Sweet's Syndrome as a Prodromal Manifestation of Acute Myeloid Leukemia

Sweet's syndrome is a rare dermatological condition characterized by a constellation of clinical features, including fever, neutrophilic leukocytosis, painful skin plaques, and dermal neutrophil infiltration. Various etiologies have been documented, encompassing both underlying diseases and pharmacological agents. We present a case involving a 35-year-old female patient who exhibited fever and progressive cutaneous lesions manifesting as a painful erythematous rash on the limbs and trunk. Initially misdiagnosed as seronegative lupus erythematosus, her condition did not improve. A skin biopsy revealed significant neutrophilic infiltration, and she subsequently developed leukocytosis, leading to a diagnosis of acute leukemia upon bone marrow examination. The patient was treated with chemotherapy, resulting in a relative improvement of her skin lesions.
