Pituitary adenoma from a 22-year-old man with acromegaly

(Hematoxylin and Eosin, x 100) The patient underwent transsphenoidal surgery with complete tumor resection. Histological examination showed a highly vascularized pituitary adenoma with a diffuse (solid) growth pattern. Higher magnification in this image shows uniform cells with broad eosinophilic cytoplasm and round-to-oval nuclei. (Source: Gosau M, Vogel C, Moralis A, Proff P, Kleinheinz J, Driemel O.
