A 75-y-o man comes to the physician because of a 2-week history of moderate low back pain. Physical examination shows tenderness of the back and down each lower extremity on bending forward; there are no neuromuscular abnormalities. Rectal examination shows an enlarged prostate. Serum studies show a markedly increased prostate-specific antigen concentration. An x-ray of the spine shows vertebral collapse at L1 and patchy areas of increased density, consistent with osteoblastic metastases. Vertebroplasty is done to relieve the patient's pain, and a biopsy specimen of the damaged vertebra is obtained.
Histologic examination of the biopsy specimen is most likely to show which of the following findings?
A) Aggregates of proliferating plasma cells and plasmablasts
B) Nests of epithelial cells joined by intercellular bridges and containing keratin pearls
C) Pleomorphic epithelial cells forming duct-like structures
D) Sheets of small oval- to spindle-shaped basophilic cells
E) Sheets of uniform cells divided into lobules by fine fibrous septa containing lymphocytes
explain plz:sorry:
