This subtype of prostatic carcinoma overall has a better prognosis than the usual acinar type:Small cell carcinomaMucinous adenocarcinoma Ductal carcinomaSignet ring carcinoma Adenoid basal cell tumor (adenoid cystic tumor) 2. The following statements regarding normal prostate are true, EXCEPT:Anterior fibromuscular stroma occupies approximately 1/3 of the prostate, contains very few glands and consists of smooth muscle and dense fibrous tissue Skeletal muscle of the urogenital diaphragm extends into the prostate in its most apical aspectLipofuscin pigment helps differentiate seminal vesicle tissue from prostatic glands Large number of neuroendocrine cells are present in prostatic epitheliumDenonvillier's fascia separates the prostate and seminal vesicles from the rectum 3. All of the statements concerning a fibroepithelial polyp of the bladder are true, EXCEPT:It represents a mesenchymal tumor This lesion has no malignant potential There is a female predominanceIt is mostly found in children and young adults It occurs most commonly at the ureteropelvic junction and upper ureter 4. A 3 year old boy presents with a large abdominal mass consistent with neuroblastoma. All of the following statements regarding this condition are correct, EXCEPT:Two characteristic genetic events are loss of a distal region of chromosome 1p and amplification of N-myc oncogene Hemorrhage, calcification and necrosis are common macroscopic features It is associated with the Beckwith-Wiedemann syndrome, Hirschsprung's disease and neurofibromatosisOver 80% are detected in children under the age of 4 Histologically, the most prominent feature is presence of Homer Wright rosettes 5. 63 year old male with a history of bilateral ocular MALT lymphoma treated with radiation therapy. He now presents with diffuse pelvic infiltrative process involving the bladder, prostate, seminal vesicles, rectosigmoid, distal ureters, and adjacent muscles. Bladder and prostate biopsies were performed. Based on histology, the process is most consistent with:Idiopathic retroperitoneal fibrosis Recurrent MALT lymphoma High-grade lymphoma Invasive transitional cell carcinoma (urothelial neoplasm) High grade prostatic adenocarcinoma 6. If seen on a prostate core biopsy this prostatic adenocarcinoma would be best graded as Gleason score =3 for 60%, Gleason score = 4 for 25%, and Gleason score = 5 for 15%. How would the case be scored overall?Gleason score 3 + 4 = 7/10 Gleason score 3 + 3 = 6/10 Gleason score 4 + 5 = 9/10 Gleason score 3 + 5 = 8/10 Gleason score 5 + 3 = 8/10 7. All of the following parameters are associated with adverse outcome in prostatic carcinoma, EXCEPT:Perineural invasion Positive surgical marginsNodal metastases Extraprostatic extensionInvolvement of seminal vesicle 8. All of the following statements are correct regarding this kidney neoplasm, EXCEPT: GU Pathology - Part 1, Case #5 GU Pathology - Part 1, Case #5 GU Pathology - Part 1, Case #5It is associated with Beckwith-Wiedemann and Denys-Drash syndromes 90% of the cases occur before the age of 6 Lesions are divided into favorable and unfavorable histology groups based on the degree of anaplasia Staging is the most important prognostic determinator It always has three components: undifferentiated blastema, mesenchymal tissue and epithelial tissue 9. A 42 yo female presented with hypertension, Cushing's syndrome and virilization. A representative section from her resection specimen is consistent with an adrenal cortical carcinoma. All of the following features are part of diagnostic criteria for this tumor EXCEPT:Tumor weightCellular pleomorphismTumor necrosis Vascular invasionDiffuse growth pattern Loading...
