CSF Involvement by Nonhematolymphoid Malignancies: A Descriptive Study with Emphasis on Cytomorphological Clues.

Introduction: Detection of malignant cells in cerebrospinal fluid (CSF) samples in suspected cases of malignancy is critical for the management of patients. CSF involvement by nonhaematolymphoid malignancies is less common. We aimed to study the cytomorphologic characteristics of various nonhaematolymphoid malignancies in CSF.
