A 45 year-old gentleman who was to the hospital five weeks with acute bacterial endocarditis. After an appropriate antibiotic regimen was started and he became stable, he was transferred to six-week course of IV antibiotics. On week 5, the patient developed a rash on his lower extremities which were palpable hemorrhagic papules coalescing into plaques, bilateral and symmetric on lower extremities. The most likely diagnosis is :-
- Leukocytoclastic vasculitis secondary to antibiotics
- Septic emboli with hemorrhage
- Urticarial vasculitis
- DIC secondary to sepsis
View Explanation
Most likely cause of skin findings.

Septic emboli with hemorrhage : these lesions tend to occur on the distal extremities
Urticarial vasculitis : presents with a different morphology, which is more nodular and less diffuse
DIC secondary to sepsis : in DIC, coagulation studies are abnormal
