A rare case of scrub typhus vasculitis presenting as acute coronary syndrome diagnosed by skin manifestations.

A 48-year-old diabetic man presented with complaints of acute onset chest heaviness with palpitations, anxiety and headache. He had raised troponin-T level and electrocardiogram showed ST elevation myocardial infarction. There was a prior history of fever of 4 days duration with associated abdominal pain. He later developed skin rash and neurological symptoms following admission to the hospital. Dermatological examination revealed purpura and a livedo-like rash. Investigations revealed deranged liver and renal function tests and positive serological tests for scrub typhus. Coronary angiography revealed no evidence of atherosclerosis or any other pathology. He was therefore diagnosed as a case of scrub typhus-induced vasculitis with coronary manifestations and was managed with oral doxycycline. Scrub typhus presenting like an acute coronary syndrome has been reported very rarely previously. In addition, patient had gastrointestinal, central nervous system and hematological involvement which added to the rarity of the case.
