case_images: Gross pathological examination (Figure 2) revealed grey-white, cylindrical tissue measuring 50 x 45 x 15 mm.
case_images: The tumor cells are nested, with a large number of lymphocytes infiltrating between cells and stroma. H&E x 50.

case_images: Tumour cells were organised in nests with extensive lymphocyte infiltration between the cells and within the stroma (Figure 3).
case_images: At high magnification, the nuclei of the tumors were round, oval, or elongated, vacuolated, with prominent nucleoli. H&E x 400.
