QUESTION 45.7




A.  3



B.  5



C.  7



D.  9



E.  10




  8.  Gleason score assessed in needle biopsies is a powerful predictor of the pathologic findings in prostatectomy specimens, prognosis after radical prostatectomy, and prognosis following radiotherapy.

B.  4 to 5



C.  5 to 6



D.  6 to 7

D.  Benign prostatic hyperplasia



E.  Mucous gland metaplasia




12.  A section of a prostatic needle biopsy is immunohistochemically stained for alpha-methyl acyl-CoA racemase (AMACR). The result is shown in this picture. Which of the following is the most likely diagnosis?



Image


QUESTION 45.12




A.  Adenocarcinoma



B.  Atrophic gland



C.  Atypical adenomatous hyperplasia (adenosis)



D.  Benign prostatic hyperplasia



E.  Mucous gland metaplasia
