Fine needle aspiration cytology and flow cytometry in the diagnosis and subclassification of non-Hodgkin's lymphoma based on the World Health Organization classification.

Objective: To determine the usefulness of fine needle aspiration cytology (FNAC) in combination with flow cytometry on the new World Health Organization (WHO) classification of malignant lymphoma.
