Cutaneous, purpuric painful nodules upon addition of ibrutinib to RCVP therapy in a CLL patient: A distinctive reaction pattern reflecting iatrogenic Th2 to Th1 milieu reversal
Background. Eosinophilic dermatosis of hematologic disorders is a reactive process that may cause a variety of clinical manifestations. Methods. We report a patient who had outbreaks of skin lesions since the onset of chronic lymphocytic leukaemia. Results. The cutaneous eruptions began as eosinophilic panniculitis and after changed to insect bite-like lesions. Conclusion. We think that eosinophilic panniculitis and insect bite-like lesions may be part of the spectrum of the same entity in patients with hematologic disorders.
