Follicular lymphoma (FL), a well defined mature B-cell lymphoma, rarely presents with great morphological variations that could mimic either other malignancies or disguise themselves with only subtle neoplastic feature. In the second part of this series, we present more FL morphologic variants, including FL with signet ring cells, FL with HRS-like cells, FL with anaplastic/pleomorphic cells, FL with sclerosis, FL microlymphoma, FL with prominent sinus histiocytosis, and FL neurolymphomatosis. Although uncommon, some of these FL variants pose diagnostic pitfalls for the practicing pathologists.
