Ch. Dunphy et al., INCIDENTAL EARLY DETECTION OF A SPLENIC MARGINAL ZONE LYMPHOMA BY POLYMERASE CHAIN-REACTION ANALYSIS OF PARAFFIN-EMBEDDED TISSUE, Archives of pathology and laboratory medicine, 122(1), 1998, pp. 84-86
Splenic marginal zone lymphoma (SMZL) most commonly presents with sple
nomegaly and stage IV disease. To our knowledge, there have been only
two reported cases of SMZL without associated splenomegaly; one was de
tected incidentally after a bicycle accident. This previously reported
case represented an early-stage SMZL with monoclonality confirmed by
immunohistochemistry. We report a case of early-stage SMZL detected in
cidentally following a motor vehicle accident; monoclonality was confi
rmed by polymerase chain reaction analysis of paraffin-embedded tissue
owing to the inability of confirmation by immunohistochemical techniq
ues. We describe our findings and emphasize the importance of recogniz
ing early stages of SMZL in incidental splenectomies by polymerase cha
in reaction analysis of paraffin-embedded tissue. Frozen tissue is not
generally available in such cases.
