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

Abstract

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.
