Very Early-Onset Inflammatory Bowel Disease (VEO-IBD) Presenting with Recurrent Leukocytoclastic Vasculitis Preceded by Streptococcal Pharyngitis.

Case Rep Pediatr 2021 20;2021:1996430. Epub 2021 May 20.

Department of Pediatric Gastroenterology, Hepatology, and Nutrition, Nicklaus Children's Hospital, Miami, FL, USA.

Inflammatory bowel disease (IBD) that presents in children <6 years of age is known as very early-onset IBD (VEO-IBD). Extraintestinal manifestations in IBD, such as erythema nodosum (EN), pyoderma gangrenosum (PG), and, less likely, leukocytoclastic vasculitis (LV), are more commonly present in Crohn's disease. Association between LV and ulcerative colitis (UC) is not commonly seen. Read More

Abstract: Leukocytoclastic vasculitis (LCV) is a small vessel inflammatory condition considered to be caused by circulating immune complexes and often occurs after an acute infection or exposure to a new medication, although it may be associated with an underlying systemic disease or be idiopathic in nature. It is important to determine the etiology, identify the extent of the disease for early intervention and appropriate management, and treat and/or eliminate the underlying cause. Here, we report cases of scurvy and tinea corporis that presented with histopathologic features of LCV and had significant clinical improvement with treatment of the underlying etiologies. Read More

Leukocytoclastic Vasculitis and Microvascular Occlusion: Key Concepts for the Working Pathologist.

Surg Pathol Clin 2021 Jun 28;14(2):309-325. Epub 2021 Apr 28.

Department of Dermatology, Yale University, 333 Cedar Street, PO Box 208059, New Haven, CT 06520, USA; Department of Pathology, Yale University, 310 Cedar St, New Haven, CT 06511, USA.

Although clinicians often put vasculitis and microvascular occlusion in the same differential diagnosis, biopsy findings often are either vasculitis or occlusion. However, both vasculitis and occlusion are present in some cases of levamisole-associated vasculopathy and certain infections. Depth of dermal involvement and vessel size should be reported, because superficial and deep small vessel leukocytoclastic vasculitis and/or involvement of medium-sized vessels may be associated with systemic disease.

Acute Hemorrhagic Infancy of Edema: A Purpuric Rash in 6-Month-Old Infant.

J Investig Med High Impact Case Rep 2021 Jan-Dec;9:23247096211017413

Emory University, Atlanta, GA, USA.

Acute hemorrhagic edema of infancy (AHEI) is a cutaneous leukocytoclastic vasculitis presenting with purpura, ecchymosis, fever, and edema. Pediatricians must effectively differentiate AHEI from other diseases that have similar presentations but are more severe in order to treat appropriately without overutilizing expensive, unnecessary diagnostic tests. In this article, we describe a case of a 6-month-old previously well male who presented to our institution with a worsening rash and fever. Read More

A novel histopathological scoring system to distinguish urticarial vasculitis from chronic spontaneous urticaria.

Clin Transl Allergy 2021 Apr;11(2):e12031

Dermatological Allergology, Allergie-Centrum-Charité, Department of Dermatology and Allergy, Charité - Universitätsmedizin Berlin, Berlin, Germany.

Background: Urticarial vasculitis (UV) is defined by long-lasting urticarial lesions combined with the histopathologic findings of leukocytoclastic vasculitis. As one of the major unmet needs in UV, diagnostic criteria are rather vague and not standardized. Moreover, there seems to be considerable overlap with chronic spontaneous urticaria (CSU), particularly for the normocomplementemic variant of UV. Read More

Palisaded Neutrophilic and Granulomatous Dermatitis in a Patient with Behçet's Disease: A Case Report.

Ann Dermatol 2021 Feb 30;33(1):73-76. Epub 2020 Dec 30.

Department of Dermatology, Gyeongsang National University School of Medicine, Jinju, Korea.

PNGD is known to be associated with various immune-mediated connective tissue diseases such as rheumatoid arthritis and lupus erythematosus. However, to our knowledge, a case of PNGD in a patient with Behçet's disease is extremely rare and only one case has been reported in foreign literature to date. Read More

Acta Derm Venereol 2021 May 4;101(5):adv00449. Epub 2021 May 4.

Skin and Endothelium Research Division (SERD), Department of Dermatology, Medical University of Vienna, AT-1090 Vienna, Austria.

The aim of this study was to develop vascular histomorphological diagnostic criteria differentiating Martorell ulcers from other types of leg ulcers. The histomorphology of patients diagnosed with arteriolosclerotic ulcers of Martorell (n = 67) was compared with that of patients with venous leg ulcers, necrotizing leukocytoclastic vasculitis, pyoderma gangrenosum, and non-ulcerative controls (n = 15 each).
