Inviting InnovationsWhile the etiology of MF remains unknown, various hypotheses have been proposed which include genetic, environmental, infectious, and autoimmune involvement [4,5]. Recently, there have been several reports of MF diagnosed after the initiation of dupilumab therapy for atopic dermatitis (AD) or other eczematous conditions [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. In this report, we present another case of AD developing stage IIB MF in the ensuing months after starting dupilumab and a systematic review of all published cases of this association, as well as the hypotheses for how this transition may occur.
MethodsA systematic English language literature review using PubMed and Google Scholar between January 2021 and March 2023, with key words of (mycosis fungoides and dupilumab, cutaneous T cell lymphoma and dupilumab, as well as descriptors of transformation, progression and misdiagnosis) was conducted to identify reports of the diagnosis of MF/CTCL in association with dupilumab treatment.
