Keratoderma climactericum (Haxthausen's disease): clinical signs, laboratory findings and etretinate treatment in 10 patients

10 cases of keratoderma climactericum are reported. This keratosis of the palms and soles appears late in women of menopausal age. The keratotic lesions first develop at the plantar pressure points, making walking troublesome. Involvement of the hands remains discrete. Examination for contact allergy, fungal tests, vitamin A serum levels, and sex hormones were negative or normal in all the 10 patients. Microscopy revealed a lichenified eczema with evidence of mechanical irritation. Etretinate (0.78 mg/kg/day) brought about partial or total remission of the hyperkeratosis. Pain on walking disappeared in all the patients.
