case_images: Seventy percent of the tumour bulk was removed and tissue sample was sent for histopathological examination (Figure 3).
case_images: 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).
