Objective: Hematuria is defined as the presence of red blood cells in urine, which may be observed microscopically or grossly. Hematuria may originate from any site throughout the urinary tract, glomerulus, interstitium, or the renal vasculature. Here, we present the case of a 17-year-old boy who developed terminal hematuria after two months of treatment with isotretinoin for acne vulgaris. Radiological and cystoscopic assessment of the urinary system were normal. Isotretinoin treatment was discontinued after dermatology consultation. After two weeks, terminal hematuria disappeared along with dysuria, and the urine sample showed normal findings.
Keywords: Acne vulgaris, adverse effect, gross hematuria, isotretinoin
