The Bowel-Associated Arthritis–Dermatosis Syndrome (BADAS): A Systematic Review, 2023.
New info on the neutrophilic dermatosis, bowel-associated dermatosis arthritis syndrome, is rarely available. It's normally associated with bowel bypass surgery, but has been associated with other gastroenterological conditions, particularly inflammatory bowel disease. It can cause Sweet's syndrome-like skin lesions. Both Sweet's syndrome and bowel-associated dermatosis arthritis syndrome, are forms of neutrophilic dermatosis (see comments).
"Bowel-associated arthritis–dermatosis syndrome (BADAS) is a rare neutrophilic dermatosis that was first described in 1971 in patients who underwent bypass surgery for obesity. Over the years, the number of reported cases associated with medical gastroenterological conditions, particularly inflammatory bowel disease (IBD), has progressively increased."
"Bariatric surgery and IBD were the most frequently reported causes of BADAS, accounting for 63.7% and 24.7% of all cases, respectively. A total of 85% of cases displayed the typical dermatological presentation, including urticarial maculopapular lesions centered by a vesicopustule, with the majority of lesions located on the upper limbs (73.5%). Polyarthralgia or localized arthritis were always present. Atypical presentations included cellulitis-like, erythema-nodosum-like, Sweet-syndrome-like and pyoderma-gangrenosum-like manifestations. Gastrointestinal symptoms were frequently observed in IBD-related cases (67.9%). The histopathology showed a neutrophilic infiltrate (96.6%). The most commonly used treatment regimens consisted of systemic corticosteroids, metronidazole and tetracyclines, either alone or in combination." ncbi.nlm.nih.gov/pmc/articl...
