[Local treatment of mycosis fungoides with dichlorodiethyl sulfide in combination with phototherapy].

9 patients suffering from mycosis fungoides in various stages were topically treated with dichlorodiethyl sulfide solution associated with photochemotherapy. Topical application of dichlorodiethyl sulfide is indicated in the stages 1 to 3. In more advanced stages, the cutaneous lesions showed good response to therapy, but systemic lesions could not be influenced. Only one patient developed sensitization to topical dichlorodiethyl sulfide. The low incidence of allergic complications may be due to the combined therapy of dichlorodiethyl sulfide and photochemotherapy.
