Image Description
Large B-cell Lymphoma of the Testis in a background of CLL/SLL (same case as the previous five images): The upper portion of the image shows the CLL/SLL component which had the following immunophenotype: CD19+, CD20 dim+, CD5+, CD23 variable+, and kappa dim+. The lower portion shows the large B-cell lymphoma which was CD19+, CD20 mod+, CD5-, CD23-, and CD10+.
This may be a composite lymphoma (a CD10+ large B-cell lymphoma along with a co-existing CLL/SLL) OR a progression/transformation of CLL/SLL.
