Sweet syndrome (SS) is an uncommon auto-inflammatory disorder presenting with acute pyrexia, leucocytosis and erythematous skin lesions with dense neutrophilic dermal infiltration. SS is seen as adverse reaction to some drugs, microbes and is associated with certain myeloproliferative or haematological neoplasms and is also seen with autoimmune diseases like inflammatory bowel disease, systemic lupus erythematosus, rheumatoid arthritis, etc. A female aged 43 years, came to the hospital with high fever and erythematous, pus-filled plaques and nodules on her face, neck, shoulders and extremities, after taking cotrimoxazole (antibacterial agent) in tablet form 480 mg twice daily for five days for urinary tract infection. The diagnosis of SS was arrived upon from the biopsy reports showing predominant neutrophilic infiltrate, and relevant laboratory tests. Treatment included oral prednisone (corticosteroid) and the symptoms resolved in two months.
