Abstract

ABSTRACT:Objective:To investigate prognostic indicators in an aggressive Crooke's cell adenoma of the pituitary.Methods:The surgically removed tumor was studied by histology, immunohistochemistry and transmission electron microscopy.Results:An aggressive invasive sellar tumor removed by repeated surgeries from a 43-year-old woman with pituitary related Cushing's disease was classified as a Crooke's cell adenoma of the pituitary. The application of several cell proliferation markers confirmed the aggressive nature of the tumor.Conclusions:The investigation of the present case provides additional evidence that pituitary Crooke's cell adenomas may possess aggressive behavior.
