RESUMEN
BACKGROUND: Patients with Mycosis Fungoides (MF)/Sézary Syndrome (SS) can experience impacted health-related quality of life (HRQoL). OBJECTIVES: To validate the CTCL-S, a novel subscale of the Functional Assessment of Cancer Therapy - General (FACT-G), in patients with MF/SS. METHODS: Qualitative interviews were conducted with expert clinicians and MF/SS patients. Thematic analysis identified the most common concerns, and 19 items were selected.MF/SS patients were recruited from a single center. FACT-G, CTCL-S (collectively "FACT-CTCL"), Skindex29, and Visual Analogue Scale-Pruritis (VAS itch) were administered. A subset repeated FACT-CTCL and VAS itch after ≈2 weeks. Patient demographics and clinical characteristics were obtained via review of the electronic medical record.Psychometric properties were assessed. Internal consistency was estimated using Cronbach's alpha (α). Convergent and discriminant validity were assessed by comparing CTCL-S to disease stage, age, VAS itch, FACT-G, and SkinDex29. Exploratory factor analysis (EFA) was used to preliminarily assess CTCL-S dimensionality. Test-retest repeatability was summarized using intraclass correlation coefficient (ICC), within-subject standard deviation (wSD), and within-subject coefficient of variation. RESULTS: Seventy-two patients completed the initial survey, and 35 repeated the FACT-CTCL and VAS itch after ≈2 weeks. Two-thirds were male, most were white (78%). The majority (85%) had MF, 15% SS, and 75% early (stage IA-IIA) and 25% advanced (≥ stage IIB) disease. Preliminary EFA found a single predominant factor, supporting a hypothesis of unidimensionality of the CTCL-S. Internal consistency of the CTCL-S was high (α: 0.95 [95% CI: 0.93-0.96]). There was no significant change in CTCL-S average test-retest scores (ICC of 0.93 (p = 0.63)). CTCL-S was significantly lower in advanced vs early stage disease (median[IQR]: 34[26, 48] vs. 59[44, 68], p < 0.001) and strongly correlated with VAS itch (Spearman's r (rs): -0.70, 95% CI: -0.81, -0.55), FACT-G (rs: 0.77, 95% CI: 0.65, 0.85), and Skindex29 (rs: -0.90, 95% CI: -0.94, -0.84), supporting convergent validity. CTCL-S scores had little correlation with age (rs: 0.19, 95% CI: -0.05, 0.41, p = 0.12), supporting discriminant validity. CONCLUSIONS: The FACT-CTCL is a disease specific instrument for assessing HRQoL with high reproducibility and good performance in a cohort of patients with MF/SS.
RESUMEN
Cutaneous graft versus host disease (cGVHD) has substantial clinical and histopathologic overlap with erythema multiforme (EM), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). This overlap can make it difficult to distinguish these disorders in patients who have received hematopoietic transplants. We sought to evaluate the utility of Dp I/II immunohistochemical stain in differentiating EM/SJS/TEN and cGVHD in a large cohort. Skin biopsy specimens from patients with cGVHD (n = 58) and EM/SJS/TEN (n = 60) were evaluated for Dp I/II expression by immunohistochemistry. We found a statistically significant difference in Dp I/II staining between cGVHD (all grades) and EM/SJS/TEN (mean scores 1.62 and 2.14, respectively; p < 0.005), as well as between Grades 2 + 3 cGVHD and EM/SJS/TEN (mean scores 2.26 and 1.62, respectively; p < 0.005), while we did not find a significant difference between Grade 4 cGVHD and EM/SJS/TEN (mean scores 1.69 and 1.62, respectively; p = 0.71). Dp I/II immunostain may be useful for differentiating EM/SJS/TEN from Grade 2 and Grade 3 cGVHD, especially in clinically ambiguous cases without extracutaneous GVHD.

The diagnosis of cutaneous T-cell lymphoma (CTCL) remains challenging. Demonstration of a clonal T-cell population using T-cell receptor (TCR) gene rearrangement studies by next-generation sequencing (NGS) has been explored in several studies. This review summarizes the current literature on NGS-based sequencing methods for the assessment of TCR clonality in the evaluation of atypical cutaneous lymphoid infiltrates and CTCL on behalf of the American Society of Dermatopathology Appropriate Use Criteria Committee (lymphoproliferative subgroup). PubMed was searched for relevant articles, including CTCL and NGS, for clonality from 1967 to 2022. Thirteen studies were included in the analysis. The skin was the most commonly assayed compartment with TCR NGS. Sensitivity for TCR NGS in the skin ranged between 69% and 100%, compared to 44%-72% for polymerase chain reaction (PCR)-capillary electrophoresis. Specificity for TCR NGS in the skin ranged from 86% to 100%, compared to 77%-88% for PCR capillary electrophoresis. TCR NGS was also reported to have potential prognostic value in CTCL and can also be used to detect relapse and/or minimal residual disease after treatment.
RESUMEN
INTRODUCTION: Pyoderma gangrenosum (PG) is a rare ulcerative skin condition with an increased risk of mortality compared to the general population. The causes of this increased risk are not well understood. Misdiagnosis is common in PG, and many studies are limited by the inclusion of misdiagnosed cases. The goal of this study was to review autopsy findings, identify causes of death, and identify factors that may worsen outcomes among deceased patients confirmed to have PG. METHODS: Data was retrospectively reviewed from the electronic medical records at five academic hospitals. A search was conducted for deceased patients with a diagnosis of PG who had an autopsy performed between 2010 and 2020. We report a descriptive analysis of 11 patients and their clinical characteristics, causes of death, and autopsy findings. RESULTS: The average age of death was 62.9 years. Seven patients had at least one underlying condition known to be associated with PG including inflammatory bowel disease, inflammatory arthritis, or a hematologic disorder. The most common cause of death was infection (n = 6, 54.5%), followed by pulmonary embolism (n = 3, 27.3%), and myelodysplastic syndrome (n = 2, 18.2%). Six patients (54.5%) were taking systemic steroids at the time of death. CONCLUSION: The development of PG may shorten life expectancy among those with underlying conditions associated with PG, and common treatments for PG may contribute to the risk of fatal complications. Awareness of the risk of infection, thrombosis, and malignancy among those with PG is necessary for proper management. Further research is needed to explore the relationship between PG and thromboembolism.

BACKGROUND: Ongoing controversy exists regarding terminology used to describe atypical melanocytic nevi. Efforts to standardize nomenclature, including the 1992 NIH consensus conference, have been largely unsuccessful. Significant advances have revealed an increasingly detailed genetic picture of melanocytic neoplasms, including strong evidence for the existence of those with "intermediate" behavior. METHODS: We sent an electronic survey to dermatopathologists (n = 846) to assess trends in nomenclature usage and attitudes toward developing new consensus nomenclature for atypical melanocytic nevi. RESULTS: There were 229 complete responses (27.1% response rate). The most used/preferred nomenclature was "dysplastic nevus" (43%/39%, respectively), followed by the NIH-recommended terminology (28%/26%). Three-tier grading systems were most heavily used/preferred (79%/63%). Dermatopathologists based in New England were most likely to use the NIH terminology; on the other hand, "dysplastic nevus" or "other" were most used elsewhere (p = 0.029). Most (76%) expressed at least "moderate" enthusiasm for developing consensus nomenclature, with 47% "very" or "extremely" enthusiastic. CONCLUSION: Little has changed with the wide variation in terminology for atypical melanocytic nevi. There continues to be no one dominant terminology in use. However, there is enthusiasm for standardization. A new attempt at updated consensus nomenclature may be fruitful.

Calciphylaxis is an uncommon but devastating disorder characterized by vascular calcification and subsequent cutaneous tissue necrosis. This results in exquisitely painful and slow healing wounds that portend exceptionally high morbidity and mortality. The diagnosis of this condition can be complicated because there are no conclusive serologic, radiographic or visual signs that this disease is manifesting. The differential of tissue necrosis is broad, and identifying calciphylaxis requires an adroit understanding of the risk factors and physical signs that should raise suspicion of this condition. Reviews on this subject are uncommon and lack directed commentary from disease experts on the best diagnostic approach for patients suffering from this disease. The goal of this article is to update practicing dermatologists on the current standard of care for calciphylaxis.

Several mutations and gene fusions involved in the mitogen-activated protein kinase (MAPK) pathway have been reported in histiocytic neoplasms including Langerhans cell histiocytosis and non-Langerhans-cell histiocytosis (NLCH). We identified a GAB2::BRAF fusion in a cutaneous lesion from a 22-year-old woman who presented with central diabetes insipidus and red/brown papules on her face, oral mucosa, axilla, and groin. Skin biopsy showed a CD68+, S100-, and CD1a- histiocytic proliferation consistent with NLCH, best clinically classified as xanthoma disseminatum. Next-generation sequencing identified a GAB2::BRAF fusion involving exon 2 of GAB and exon 10 of BRAF. This case implicates a novel fusion in the MAPK signaling pathway, not previously reported in histiocytic neoplasms, as a possible driver of NLCH. Our findings underscore the utility of performing molecular studies on skin biopsy specimens with NLCH to help identify potential targets for therapy.

ABSTRACT: We report a case of an unusual and aggressive gamma delta T-cell lymphoproliferative disorder/lymphoma presenting in the skin that lacked the expected cytotoxic markers and had increased expression of CD5, CD20, CD79a, CD30, and PD-1 without CD56. Monoclonal TCR-γ gene rearrangement was identified. A computed tomography scan of the chest, abdomen, and pelvis revealed a 7.7-cm soft-tissue inguinal mass and prominent retroperitoneal and pelvic lymphadenopathy, without hepatosplenomegaly. Flow cytometry finding on peripheral blood was normal. The clinical, morphologic, and immunophenotypic features of this case defy the current World Health Organization and European Organization for Research and Treatment of Cancer classifications, and a similar case has not been reported previously.

BACKGROUND: There is little existing research investigating SH/SA specifically from patients to students. This study aims to assess the prevalence and impact of SH and SA from patient to medical student. METHODS: A cross-sectional survey study was administered via electronic email list to all current medical students at the University of Washington School of Medicine (n = 1183) over a two-week period in 2019. The survey questions addressed respondents' experiences with SH/SA from patients, frequency of reporting, and impact on feelings of burnout. RESULTS: Three hundred eleven responses were received for a response rate of 26%; 268 complete responses were included in the final analysis. Overall, 56% of respondents reported ever experiencing SH from a patient. SH from a patient was reported by significantly more of those who identify as female compared to male (66% vs 31%; p < .001). Similar frequency of experiencing SH within the last year were reported by females and males (90% vs 88%; p = .96). Clinical students were more likely to have ever experienced SH compared to preclinical students (61% vs 39%; p < .001). The majority (86%) of respondents who experienced SH/SA did not report it in an official capacity. Those who identify as female were more likely to report that SH from a patient contributed to feelings of burnout (21% vs 5% for male; p = .02). Behaviors consistent with SA were experienced by 16% of respondents, with similar frequency between females and males. CONCLUSIONS: This study demonstrates that patient to medical student SH/SA is a common occurrence, particularly among students identifying as female. It also highlights the significant impact of SH/SA incidents on feelings of burnout.

The primary cutaneous CD30+ lymphoproliferative disorders are a family of extranodal lymphoid neoplasms that arise from mature postthymic T cells and localize to the skin. Current classification systems recognize lymphomatoid papulosis (LyP), primary cutaneous anaplastic large cell lymphoma, and borderline cases. In the majority of patients, the prognosis of primary cutaneous CD30+ lymphoproliferative disorders is excellent; however, relapses are common, and complete cures are rare. Skin-directed and systemic therapies are used as monotherapy or in combination to achieve the best disease control and minimize overall toxicity. We discuss 3 distinct presentations of primary cutaneous CD30+ lymphoproliferative disorder and present recommendations for a multidisciplinary team approach to diagnosis, evaluation, and management of these conditions in keeping with existing consensus guidelines.

BACKGROUND: Early and accurate diagnosis of systemic amyloidosis (SA) is critical for optimal patient outcomes. Biopsy of clinically uninvolved skin and subcutaneous tissue including abdominal skin punch biopsy (ASPB) is often used as a surrogate for affected organ sampling. There is a lack of published data on the sensitivity and specificity of ASPB for diagnosing SA. METHODS: Retrospective chart review between 2000 and 2020 of all ASPB was performed to diagnose SA. Amyloid deposition was confirmed by Congo red stain. Study group includes patients with histopathologically and clinically confirmed diagnosis of SA. Control group includes patients without histopathology of amyloid deposition and no clinical SA. RESULTS: Forty-one patients meeting inclusion criteria were analyzed; 23 study group and 18 control group patients. The overall diagnostic sensitivity of ASPB was 43% (95% CI 23%-66%) and the specificity 100% (95% CI 81%-100%). The AL amyloidosis diagnostic sensitivity was 64% (95% CI 35%-87%). ASPB >10 mm in depth had 100% (95% CI 54%-100%) sensitivity compared to 24% for depth ≤10 mm (P = .002). CONCLUSIONS: ASPB is a minimally invasive and highly specific method of diagnosing SA. It is particularly sensitive for diagnosing AL amyloidosis and the diagnostic sensitivity can be significantly improved with adequate biopsy depth and diameter.

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare cutaneous adnexal neoplasm typically arising on the face of older individuals, most commonly around the eyelids. Histopathologic features include a circumscribed proliferation of low-grade epithelioid cells with areas of cystic and cribriform growth, foci of intracytoplasmic and extracellular mucin, and coexpression of endocrine, neuroendocrine, and cytokeratin markers by immunohistochemistry. Given histopathologic and immunohistochemical similarities, EMPSGC is often likened to solid papillary carcinoma of the breast and endocrine ductal carcinoma in situ, and is thought by many to represent a forme fruste of mucinous carcinoma of the skin. To date, the vast majority of reported cases of EMPSGC have been described as having indolent behavior, with no cases of distant metastasis yet reported. Here we report a unique case of EMPSGC that recurred over several years following standard surgical excision and Mohs micrographic surgery, with subsequent metastasis to the parotid gland and axial skeleton.

BACKGROUND: The histopathological diagnosis of MF is challenging, and there is significant overlap with benign inflammatory processes. Clinical features may be relevant in the assessment of skin biopsies. METHODS: We provided photomicrographs to board-certified dermatopathologists and one hematopathologist with and without accompanying clinical photographs and assessed accuracy and confidence in diagnosing MF. RESULTS: We found that access to clinical photographs improved diagnostic accuracy in both MF and non-MF (distractors); the degree of improvement was significantly higher in the non-MF/distractor category. Across all categories, diagnostic confidence level was higher when clinical images were available. CONCLUSION: These findings suggest that clinical images are useful in making an accurate diagnosis of MF, and may be particularly helpful in ruling it out when an inflammatory disorder is clinically suspected.

Pyoderma gangrenosum (PG) lacks consensus regarding treatment, and no prior studies assess treatment satisfaction in PG. The objective of this study was to determine patient-reported satisfaction in the treatment of PG, and associations with satisfaction. Methodology was a multicenter cross-sectional survey for patients who received systemic medication(s) to treat PG. Thirty-five patients completed the survey (mean age: 54.0 years, 65.7% female, response rate: 81.4%). Mean (± SD) SATMED-Q score was 75.0 (±16.2, range: 67.6-85.3). Older patients (72.6 ± 23.6 for 18-39 years, 74.4 ± 16.1 for 40-59, 77.1 ± 11.6 for 60+), plus those with higher incomes (72.9 ± 20.3 for $0-49 000; 74.0 ± 17.6 for $50 000-99 000; 79.0 ± 14.6 for $100 000+) and education status (69.4 ± 14.3 for high school equivalent, 72.9 ± 15.9 for undergraduate, 91.7 ± 10.6 for graduate), were more satisfied with treatment. Ulcerative PG had higher SATMED-Q scores (79.0 ± 13.2) than other subtypes (66.2 ± 19.3). For local therapy, wound care, or pain control, 63.2%, 100%, and 75% were satisfied, respectively. The mean DLQI was 8.6 (±7.6, range: 0-29), and higher DLQI was associated with decreased satisfaction. Satisfaction with providers was positively correlated with global satisfaction (Pearson's r = 0.638). The presence of pain and/or depression influenced both SATMED-Q (72.8 ± 18.8 with pain, 78.3 ± 11.2 without; 68.2 ± 18.8 with depression, 80.1 ± 12.2 without) and DLQI scores (12.1 ± 8.1 with pain, 3.9 ± 3.4 without; 10.3 ± 7.1 with depression, 7.4 ± 8.0 without). To optimize the patient experience, non-modifiable associations should be individually considered, and potentially modifiable associations such as satisfaction with specific providers, pain, and depression, may be targeted for management.

Behçet's disease (BD) is a heterogeneous multi-organ disorder in search of a unified pathophysiological theory and classification. The disease frequently has overlapping features resembling other disease clusters, such as vasculitides, spondyloarthritides and thrombophilias with similar genetic risk variants, namely HLA-B*51, ERAP1, IL-10, IL-23R. Many of the BD manifestations, such as unprovoked recurrent episodes of inflammation and increased expression of IL-1, IL-6 and TNFα, overlap with those of the hereditary monogenic autoinflammatory syndromes, positioning BD at the crossroads between autoimmune and autoinflammatory syndromes. BD-like disease associates with various inborn errors of immunity, including familial Mediterranean fever, conditions related to dysregulated NF-κB activation (eg TNFAIP3, NFKB1, OTULIN, RELA, IKBKG) and either constitutional trisomy 8 or acquired trisomy 8 in myelodysplastic syndromes. We review here the recent advances in the immunopathology of BD, BD-like diseases and the NF-κB pathway suggesting new elements in the elusive BD etiopathogenesis.

Dermatologists treating immune-mediated skin disease must now contend with the uncertainties associated with immunosuppressive use in the context of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Although the risk of infection with many commonly used immunosuppressive agents remains low, direct data evaluating the safety of such agents in coronavirus disease 2019 (COVID-19) are scarce. This article reviews and offers guidance based on currently available safety data and the most recent COVID-19 outcome data in patients with immune-mediated dermatologic disease. The interdisciplinary panel of experts emphasizes a stepwise, shared decision-making approach in the management of immunosuppressive therapy. The goal of this article is to help providers minimize the risk of disease flares while simultaneously minimizing the risk of iatrogenic harm during an evolving pandemic.

Significant communication occurs between pathologists and clinicians through the dermatopathology report. Our objective was to describe clinician preference about reporting of the margin status of skin biopsies of nonmelanoma skin cancers. An anonymous survey was sent to 243 medical providers who submitted specimens to a single institution university medical center; 50 complete responses from attending-level providers and advance practice providers were received. The majority (96%) of those surveyed indicated margins should be reported on skin biopsies of neoplasms, particularly nonmelanoma skin cancers (basal cell carcinoma 96% and squamous cell carcinoma 92%) and atypical nevi (96%). When asked about particular language used to describe the margin status, some phrasing led to more variance in respondents' clinical management decisions, with 96%-98% of respondents making the same decision when presented with "unambiguous" terms and 58%-84% of respondents making the same decision when presented with "ambiguous" language (P < 0.001). Respondents generally preferred "unambiguous" margin descriptions when shown an involved margin (70% vs. 30%, P < 0.001) but accepted "ambiguous" language when the margin was clearly uninvolved (68% vs. 32%, P = 0.015). Most respondents (88%) desire inclusion of treatment recommendations in dermatopathology reports. Microscopic descriptions were highly utilized, particularly by nondermatology trained clinicians (97% vs. 80%, P = 0.09). Clinicians desire inclusion of margins for skin biopsies in dermatopathology reports, at least in some circumstances. The choice of language used to describe the margin status in dermatopathology reports has important implications for patient care. Margin descriptors that are unclear or ambiguous may lead to more variance in clinical management.
