Abstract
AbstractBackgroundMany people live with ostomies after life‐saving surgery. Ostomy patients often suffer from peristomal dermatitis. Allergic contact dermatitis (ACD) has been reported, mostly due to contact allergy (CA) to topical agents.ObjectivesWe present three patients with therapy resistant peristomal dermatitis, suggesting ACD caused by different stoma products.MethodsPatch testing was performed with baseline series, additional series, and selected allergens. They were also tested with their own ostomy products as is and separate extracts of the products. Extracts were analysed using Gas Chromatography–Mass Spectrometry (GC–MS).ResultsIn all three patients we diagnosed CA to 1,6‐hexanediol diacrylate (HDDA), +++ in case (C) 1 and 3, ++ in C 2. HDDA was detected in C 2's ostomy pouch adhesive and in C 1's and 3's flange extenders used to improve the adhesion of the ostomy pouches.ConclusionTherapy resistant peristomal dermatitis should always be suspected of ACD and patch testing, especially with the patient's own products, should be performed.
