Case Report
A thirty-eight year-old male presented to the outpatient primary care clinic with a seven-week history of fever unresponsive to oral antipyretics. The patient also noted recurrent chills, night sweats, myalgias, headaches, and chest tightness. Three days before presentation, he developed a cough with clear sputum. A complete review of systems was otherwise negative. A careful history emphasizing surgical, social, and travel components revealed that the patient had undergone arthroscopic ACL reconstruction seven weeks prior to presentation, after which his fever began. He tested negative for COVID-19 pre-operatively. On surgical follow-up, his orthopedist found no surgical or thromboembolic complications or other iatrogenic cause for fever. Approximately one week after initial presentation, the patient developed an erythematous maculopapular rash on the palmar surfaces of both hands (Figure 1 ). Arthralgias, myalgias, and morning stiffness worsened, and the rash spread over his torso.
