    Slide 149: Pituitary adenoma

    This gross photo of the brain with the adenoma was initially published in Laboratory Medicine, volume 29, number 10, page 612.  It had been submitted as one of the photographs in the 1998  Art and Science of Medicine Photography contest.  It was taken and submitted  by Dr. James M. Gulizia of Brigham and Women's Hospital, Boston.

    This picture is of a "benign" pituitary adenoma. Although biologically benign, it is sure in the wrong place and can be lethal just because of its location. You will see clusters and cords of the tumor cells, and it may be tricky to distinguish the tumor from the surround normal pituitary. Does the term "tumor" apply here? You should see no mitoses.
