RESUMO
Bee stings usually result in mild allergic reactions; however, mass envenomation can cause severe complications such as rhabdomyolysis, hemolysis, shock, or multi-organ damage. Rhabdomyolysis can result in acute renal failure either by tubular obstruction by myoglobin casts or by direct cytotoxic injury. We present a case of a 12-year-old female child who presented with sudden onset anuria and hypertension following mass envenomation by bees. A renal biopsy was performed, the microscopic evaluation of which revealed tubular injury, with associated intratubular pigmented casts. The casts stained positive for myoglobin immunohistochemical stain, thus confirming a diagnosis of myoglobin cast nephropathy. The patient was given IV steroids and underwent seven sessions of hemodialysis, following which there was complete recovery of renal function.
