Case report: T lymphoblastic lymphoma

MPHO Type: 
Estimated frequency: 
Most recent risk assessment for leukemia (Council of Europe, 2018): donors with active leukemia are considered to represent an unacceptable risk for tumor transmission. Data at this time do not allow for discrimination of individual types of leukemias. Donors with treated leukemia after a disease-free interval of 5 to 10 years are assumed to represent a high risk for tumor transmission.
Time to detection: 
6 months
Alerting signals, symptoms, evidence of occurrence: 
The female recipient developed general malaise 6 months after transplantation. A mild leukopenia and thrombocytopenia was noted. Bone marrow biopsy revealed massive infiltration of blasts. The morphologic features of cells were similar to lymphoblastic lymphoma, expressing cyCD3+, Tdt+, CD1a+ and CD8+.
Demonstration of imputability or root cause: 
Inmunophenotyping analysis showed the same antigenic profile of the abnormal T cells in the thymus of the donor and the bone marrow of the recipient. FISH studies for sex chromosomes were used to prove that the blastic cells in the recipient came from the donor. PCR confirmed the clonal origin of the blasts in the recipient.
Imputability grade:

Expert comments for publication: 
To the author's knowledge, this is the first report of acute T cell lymphoblastic leukemia transmission from a donor with malignant T cell lymphoblastic lymphoma. Nevertheless, this paper was published in 2008, so to this date there might have been other published cases
