In this case series, we investigated the provocative effect of anti-TNFα drugs in the development of cutaneous mycosis fungoides (MF)-like lymphoproliferative reactions. We describe five patients aged between 25–63 diagnosed with autoimmune disorders (psoriatic arthritis–one patient, Crohn’s disease–one patient and ankylosing spondylitis–three patients) who received anti-TNFα agents before the development of a cutaneous lymphoproliferative reaction. Histological and immunophenotypical analysis was typical for mycosis fungoides in all of them. Anti-TNFα agents were stopped with regression of the skin rash. A direct effect of anti-TNFα agents in the development of lymphoproliferative reactions (including MF) is suggested and further analyzed. Treatment cessation can be therapeutic. © 2019, © 2019 Taylor & Francis Group, LLC." }
