Haematuria in association with Lynch syndrome.
A 40-year-old Caucasian male presented to the Emergency Department complaining of intermittent painless frank haematuria. Past medical history was significant for Hereditary Non-Polyposis Colon Cancer (HNPCC) and a prophylactic total colectomy. Computed tomography urogram showed thickening in the posterior wall of the bladder. Cystoscopy showed a small bladder mass. Histology showed a papillary urothelial neoplasm of low malignant potential. HNPCC, also known as Lynch Syndrome, is an autosomal dominant disorder responsible for 3-5% of colorectal cancers. There are certain cancers known to be associated with HNPCC; colorectal cancer, endometrial, ovarian, stomach, pancreas, biliary tract, small bowel, brain, renal pelvic and ureteric tumours, sebaceous gland adenomas and keratocanthomas. An association with bladder tumours is not well established.
