Sweet’s syndrome: a clinical entity need to discriminate against acute haematogenous periprosthetic joint infection

Abstract

Sweet's syndrome (SS) or acute febrile neutrophilic dermatosis is an uncommon condition. It is characterized by fever, polymorphonuclear leukocytosis, painful erythematous cutaneous plaques, and dense dermal infiltrate of neutrophils without vasculitis at the site of skin lesions. Lesions in SS might enlarge and coalesce with increasing dermal oedema, resulting in pseudo-vesicular appearance mimicking joint infections. Here, a rare case of SS mimicking acute haematogenous periprosthetic infection in a 74-year-old woman with a history of total knee arthroplasty is reported. This report aims to elaborate clinical various manifestations of SS in a patient with a history of total knee arthroplasty. In addition, this report describes how to discriminate inflammation between SS and periprosthetic joint infection. Level of evidence V.

Sweet syndrome following routine orthopedic surgeries: A case series of 7 patients with surgical rechallenges

“… 2 , 3 With regard to surgical procedures, SS has been described in the setting of varicose vein surgery, 4 spinal surgery, 5 pneumonectomy, 6 and coronary artery bypass grafting. 7 SS arising after orthopedic surgeries is rare; reported cases include development of SS 11 years after undergoing bilateral total knee arthroplasty, 8 3 weeks after a right tibial osteotomy, 9 and necrotizing SS 2 days after elective right partial palmar fasciectomy. 10 …”
