Mycosis fongoïde transformé chez un enfant : traitement par transplantation médullaire allogénique avec effet « graft-versus-lymphoma »

This is a new case report of juvenile mycosis fungoides with unusual clinical features such as rapid course and transformed form at presentation. Juvenile mycosis fungoides represents 2.5 to 5% of cases of mycosis fungoides and transformation to large cell lymphoma is exceptional. Our case illustrates the aggressive pattern observed in some teenage patients as well as the efficacy of bone marrow allograft, most likely thanks chiefly to its graft-versus-lymphoma effect.
