Remissions of mycosis fungoides induced by nitrogen mustard (HN2). Topical treatment and hydration of tumours and plaques with HN2. Topical desensitization to HN2. A clinical and histopathological controlled study.

In this study 12 patients with mycosis fungoides were treated with whole body topical application of HN2. In addition 4 of these patients had gauzes moistened with the same HN2 solution placed upon plaques and tumours. 4 patients developed in allergic contact dermatitis, and this complication was overcome by percutaneous desensitizing in 3 of them. After starting hydration of plaques and tumours with HN2, the average time to obtain complete clinical remission was shorted from 4.4 to 2.5 months. A little later at the optimal histologic response, there was no or almost no cellular infiltration in 5 cases, while in 6 cases there was only a slight, unspecific, lymphocytic infiltrate in the dermis.
