[Mycosis fungoides--the practionner confronted with the nosological, diagnostic and prognostic problems of epidermotrophic lymphomas (author's transl)].

The authors have studied 39 cases of mycosis fungoides in the last 3 years. The confrontation between clinical and histological data remains the best means of diagnosis and prognosis. The classical classification into three clinical forms must be maintained; laboratory investigations do not yet supply practical information for prognosis and therapy. At present, the prognosis cannot be established otherwise than on clinical grounds; a pragmatic staging method is needed.
