Follicular T-cell lymphoma.

Follicular T-cell lymphoma is a recently described, rare neoplasm with the true incidence still unknown. It is a lymph node-based tumor in which the node shows a follicular pattern of growth. Immunohistochemistry confirms the cells of origin to be follicular helper T-cells and thus plays an important role in the diagnosis of the tumor. We report a case of follicular variant of peripheral T-cell lymphoma, which was erroneously reported as Hodgkin lymphoma on fine-needle aspiration, and follicular lymphoma on hematoxylin and eosin.
