Figure 1

A circumscribed fibrous lesion covered by acanthotic epithelium showing lipomatous content at the centre of connective tissue (a). Mature adipose tissue in a background presenting ropey collagen fibers bundles (b). Spindle cells, vessels, and mast cells near lipomatous content ((c)-(d)). Spindle cells were strongly positive for CD-34 antibody (e) and positive for Bcl-2 (f) and vimentin antibodies (g). The great number of mast cells was demonstrated by mast-cell staining (h). ((a) to (d)) Hematoxylin and eosin stain; ((d) to (h)) immunohistochemistry stain.
