Urinary Canthariasis Due to Tenebrio molitor Larva in a Ten-Year-Old Boy

Canthariasis is a human disease caused by infestation of beetle larvae. We report here an unusual cause of urogenital in fection due to Tenebrio molitor in a 10-year-old boy suffering from severe and intermittent suprapubic pain from Nehban dan City, Northeastern Iran in 2018. After 9 months, three larvae were excreted. Keratinization of bladder wall was ob served in histopathology. All laboratory evaluations were normal except for presence of microscopic hematuria. This re port implicated that T. molitor could infest bladder accidentally and cause canthariasis and clinical symptoms that may lead to severe pain and bladder inflammation and hyperemia.
