Abstract

Cases:Two elderly women each presented with a unilateral, erythematous rash 1 year after total knee arthroplasty (TKA) for osteoarthritis. Both cases were diagnosed as postsurgical nummular eczema (NE) and treated successfully with topical corticosteroids.Conclusion:We highlight a novel clinical presentation of postsurgical NE associated with TKA, previously reported only with breast reconstruction. Postsurgical NE may mimic periprosthetic infection or implant-related allergic contact dermatitis. Timely diagnosis and appropriate treatment in these cases prevented unnecessary testing and hospital admission for revision surgery. This case series highlights the varied presentation and wide differential diagnosis associated with postsurgical NE.
