Burkitt lymphoma vs Diffuse large B-cell lymphoma

How to tell Burkitt lymphoma and Diffuse large B-cell lymphoma apart when a board question makes them look alike.

Fastest separator

Burkitt is MYC/t(8;14), starry-sky, very fast; DLBCL is diffuse large B-cell sheets without the classic MYC-star pattern.

Side by side

Burkitt lymphomaDiffuse large B-cell lymphoma
Key clue

Burkitt lymphoma is a highly aggressive MYC-driven B-cell lymphoma with t(8;14), starry-sky histology, very high Ki-67, and either a jaw mass in endemic disease or an abdominal/ileocecal mass in sporadic disease.

Diffuse large B-cell lymphoma is an aggressive lymphoma of large atypical B cells, often in older adults, with rapidly enlarging nodal or extranodal mass.

Mechanism

MYC overexpression drives rapid cell cycling, producing very high tumor turnover and starry-sky macrophage cleanup.

DLBCL arises from transformed mature B cells with heterogeneous genetic drivers and diffuse sheets of large malignant cells.

Labs and tests

t(8;14) involving MYC and immunoglobulin heavy chain, CD10 positivity, high Ki-67, and starry-sky pattern support Burkitt lymphoma.

Sheets of large CD20-positive B cells with subtype-specific markers support DLBCL.

The trap

Both are aggressive B-cell lymphomas, so MYC translocation, age/location pattern, and histology separate them.

The repair move

For aggressive B-cell lymphoma, look for MYC/starry-sky before calling every fast mass DLBCL.

Core

A child has a rapidly enlarging jaw mass. Biopsy shows a starry-sky pattern, nearly 100% proliferation index, CD10-positive B cells, and t(8;14) involving MYC. Which diagnosis is most likely?

Show answer and explanation

Answer: A. Burkitt lymphoma. MYC t(8;14) with starry-sky histology points to Burkitt lymphoma.

Why the other choices are tempting

  • B. DLBCL has diffuse large B cells but lacks the classic MYC/starry-sky package.
  • C. Follicular lymphoma has t(14;18) and BCL2 overexpression.
  • D. Mantle cell lymphoma has t(11;14) and cyclin D1 overexpression.
  • E. Hodgkin lymphoma has Reed-Sternberg cells.
