Abstract
Skin lesions, if any, are very instrumental in making the diagnosis of subacute bacterial endocarditis (SBE). The best known manifestation is Osler’s node. In this paper we reported two cases of SBE. Case 1: The patient was a 50 year-old man who complained of fatigue, fever, painful reddish nodule (Osler’s node) and erythematous patches (Janeway spots) on fingers. The histopathologic features of biopsied Osler’s node showed slight leukocytoclastic vasculitis in capillaries and small vessels within the dermis. Gram-positive microorganisms were found around a vessel wall. Case 2: The patient was a 38 year-old man having complained of fever, polyarthralgias and small purpuric spots on the hand, fingers and conjunctiva. The blood culture was positive for Streptococcus viridans.
