BURGOS CANALES, Sebastián et al. Leukemic transformation in a patient with follicular lymphoma and hyperleukocytosis at diagnosis. Rev Cubana Hematol Inmunol Hemoter [online]. 2018, vol.34, n.1, pp.83-88. ISSN 0864-0289.

Follicular lymphoma rarely presents with a leukemic phase and this should be considered a negative prognostic factor. Also, follicular lymphoma and myelodysplastic syndrome association has not been previously reported. Herein we present a patient who debuted with marked hyperleukocytosis and was diagnosed with follicular lymphoma, receiving CHOP-R and FCR after she relapsed. Several months later, secondary myelodysplastic changes were observed in her bone marrow. She received supportive therapy and finally progressed into acute myeloid leukemia. Although secondary myelodysplasia is known to be produced by chemotherapy, this patient additionally had trisomy 11, previously described in myelodysplasia and Burkitt's lymphoma, which could be linked to progression to acute myeloid leukemia.

Palavras-chave : hyperleukocytosis; follicular lymphoma; leukemic phase; secondary myelodysplasia; trisomy 11.
