Figure 1: September 2008 Well-defined red to violaceous nodule with a central healed scar (a) and popliteal fossa with multiple well-defined mildly erythematous annular lesions with raised edges (b). Histopathology of the nodular lesion showing an infiltrate of predominantly small lymphocytes with scattered large atypical epithelioid cells (c= H and E, ×4 and d= H and E, ×20) and immunohistochemical stains showing diffuse positive staining of lesional cells (e= CD20, ×4 and f= bcl-6, ×4). Diagnosis at our institution was follicle center cell lymphoma
