Patient 1:<\/h1>\n

This is a previously healthy young woman who\u00a0presented with subacute atraumatic pain and swelling of her right knee and left foot. The right knee was erythematous and warm with an associated joint effusion that contained 15K WBC\/\u03bcL but no organisms or crystals. She was taken for a washout of the knee for presumed septic arthritis. Later, physical examination revealed\u00a0<\/span>well-demarcated erythematous plaques involving the posterior neck and ear, as well as the oil drop sign on one of her fingernails, consistent with psoriatic arthritis.<\/span><\/p>\n
