Slide 1-

Pathology of Kidney and the Urinary tract Dr. Amar C. Al-Rikabi Dr. Hala Kassouf Kfoury
Slide 2-

Benign and Malignant Tumours of the Kidney and Urinary Bladder Lecture -5
Slide 3-

Objectives: At the end of the lecture the students will be able to: Recognize the benign tumors of the kidney. Describe renal cell carcinoma and Wilm’s tumor. Recognize transitional cell and squamous carcinoma of the urinary bladder.
Slide 4-

RENAL NEOPLASMS AND CYSTS Neoplasms of the Renal Parenchyma Renal cell carcinoma (renal adenocarcinoma; hypernephroma) Nephroblastoma (Wilms's tumor) Urothelial tumors
Slide 5-

RENAL NEOPLASMS AND CYSTS Gross pathology and histology Histogenesis Clinical manifestations Diagnosis: radiographic imaging Treatment and prognosis Pathophysiology
Slide 6-

Kidney with ischemic atrophy also bears very small subcapsular adenomas near to each pole.
Slide 7-

Histology of a subcapsular papillary adenoma shows tubules arranged in a papillary fashion.
Slide 8-

Human renal cell carcinoma
Slide 9-

Renal cell carcinoma Renal cell carcinoma is the most common primary renal tumor in adults and may be occult.
Slide 10-

Small clear cell renal cell carcinoma (hypernephroma, Grawitz tumor) is spreading into perirenal adipose tissue.
Slide 11-

Human renal clear cell carcinoma
Slide 12-

Typical lobulated, whorled, tan-colored cut surface of renal cell carcinoma.
Slide 13-

Invasion of the renal vein and inferior vena cava (arrow) by renal cell carcinoma.
Slide 14-

Papillary urothelial (transitional cell) carcinoma of renal pelvis. Note the exophytic, multifronded nature of the tumor. Transitional cell carcinoma of the renal pelvis.
Slide 15-

Moderately differentiated urothelial carcinoma of bladder.
Slide 16-

Solid, bulging, fleshy tan-white, partially necrotic tumor has replaced much of the kidney and is encompassed by a thin rim of renal tissue.. Wilms’ tumor (nephroblastoma)
Slide 17-

This Wilms’ tumor appears whiter due to formalin fixation and has extended beyond the confines of the kidney
Slide 18-

Histology shows hypercellular areas comprising undifferentiated blastema, loose stroma with undifferentiated glomeruloid body. Wilms’ tumor
Slide 19-

Urothelial (transitional cell) carcinoma in situ of the urinary bladder if untreated, up to 75% of cases go on to invasive cancer.
Slide 20-

Histology of carcinoma in situ (surface is to the right).
Slide 21-

Invasive urothelial carcinoma of the bladder is invading the muscle coat on the right side of the picture.
Slide 22-

Moderately differentiated urothelial carcinoma of bladder.
Slide 23-

Advanced urothelial cancer of the bladder has spread posteriorly (arrow)to invade the uterus.
Slide 24-

Poorly differentiated urothelial carcinoma.
