Abstract:
Tsutsugamushi disease is caused by the bacterium, Orientia tsutsugamushi and transmitted by chigger mites. In addition to the typical dark eschar, various forms of the eschar, including papules and vesicles, develop at chigger bite sites. Macular lesions were reported only in a human inoculation study; the inoculation lesions relapsed as erythematous macules or erythema-based papules concomitant with fever relapse. Herein, we report an erythematous patch as an inoculation lesion in two patients with tsutsugamushi disease, which, additionally, displayed a central small circle of 1 mm in diameter, possibly a chigger bite site, and desquamation around the circle during doxycycline therapy.
