Most of the tissue resected appears cauterized, probably due to rich vascularity and intraoperative bleeding. I see epithelial structures lined by somewhat atypical glandular epithelia. In the sphenoid sinus and clivus region, these would certainly suggest an adenocarcinoma of metastatic origin. However, examination of less cauterized areas, if any, is essential. Immunohistochemistry (AE1) may help. The photos do not look like that from a meningioma or pituitary adenoma.
