Seventy percent of the tumour bulk was removed and tissue sample was sent for histopathological examination (Figure 3).
The vallecular tissue has benign stratified squamous epithelium with the underlying stroma diffusely infiltrated by neoplastic lymphoid cells (H&E, 200x). The neoplastic cells are monotonous and medium cell size. The inset: They are composed of centrocytes displaying cleaved nuclei, inconspicuous nucleoli and scanty cytoplasm. Some mitotic figures are present (arrow). Reactive small lymphocytes are interspersed in between the neoplastic cells (H&E, 400X).
