Abstract

Splenic marginal zone lymphoma (SMZL) most commonly presents with splenomegaly and stage IV disease. To our knowledge, there have been only two reported cases of SMZL without associated splenomegaly; one was detected 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 incidentally following a motor vehicle accident; monoclonality was confirmed by polymerase chain reaction analysis of paraffin-embedded tissue owing to the inability of confirmation by immunohistochemical techniques. We describe our findings and emphasize the importance of recognizing early stages of SMZL in incidental splenectomies by polymerase chain reaction analysis of paraffin-embedded tissue. Frozen tissue is not generally available in such cases.
