Frictional hyperkeratotic hand dermatitis (FHHD) is an unusual form of chronic eczema relating to repeated frictional trauma. This form of hand eczema is often occupationally related and recalcitrant to therapy. We describe the case of FHHD in a 48-year-old dermatologic surgeon. The eruption was resistant to all topical and protective modalities, but responded completely to 6 sessions of Grenz ray treatment. No recurrence has been noted for over 4 years since completion of therapy. We suggest that Grenz ray treatment is a safe and effective option in treating this form of chronic hand dermatitis.
