A Man With Recurrent Fever, Episodic Rash, and Pain

The patient presented to our clinic from out of state in October 2018. Previously, in 2014, he underwent an elective left total hip arthroplasty with a ceramic-on-polyethylene prosthesis for osteoarthritis. The surgery and recovery were uneventful. In November 2014, hives developed on his upper arms. Within weeks, the hives spread to his trunk and thighs but spared his face, palms, and soles. The symmetric, nonpruritic, nonpainful rash was without angioedema. The hives initially persisted for 5 days, followed by resolution for several days.
