Abstract

Tsutsugamushi disease, an infectious disease by Rickettsia(R.) tsntsugamushi, is characterized by eschar, fever and rash. Eschar caused by chigger bite, is pre sent on 47 94% of patients with documented R. tsutsugamushi. We recently noticed one case of R. tsutsugamushi infection. Patient had fever, heaclache, lymphadenopathy, erythematous maculopapules and eschar. The R. tsu tsugamushi was isolated from serum of the patient. Histopathologic findings of eschar show epidermal ulceration overlying a zone of coagulative necrosis of upper dermis and necrotizing vasculitis. E]ectron microscopic findings of endothelial cells of capillary show rickettsia with cell division.
