Introduction:
The expression of T-cell-associated antigens on diffuse large B-cell lymphoma (DLBCL) is uncommon. The coexpression of ≥2 T-cell-associated antigens on DLBCL is even rarer. This has been reported in the literature only a few times, most commonly coexpression of either CD5 or CD8 and a second, different T-cell marker.
Case Presentation:
This case report features a patient who presented with a rapidly evolving head and neck mass that displayed coexpression of CD5 and CD8.
Conclusion:
In this case report, we present the first case to our knowledge of DLBCL with coexpression of only CD5 and CD8.
