The patient presented local erythema, edema, increased local temperature and blister with serous fluid in the right arm. He developed acute kidney injury (AKI) and prolonged thrombocytopenia. The blood was incoagulable and he was treated with anti-bothropic antivenom and antibiotics. The patient had complete regression of all clinical and laboratory manifestations at varying intervals.
