though ancillary investigative methods, including flow cytometry and molecular study, are of limited value in fine-needle aspiration cytology assessment of AILD-T due to the heterogeneous cell population present, recognition of the peculiar combination of cytologic features, especially in the right clinical setting, should provide a clue about the diagnosis. A high index of suspicion is essential to avoid a false negative diagnosis of reactive lymphadenopathy.
