D.  Mesonephroid metaplasia



E.  Reactive change





  2.  A middle-aged woman presents with a 3-month history of suprapubic discomfort, dysuria, and frequency. Urine cultures are negative. The finding of mucosal fissures on cystoscopy and mucosal/submucosal chronic inflammation with mast cells on biopsy is most consistent with:




A.  Cystitis glandularis



B.  Follicular cystitis



C.  Interstitial cystitis



D.  Malakoplakia



E.  Ulcerative cystitis




  3.  A 68-year-old woman undergoes excision of an easily bleeding polypoid mass protruding through the urethral meatus. Histologically, it is composed of vascular tissue with chronic inflammatory cells and islands of squamous epithelium. The most likely diagnosis is:

D.  Urethral carcinoma



E.  Urethral caruncle




  4.  A plaque of the urinary bladder mucosa is biopsied. The biopsy shows a mixed inflammatory infiltrate predominantly located within the lamina propria, consisting of nodules of histiocytes surrounded by lymphoid aggregates. As shown by this picture, there are round laminated inclusions. Which of the following mechanisms is related to this lesion?

A.  Lamina propria



B.  Muscularis propria



C.  Pelvic wall



D.  Perivesical fat



E.  Prostate




  7.  Biopsies of a 2.0-cm exophytic tumor in the bladder trigone of a 57-year-old man show papillary structures lined by more than 10 layers of epithelial cells. Nuclear atypia is moderate, mitoses are rare, and there are foci of necrosis. The neoplasm infiltrates the underlying muscularis propria. Which of the following is the most important parameter influencing the prognosis?

B.  Infiltration of the muscularis



C.  Mitoses



D.  Necrosis



E.  Nuclear atypia




  8.  A 60-year-old woman without prior history of cancer presents with newly onset right hemiparesis. An MRI shows a ring-enhancing mass in the left frontal lobe.

A.  Kidney



B.  Lungs



C.  Prostate



D.  Skin



E.  Urinary bladder

12.  A 66-year-old man presents with dysuria, urgency, and microscopic hematuria. Following cytologic studies and cystoscopy, biopsies reveal the presence of the lesion shown in this picture. Which of the following is true about this lesion?



Image


QUESTION 44.12




A.  Characterized by full-thickness cellular atypia.



B.  Detected usually in association with papillary or invasive tumors.



C.  High nuclear–cytoplasmic ratio is always present.



D.  Manifests usually with dysuria and hematuria.



E.  Umbrella cells are always absent.




13.  Of the following types of urothelial carcinoma (UC) with divergent differentiation, which one is the most common?




A.  Sarcomatoid UC
