Figure 1

Histopathology demonstrating the normal tonsillar tissue with areas of deep ulceration at 4x (a) and 10x (b) magnification. At 40x magnification, the large immunoblasts and the occasional Reed–Sternberg-like cells are demonstrated in the centre of the ulcer (c). The larger immunoblasts demonstrated positive staining for CD-30 (d), EBERish (e), and MUM-1 (f).
