Allergic contact dermatitis from stomadhesive paste

Abstract

A woman developed dermatitis from Stomadhesive paste used to secure her colostomy appliance. Patch testing revealed that she was allergic to Gantrez (N-butylmonoester of polymethyl vinyl ether maleic acid in an ethanol solution), a water soluble copolymer with stabilizing properties used in the production of Stomadhesive.

The spectrum of skin disorders in abdominal stoma patients

“…The medical literature instead consists of isolated case reports of unusual peristomal dermatoses 6–11 or specific contact allergic hypersensitivities. 12–19 …”

Results of patch testing in 10 patients with peristomal dermatitis

“…Previous reports of ACD to Stomahesive paste (ConvaTec Inc) identified the causative allergen as Gantrez (polymethylvinylether), which is a polymer component in adhesives. 15,20,23,24 One other case of ACD caused by Stomahesive paste (ConvaTec Inc) was negative to Gantrez, but the causative allergen remained unknown because the manufacturer refused to supply other components for additional testing. 22 Our 10 patients did not undergo further testing to individual materials in their stoma device and supplies.…”

Peristomal allergic contact dermatitis – case report and review of the literature

“…Contact allergy to Gantrez ® causing peristomal dermatitis has been previously reported in only 2 patients (2, 3). In both cases, this was through the use of Stomahesive ® paste.…”

“…There have only been 23 cases of ACD causing stoma‐related dermatitis previously reported in the literature (2–15). Various aspects of stoma care can cause exposure to potential allergens including the stoma bag itself (9 cases), seal rings (3 cases), strapping (1 case), adhesive devices (3 cases), adhesive removers (2 cases) and deodorants (2 cases).…”
