A man developed compartment syndrome requiring fasciotomy after likely acquiring haemophilia A from an asymptomatic SARS-CoV-2 infection, US doctors report.

The 65-year-old presented to hospital with acute shortness of breath, chest pain, and a one-week history of atraumatic painful bruising underneath the skin.

He denied prior respiratory infection, but his medical history was significant for congestive heart failure, sick sinus syndrome with a permanent pacemaker, COPD and Hashimoto’s syndrome managed with thyroidectomy and levothyroxine for 30 years.

Physical examination revealed a large, tense ecchymotic/purpuric plaque on the right upper arm with similar plaques on the forearm, an oedematous right hand, paraesthesias and diminished sensation of the fingers of the right hand.
