Immunohistochemical results. The tumor resulted diffusely and strongly positive for CD34 (a) and MUC4 (b). The tumor cells were also positive for EMA and SMA, but in a patchier manner (c, d).

Conversely, tumor cells showed PTEN loss of expression, particularly in the nuclei, while appeared retained in endothelial cells (f)
