A 60 year old man with diabetes complicated by dialysis-dependent renal failure, mitral valve prolapse, benign prostatic hyperplasia, and dyslipidemia presents with fever, chills, night sweats, and a rash. Unfortunately, he can't give a really good history.
His temperature is 38.5 C, his blood pressure is 125/80, his pulse is 85, and his respiratory rate is 16. Physical exam findings are shown above. The second image shows painful nodules. The third image shows painless macules. Two separate blood cultures are positive, but the lab has not been able to determine the organism yet.
Challenge: What are the likely organisms?
1. What does each image show?
2. What's the diagnosis?
All three images shown under Fair Use.
