I got a copy of my pathology report. Here’s the relevant part:

 

IHC Interpretation:

The staining pattern hilights CD15 and CD30 positive Reed-Sternberg cells in a background of mixed inflammatory cells including CD20 positive B-cells and CD3 positive T-cells. Pax-5 stains the Reed-Sternberg cells with less intensity than the normal B-cell population. These findings are all consistent with Hodgkin’s lymphoma.

 

Final diagnosis:

Lymph node, (right level V), excision: Hodgkin’s lymphoma, nodular sclerosing type. See comment.

 

Comment:

Histologic sections are of a lymph node with an effaced architecture by collections of mature lymphocytes mixed with eosinophils and numerous Reed-Sternberg cells and variants. There are bands of fibrosis consistent with an early form of nodular sclerosing Hodgkin’s. No immunophenotypically abnormal B- or T-cell populations were identified by flow cytometry (see Hematopathology report HP05-5206)."
