Palmoplantar dermatitis may be due to phenol‐formaldehyde resin contact dermatitis

Both mercaptobenzothiazole (MBT) and p-tert-butylphenol-formaldehyde resin (PTBP) cause shoe dermatitis (1). Concurrent hand dermatitis occurs in MBT allergy and hand dermatitis may present secondarily to a primary contact dermatitis of the feet (2). Occupational hand dermatitis from phenol-formaldehyde resins is recognized (3). Palmo-plantar dermatitis from phenolformaldehyde resins could present in a similar frashion to MBT allergy. We assessed 7 consecutive cases of foot dermatitis from phenol-formaldehyde resins to see if hand dermatitis was also a presenting feature.
