title: Topical vitamin D3 derivatives in treating hyperkeratotic palmoplantar eczema: a report of five patients.
abstract: The treatment of hyperkeratotic palmoplantar eczema is notoriously difficult. A considerable number of patients do not or only partially respond to the current treatments such as topical corticosteroids, topical keratolytics, or PUVA therapy. The purpose of this pilot study was to look for an alternative treatment for hyperkeratotic palmoplantar eczema. We treated five patients with topical vitamin D3 derivatives (calcipotriol 50 microg/g and maxacalcitol 25 microg/g ointments). The lesions almost disappeared after 2 to 8 weeks of treatment in four patients and extremely improved with a seven week treatment in one patient. No adverse effect was observed during or after the treatment, and routine laboratory investigations were within normal ranges. When relapses occurred, they responded well to retreatment. Although the study is preliminary, the results suggest that vitamin D3 derivatives offer a safe, effective alternative form of treatment for recalcitrant hyperkeratotic palmoplantar eczema.
