A Immunohistochemical staining with an h-caldesmon antibody was performed on the iliac lymph node, which showed strong positivity in differentiated muscular cells (thin arrows). The intranodal coelomic tissue (thick arrow) is negative for the muscular marker (h-caldesmon, × 100). B A progressive differentiation of coelomic remnants into muscular tissue (h-caldesmon, magnification × 250)
