(a) Benign mesenchymal lesion (nodular fasciitis) cytology: myxoid background matrix with dispersed fibroblasts (Giemsa ×100). (b) Nodular fasciitis: plump, randomly oriented spindle shaped cells surrounded by myxoid stroma with dominating fibrous component (inset, Masson Trichrome) (H&E ×200). (c) Benign mesenchymal lesion (extra-abdominal desmoid) cytology: loosely arranged fibroblast-like cells with ovoid nuclei and greyish blue cytoplasm (Giemsa ×100). (d) Extra-abdominal desmoids: cellular proliferation of bland spindle shaped cells arranged into ill-defined long fascicles along with infiltration of spindle cells (inset) between skeletal muscle and fat (H&E ×100).
