A case report reveals schistosomiasis causing bladder mass in an adolescent, indicating need for awareness of its symptoms.
We report the case of a 16-year-old adolescent from Mali who was admitted for acute macroscopic hematuria. CT urography revealed bladder wall calcifications associated with an endoluminal lesion, and cystoscopy identified a 16-mm polyp. Schistosomal serology was equivocal, while urine parasitology demonstrated nonviable eggs compatible with Schistosoma haematobium. A complete transurethral resection was performed, and histopathological examination revealed calcified eggs within the lamina propria without any signs of malignancy. This case highlights the importance of considering schistosomiasis in the differential diagnosis of hematuria associated with a bladder mass in children and of inquiring about prior residence in endemic areas.
