Cutaneous manifestations of hematologic malignancy represent both a clinical challenge for the treating physician and pathophysiological model advancing knowledge on individual neoplasms. Indeed, growing body evidence supports concept recurrent molecular defects associating with specific features, as best exemplified by VEXAS. Herein neutrophilic eosinophilic dermatoses potential interest hematologists dermatologists will be reviewed, including subcorneal pustular dermatosis-type IgA pemphigus, eccrine hidradenitis, Sweet’s syndrome well myelodysplasia cutis VEXAS, pyoderma gangrenosum, annular erythema, dermatosis hematological malignancy, Wells cutaneous involvement in hypereosinophilic syndromes. Possible management approaches are discussed each, emphasizing scenarios that require treatment underlying condition to achieve remission at skin level.

Atopy in chronic urticaria: an important yet overlooked issue

Frontiers in Immunology, Journal Year: 2024, Volume and Issue: 15

Chronic urticaria (CU) is one of the most common dermatological diseases and has a significant impact on quality life patients. However, pathogenesis this disease remains unclear. Autoimmunity in chronic spontaneous (CSU) received considerable attention been studied previously. Atopy an important characteristic CU; however, it not fully recognized. predisposes individuals to immune responses allergens, leading type 2 inflammation immunoglobulin E (IgE) overproduction. Compared with healthy individuals, patients CU have higher proportion atopy, atopic background correlated clinical characteristics CU. The total IgE levels significantly than those individuals. Although its level that classic allergic diseases, closely related Exogenous auto-allergens, specific IgEs, which are reported, their roles also being studied. Local systemic present This review summarizes current knowledge regarding atopy CU, speculating there subtypes, such as CSU or inducible (CIndU) may be involved These findings provide new perspective for comprehensive understanding features further research pathogenesis.

Cutaneous vasculitis and vasculopathy in the era of COVID-19 pandemic

Frontiers in Medicine, Journal Year: 2022, Volume and Issue: 9

Published: Aug. 23, 2022

Cutaneous vasculitides encompass a heterogeneous group of clinicopathological entities, which may occur as single-organ vasculitis the skin or present skin-limited variant systemic (i.e., ANCA-associated vasculitis), and are triggered by various factors, including infections, drugs vaccines. The COVID-19 pandemic has challenged us with variety both disease- vaccine-associated manifestations, vasculitis. Among latter, cutaneous small-vessel vasculitis, previously known leukocytoclastic seems to be most reported in either scenario, i.e., natural infection vaccination. Vasculopathy without true vasculitic changes on histology develops but minority cases, mostly severe/critical patients, appears result endothelial injury due pauci-immune thromboembolic mechanisms. Herein, we provide an overview available literature COVID-19-associated anti-SARS-CoV-2-vaccine-associated Although evidence is limited isolated reports, proportion cases lacking histopathological confirmation, ample overlap pre-pandemic forms shown.

A Rare Case of Photo‐Induced Urticarial Vasculitis

Histopathologic Features in Urticaria and Urticarial Variants: Plasma Cells Should Be Rare

Journal of Cutaneous Pathology, Journal Year: 2025, Volume and Issue: unknown

Published: April 22, 2025

ABSTRACT Introduction Urticaria is a common cutaneous reaction pattern characterized by clinically transient edematous papules and wheals. Microscopically, intensity predominant inflammatory cell type can vary, including lymphocytes, eosinophils, neutrophils, mast cells. Plasma cells are rarely described within the infiltrate of urticaria, but systematic study to evaluate frequency this finding lacking. Materials Methods The institutional dermatopathology archive was searched for 2018–2023 identify cases diagnosed as urticaria urticarial variants; 58 consecutive were included. Study authors, one board‐certified dermatopathologist, evaluated H&E slides variation in present, inflammation density/distribution, types. Results Fifty‐eight (female: 39, male: 19) reviewed. Eleven (19%) showed rare, scattered plasma (0.02–0.09/mm 2 ). Other types predominated and, like other studies, fell into lymphocytic neutrophilic categories. Inflammation density predominantly ranged from sparse moderate, with only two having brisk inflammation. Conclusion This highlights that rare may be present biopsies should not abundant or clustered.

Urticaria and other mimickers of urticaria

Frontiers in Allergy, Journal Year: 2025, Volume and Issue: 5

Published: Feb. 13, 2025

Urticaria is a mast cell-dependent skin disease characterized by the presence of hives, angioedema, or both in absence systemic symptoms. It may be acute, chronic. (1) Acute urticaria (AU) common children, affecting boys and girls equally. Chronic (CU) affects adult women more (3). AU than 20% population CU 0.1 1.5%. There are many pathologies that do not meet clinical criteria for urticaria, despite being called urticarias, which leads to erroneous diagnoses inconclusive epidemiology. This review attempts clarify when we should consider as such what can considered without so.
