Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, is a rare painful skin condition that is characterized by hyperpyrexia, peripheral blood and skin neutrophilia, and edematous skin lesions. Necrotizing SS (NSS) is a severe and locally aggressive condition that histopathologically resembles a necrotizing soft tissue infection. As opposed to necrotizing soft tissue infections, NSS responds to systemic steroids. SS is divided into three subtypes: classical SS, malignancy-associated SS, and drug-induced SS. Within the malignancy-associated SS subtype, both solid tumor and hematologic malignancies have been precursors to developing SS. Here, we present a case of acute myeloid leukemia-associated NSS.
