Background: Renal involvement is rare in B lymphoblastic lymphoma (B-LBL). The authors describe a rare case of renal involvement in a 21-year-old male patient with B lymphoblastic lymphoma leukemia, presenting with severe lactic acidosis.
Methods: Hematologic investigation, bone marrow aspirate and biopsy, cytogenetic analysis and renal biopsy were performed.
Results: The patient achieved complete hematological remission (CHR) after induction therapy with the regimen of VDCP and received consolidation chemotherapy regularly. He remained CHR until now.
Conclusions: Renal biopsy, bone marrow aspirate, and biopsy are important to confirm a correct diagnosis. Renal involvement in B-LBL as a prognostic factor needs further studies.
