Lethal anaplastic large-cell lymphoma occurring in a patient treated with dupilumab

The occurrence or the worsening of cutaneous T-cell lymphoma (CTCL) during or after a treatment with dupilumab has recently been reported in a limited number of patients including a small series of 7 patients, of whom 4 had been previously diagnosed with atopic dermatitis (AD).1 We hereby describe a previously unreported observation of systemic CD30+ lymphoproliferation occurring during treatment with dupilumab, adding to the literature of new-onset cutaneous lymphomas associated with dupilumab therapy.
