A rare concurrence: bee venom associated acute tubular necrosis and acute interstitial nephritis.

Acute kidney injury (AKI) is generally associated with increased morbidity and mortality and is even more devastating in patients with comorbidities. Although AKI due to multiple bee stings is well established in the literature, it is still a rare entity with complex pathophysiologic mechanisms. The most commonly reported histological findings in AKI due to bee stings is acute tubular necrosis (ATN), with a few studies attributing it to acute interstitial nephritis (AIN), whereas the concurrence of both ATN and AIN is rarely reported. We hereby present a 50-year-old known Type 2 diabetes mellitus patient with a prior normal renal function, who developed AKI following multiple stings from >1000 bees. He had a kidney biopsy on account of non-recovery of his kidney function despite being on intermittent hemodialysis that showed combined features of ATN and AIN. He subsequently had a full recovery of his renal function following appropriate management.
