Immunohistochemical Study of Ki-67 Labelling Index in Neoplasms of Central Nervous System [PDF]

National Journal of Laboratory Medicine, 2022
Introduction: The central nervous system tumours show a varied histopathological spectrum. The cell proliferation index may provide an objective method for assessing tumour biology. The Ki-67 is considered to be the most reliable proliferative marker

Atypical Central Neurocytoma [PDF]

Journal of Neuropathology and Experimental Neurology, 1997
The proliferative potential of central neurocytomas was determined in a biopsy series of 36 cases and compared with clinical outcome. The mean size of the growth fraction, as determined by MIB-1 labeling index (MIB-1 LI) at first biopsy, was 2.8 +/- 2.5 with a range of 0.1 to 8.6%.

Atypical Central Neurocytoma With Sarcomatous Differentiation [PDF]

Archives of Pathology & Laboratory Medicine, 2014
We report a case of an intraventricular tumor with features of atypical central neurocytoma with a sarcomatous component in a 44-year-old woman who presented with headaches and vomiting. Magnetic resonance imaging revealed a 3.4-cm lobulated enhancing mass in the occipital horn of the left lateral ventricle, and the patient subsequently underwent a ...
