===Microscopic description=== | |||
The sections show a tumour composed of irregular anatoming cords of physaliferous cells resting on a myxoid background. Mitotic activity is not detected. | |||
Immunostains demonstrate that the tumour cells intensely express cytoplasmic for low molecular weight keratin (LMWCK) and membranous epithelial membrane antigen (EMA). There is weak, focal cytoplasmic expression of S100. | |||
