An "abnormal" lymphoid proliferation simulating Hodgkin's disease in a burn patient

A particularly exuberant and unusual lymphoid proliferation in the spleen of a burn patient is presented. Many Reed-Sternberg cell variants and occasional diagnostic Reed-Sternberg cells strongly suggested a diagnosis of Hodgkin's disease. The pattern of distribution and cytology of this lymphoid infiltrate, however, are incompatible with Hodgkin's disease or a non-Hodgkin lymphoma. Morphologic features in this case suggest that the Reed-Sternberg cell is a B lymphocyte. The most probable etiologies of this unusual lymphoid proliferation are reviewed.
