Corticosteroid-resistant Sweet’s syndrome as the first manifestation of myelodysplastic/ myeloproliferative neoplasm-unclassifiable: a case report

Abstract

A middle-aged man was diagnosed with myelodysplastic/myeloproliferative neoplasm-unclassifiable (MDS/MPN-U), with severe and extensive corticosteroid-resistant Sweet’s syndrome (SS) as the first manifestation, with evidence of clinical manifestations, pathological description, and laboratory evaluation. The skin lesions continued to spread despite treatment with systemic corticosteroids but were successfully treated with intravenous immunoglobulin (IVIG).
