Derqaoui Sabrine, Boujida Ismail, Rouas lamia, Lamalmi Najat

Lymphoblastic lymphomas are immature lymphoid malignancies accounting for approximately 30% of non Hodgkin lymphoma in children. Most of these neoplasms originate from T cell precursors while less than 25% of them originate from B lymphoblasts. On histology and immunohistochemistry, lymphoblasts in B lymphoblastic lymphoma (BLL) and B lymphoblastic leukaemia share the same features. However, they represent different diseases with distinct molecular alterations. Herein, we describe a case of BLL in a 2-year-old child presenting as a paravertebral mass, including the clinical and histopathological features with a review of the current literature.
