Human granulocytic anaplasmosis (HGA) is a tick-borne illness caused by infection with Anaplasma phagocytophilum. Although rare, rhabdomyolysis and acute renal failure are potential complications of HGA. We present the case of an 86-year-old male who exhibited severe myopathy, rhabdomyolysis, and acute renal failure necessitating hemodialysis. Treatment with doxycycline resulted in partial renal function improvement, allowing discontinuation of dialysis after 8 weeks. This case underscores the importance of considering rhabdomyolysis as a manifestation of HGA, particularly in individuals residing in or traveling to endemic areas.
