RESUMO
ABSTRACT: Plasmablastic transformation of follicular lymphoma is very rare and has been reported in only 5 cases till date. We report a case of simultaneous identification of extranodal, soft tissue plasmablastic lymphoma in the ankle and bone marrow involvement by follicular lymphoma. This unusual case presentation is a challenge for the treating physician with the patient becoming resistant to chemotherapy and succumbing to the disease within a few months of diagnosis. These cases are known to have an aggressive clinical course with very poor prognosis and survival rate of less than 6 months. This report broadens the spectrum of morphological transformation of follicular lymphoma and it may represent a new category of high-grade transformation of follicular lymphoma.
