CME Credits: 1.00

Released: 2021-12-16

A 51-year-old woman presented with a 1-month history of intense and worsening polyarthralgia and swelling of bilateral fingers and toes. There was no history of alopecia, oral ulcers, rashes, or Raynaud phenomenon. She did not report preceding fever, diarrhea, or dysuria. There was no history of weight loss or anorexia. Medical history included tertiary hyperparathyroidism related to end-stage kidney disease from chronic glomerulonephritis. The patient had successfully received an ABO-incompatible kidney transplant 1 year ago, but this was complicated by invasive fungal (Volvariella volvacea) infection of the central nervous system. Medications included tacrolimus (0.5 mg twice daily), prednisolone (10 mg daily), cinacalcet (12.5 mg daily), and voriconazole (500 mg daily). On examination, her fingers and toes were symmetrically and diffusely swollen and tender. There was no rash, enthesitis, psoriatic nail changes, clubbing, or lower limb edema. The rest of the physical examination was unremarkable.
