Recurrent Sweet's syndrome in a patient with multiple myelom
The present case has been reported in the Journal of Clinical Case Reports. A 34‐year‐old woman was referred to the Hematology with an IgA kappa multiple myeloma (MM). She was diagnosed after the presentation to a dermatologist for a febrile rash with erythematoviolaceous nodules on hands, forearms, and trunk.

Bone marrow (BM) aspirate revealed 50% infiltration by mature plasma cells. A skin‐lesion biopsy confirmed the diagnosis of malignancy‐associated Sweet's syndrome, according to the criteria proposed by Walker and Cohen's.

The patient was started on PAD (bortezomib, doxorubicin, and dexamethasone) chemotherapy. Considering immunosuppression, due to MM and the concomitant treatment with dexamethasone, she was given colchicine (1.5 g/die) for the treatment of the Sweet's syndrome. The lesions disappeared after 10 days, and she continued the MM therapy.
