Blocking a rash diagnosis: a rare case of infective endocarditis.

We report a case of a previously healthy, afebrile patient who presented with subacute bilateral lower extremity rash and complete heart block, which was later found to be secondary to infective endocarditis. His transoesophageal echocardiogram detected multiple vegetations and blood cultures were positive for , a nutritionally variant streptococcus that is a normal component of oral flora and thought to be responsible for approximately 5% of all cases of streptococcal endocarditis. Due to concerns for renal failure, the patient was treated with an unconventional regimen of ampicillin and ceftriaxone. He underwent a valve replacement and pacemaker placement and has done well since hospital discharge.
