Photomicrographs showing the histological and immunohistochemical features of the lesion. The tumor tissue was composed of sheets of cells arranged in a predominantly papillary pattern with perivascular pseudo-rosettes. Tumor cells in the papillary area displayed abundant eosinophilic cytoplasm, vesicular nuclei (A) (original magnification ×100). The immunohistochemistry profile showed positivity for EMA (B), vimentin (C) and MIB-1 (D) (original magnification ×200). The insert in A represents a higher magnification of the outlined area (original magnification ×400).
