Skeletal Muscle Involvement in B-Cell Lymphoma: Two Cases Illustrating the Contribution of Imaging to a Clinically Unsuspected Diagnosis

Figure 2

Transverse (a) and longitudinal (b) hematoxylin and eosin-stained histologic sections showing an infiltrate of intermediate-sized to large lymphoid cells in the endomysium between muscle fibers and the perimysium investing the fascicles or bundles of these fibers; these slides were prepared from the gluteal muscle biopsy of the 17-year-old boy described in case 1. On high magnification (c) one can observe the intimate association of the lymphoma cells with the individual striated muscle fibers.
