Abstract
Lymphoblastic lymphoma (LBL) with an early T-cell precursor phenotype has only been rarely reported. Nijmegen breakage syndrome (NBS) is an inherited chromosomal instability disorder with known predisposition to malignancies that is very rare as well. We report a case of early T-precursor LBL (ETP-LBL) in a patient with NBS, a rare combination that has not been reported. We raise the question of whether a chromosomal instability disorder such as NBS increases the propensity for early T-precursor acute lymphoblastic leukemia/lymphoma (ETP-ALL/LBL), given that ETP-ALL has been shown to have increased genomic instability compared to T-ALL.
期刊介绍:
The Journal covers the spectrum of disorders of early development (including embryology, placentology, and teratology), gestational and perinatal diseases, and all diseases of childhood. Studies may be in any field of experimental, anatomic, or clinical pathology, including molecular pathology. Case reports are published only if they provide new insights into disease mechanisms or new information.
