Abstract
A case of benign mesenchymoma that occurred in the cheek is presented. The tumor consisted of an admixture of such mesenchymal elements as mature fat tissue, blood vessels of varing size and shape with less organized muscular wall, fascicles of smooth muscle cells, and bone. Immunohistochemical examination revealed that many smooth muscle cells comprising the tumor were positive for desmin and α-smooth muscle actin but negative for vimentin. Such an immunohistochemical characteristic is very similar to that of non-vascular smooth muscle cells.
