A 5 cm mass is removed from a 41 y/o female which is found to have areas of smooth muscle cells, blood vessels, and fat. Special stains for HMB-45 were positive. This lesion is associated with all of the following conditions EXCEPT:von Hippel-Lindau (VHL) syndrome Tuberous sclerosis Birt-Hogg-Dube syndrome von Recklinghausen disease 2. The best diagnosis for the renal mass illustrated in the images below is which of the following: Renal Tumor Renal Tumor Renal Tumor Renal TumorNone of the above Wilm’s tumorMetanephric adenoma RhabdomyosarcomaRenal cell carcinoma, papillary type 3. The image below shows a renal tumor stained with Hale’s Colloidal Iron. The most likely diagnosis is: Renal Tumor Hale's Colloidal IronRCC, chromophobe type OncocytomaRCC, papillary type RCC, sarcomatoid type RCC, conventional type 4. An 18 y/o Caucasian male is found to have a renal tumor with clear cell RCC histology. It is important to perform cytogenetic analysis on this mass to look for involvement of which of the following chromosomes:None of the above3pChromosome 7Chromosome 11p13 Xp11.2 5. A 30 y/o African American male whose mother has sickle cell disease, is found to have a renal mass by CT examination. Which of the following are the most likely histologic features of this mass:Papillary cores filled with foamy macrophages admixed with other areas of tubular and solid architecture. The cytoplasm is acidophilic, and no clear cell component is identified. Clear cells with abundant cytoplasm, irregular nuclei, and a fine network of thin walled vessels surrounding nests of cells. Tubular Mucinous Spindle cell RCC Tubulopapillary architecture of infiltrating cells some with a hobnail like appearance. Tumor cell nuclei are high grade. Reticular / yolk sac-like pattern with focal areas having an adenoid-cystic pattern. 6. This tumor from the kidney illustrated in images below was negative for S-100 and desmin. In other areas of the tumor, RCC marker was focally positive. Which of the following is the best diagnosis? Renal Tumor Renal TumorRhabdomyosarcomaNone of the above RCC, Fuhrman grade IV Metastatic malignant melanoma Leiomyoma 7. According to the AJCC staging manual, all of the following affect the pathological staging of renal cell carcinoma EXCEPT:Fuhrman grade SizeRenal vein involvement Extension into perinephric fat Extension into renal sinus fat 8. The best diagnosis for the renal mass illustrated in the images below is which of the following: Renal Tumor Renal Tumor Renal TumorNone of the aboveRenal Cell Carcinoma, Papillary Renal Cell Carcinoma, ChromophobeRenal Cell Carcinoma, Conventional Oncocytoma 9. Which of the following is most helpful in differentiating chromophobe RCC from an oncocytoma:BinucleationPleomorphismPerinuclear halosGranular cytoplasm 10. Which of the following result in the highest stage for a renal cell carcinoma according to the 2002 AJCC staging manual:Tumor grossly extends into the vena cava above the diaphragmTumor grossly invades the wall of the vena cava Tumor invades beyond Gerota’s fasciaMetastasis to one single regional lymph nodeTumor directly invades adrenal gland 11. The best diagnosis for the renal mass illustrated in the images below is which of the following: Renal Tumor Renal Tumor Renal TumorRenal Cell Carcinoma, Chromophobe None of the above Renal Cell Carcinoma, Papillary Renal Cell Carcinoma, Conventional Oncocytoma 12. The best diagnosis for the renal mass illustrated in the images below is which of the following: Renal Tumor Renal Tumor Renal TumorNone of the aboveOncocytomaRenal Cell Carcinoma, Conventional Renal Cell Carcinoma, PapillaryRenal Cell Carcinoma, Chromophobe 13. An incidental renal lesion <1cm with papillary features and composed of predominantly clear cells is best classified as:Papillary carcinomaPapillary adenoma Renal cell carcinoma, clear cell type Renal cell carcinoma, NOSRenal cell carcinoma, chromophil type 14. A renal tumor has predominantly clear cells with the highest grade area containing cells with irregular nuclear border (size ~20m) and nucleoli visible from 10X. Many of the cells are noted to have eccentrically placed nuclei and eosinophilic cytoplasm. The best Fuhrman grade is:Fuhrman grade IVFuhrman grade IIIFuhrman grade IIFuhrman grade IFuhrman grade V Loading...
