{Abstract}: A woman in her late 40s with a history of psoriatic arthritis presented to us with fever, migratory rash, cervical and axillary lymphadenopathy, and generalised myalgia. Her symptoms did not improve with steroids and her inflammatory markers were in the range of 200 mg/dL for C-reactive protein, erythrocyte sedimentation rate of 71 mm/hour and ferritin of 4000 ng/mL. Infectious workup was negative. Haematological malignancy and autoimmune conditions were among the top differentials, and she was eventually diagnosed with Schnitzler syndrome. A multidisciplinary team consisting of internal medicine, rheumatology, infectious disease and haematology-oncology specialists was involved in the care of this patient. We highlight the diagnostic schema that was followed for this rare and unique constellation of symptoms.
