stage of KS, but is unaffected by clinical variables.
