“…10 While the presence of mucous may suggest intestinal-type villous adenoma, this can also be found in association with pseudomyxoma peritonei, xanthogranulomatous pyelonephritis and local invasion from gastrointestinal malignancy. 6,11 Therefore, definitive diagnosis relies on light microscopy.…”

E138Intestinal type villous adenoma of the renal pelvis AbstractIntestinal type villous adenomas are uncommon in the genitourinary tract. Most reported cases have been located in the urinary bladder or urachus. Villous adenoma arising in the renal pelvis or ureter is very rare. We present a case of an 81-year-old female who presented with difficulty voiding and mucosuria. A computed tomography scan identified right-sided hydronephrosis, renal parenchymal atrophy, nonobstructing calculi and a lower pole renal mass. She underwent open right nephrectomy. Histopathologic examination of the kidney revealed an intestinal type villous adenoma of the renal pelvis with high-grade dysplasia and focal areas suspicious for invasive adenocarcinoma. We review the four previously reported cases of intestinal type villous adenoma in the renal pelvis and discuss diagnosis and management of this unusual neoplasm.

BackgroundWe report a case of primary mucinous cystadenocarcinoma of renal pelvis which radiologically resembled large multicystic mass in 45 years old man.Case PresentationThe patient referred to our center with loin pain and progressive abdominal distention from 4 years ago. In the previous published literature, four cases of mucinous cystadenocarcinoma of renal origin have been published. Abdominal CT showed complete replacement of left kidney by a large multiloculated cystic mass accompanied with multiple large nephrolithiasis. Nephrectomy was performed and histopathology revealed covering of epithelium of renal pelvis by columnar epithelium and scattered goblet cells and mucous gland.ConclusionMucinous cystic neoplasms of kidney are rare entity and our case and few similar reported cases showed that this tumor is an unique clinicopathologic renal mass that may be classified by World Health Organization classification in the future

“…The normal urological system is lined by stratified cuboidal epithelium, also known as transitional epithelium or urothelium. It is well recognized that the urothelium can undergo squamous and glandular metaplasia [9]. Metaplasia of the bladder urothelium occurs commonly in response to local injury.…”
