INTERPRETATION AND
DIAGNOSIS: (mxv) 09/20/2012 @ 01:54 pm
LEFT NECK MASS (EXCISION): CLASSICAL HODGKIN
LYMPHOMA, MIXED
CELLULARITY TYPE. SEE NOTE.
NOTE: The specimen contains
sections of lymph node. The
architecture is effaced by a diffuse
inflammatory infiltrate
containing prominent clusters of epithelioid
histiocytes and
lymphocytes. There are scattered
Reed-Sternberg and variant cells as
well as mummified cells present within the
lymph node.
A panel of immunostains performed at JHH
(CD20, CD3, CD30, CD15, and
Pax-5) and in situ hybridization for EBV
(EBER) was reviewed. The
background lymphocytes contain a mixture of
CD20 positive B-cells and
CD3-positive T-cells, with T-lymphocytes
predominating. The
Reed-Sternberg and Hodgkin cells show a
strong membrane staining for
CD30 and CD15, and a weak nuclear staining
for Pax-5. An in situ
hybridization for EBV-encoded RNA (EBER) is
negative.
The findings are consistent with classical
Hodgkin lymphoma, mixed
cellularity type.

by which I attest that
the above diagnosis is based upon my personal
examination of the
slides (and / or other material indicated in
the diagnosis), and
that I have reviewed and approved this
report.
Some stains/tests used in arriving at the
diagnosis were performed
here using reagents that have not been
cleared or approved by the
US Food and Drug
Administration. These were developed and their
performance characteristics determined by the
Johns Hopkins Medical
Laboratories. Their use does not
require FDA approval.
