AB009. Distinct clinical profiles and treatment outcomes in invasive pituitary adenoma and Crooke cell tumor: a comparative case report

These cases underscore the heterogeneity of pituitary adenomas, emphasizing the importance of the Ki-67 index as a prognostic marker.

A multidisciplinary approach is crucial for optimizing patient outcomes in the management of these tumors.
