Image Description
Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL): Most lymphocyte-predominant (LP) cells are surrounded by T cells expressing CD3, CD4, CD57, and PD1 forming rosettes or collarettes. This image shows PD1 positive T-cells forming rosettes around LP cells.
The presence of T-cell rosettes around CD20+, BCL6+ LP cells is a useful diagnostic feature of NLPHL and helps distinguish it from progressively transformed germinal centers, mixed cellularity Hodgkin lymphoma, and T cell/histiocyte-rich B cell lymphoma.
