Digital cases

- HPC:187 (HPC:187) : T-cell lymphoblastic lymphoma
- HPC:344 : T-cell lymphoblastic lymphoma

Subtypes

- precursor T lymphoblastic lymphoma (surface CD3+) (80%)

- precursor B lymphoblastic lymphoma (CD20+, CD19+ or CD79a+)

  • B-cell lymphoblastic lymphoma represents approximately 15% of all cases of lymphoblastic lymphoma.
  • B-cell lymphoblastic lymphoma is most common in older children and young adults.

- non-B, non-T lymphoblastic lymphoma (B cell marker- and surface CD3-) (5%)

  • CD7+ stem cell lymphoma (CD7+SCL) [CD4-, CD7+, CD33+/-, CD56-]
  • blastic natural killer cell lymphoma (B-NKL) [CD4-, CD7+/-, CD33-, CD56+, CD123-]
  • myeloid/NK precursor cell leukemia (M/NKL) [CD4-, CD7+, CD33+, CD56+], and 4)
