Invasive Urothelial Carcinoma of the Urinary Bladder in a 19-Year Old Boy with Urinary Schistosomiasis: A Case Report and Review of Literature

Abstract

Background: Invasive urothelial carcinoma of the bladder is a malignant urothelial tumor seen mainly in the 6th and 7th decade of life, and extremely rare in the 1st and 2nd decade. The major predisposing factors include exposure to environmental carcinogens such as aniline dyes, rubber, cigarette smoking, and chronic irritation such as those from long standing bladder stones and indwelling urethral catheters. Only a few cases resulting from Schistosoma haematobium-induced chronic inflammation have been reported. Here we report a 19-year old boy who presented to our facility with 3month history of recurrent, terminal, painless hematuria and lower dull aching abdominal pain with Schistosoma ova on urine microscopy and biopsy confirmed an invasive urothelial carcinoma.
