Figure 2 :Photomicrograph shows a classical CM (a; ×40). Glandular structures can be seen within the myxoma surrounded by stellate cells and myxoid areas (b; H and E, ×200). Special stains show mixed intra and extracellular acid mucin (c; AB-PAS, ×200) as well as neutral mucin (d; mucicarmine ×200). The glandular structures and stellate cells show positivity for vimentin (e; ×40), EMA (f; ×40), CK-7 (inset: CK-20 stain is negative) (g; ×400; inset: ×400) and CEA (luminal positivity) (h; ×400). Calretinin positivity is seen in epithelial cell nuclei (inset: calretinin positivity in vessel wall) (i; ×200; inset: ×200)
