*The skin tumors result from proliferation of undifferentiated mesenchymal cells which become large stellate cells (myxoma cells). These cells may contain intracytoplasmic eosinophilic inclusions. These cells lie in a homogeneous matrix of mucinous material interspersed with capillaries and inflammatory cells. Endothelial proliferation with narrowing of the lumen and extrusion of stellate "myxoma" cells has been described. | *The skin tumors result from proliferation of undifferentiated mesenchymal cells which become large stellate cells (myxoma cells).
