Lymphoblastic lymphoma

Chapter: 20b
High grade non-Hodgkin lymphoma, which is the solid tissue counterpart of ALL. Most cases are of T-cell phenotype, and more than half of the patients present with a mediastinal mass (suggesting origin in the thymus). T lymphoblastic lymphoma is most common in adolescent and young adult males, often spreads to the bone marrow with subsequent leukemia and has an overall poor prognosis.
