Figure 3: (a) The tumor cells showing diffuse nuclear positivity for PAX8 (IHC, X200) (b) The biphasic tumor cell population showing diffuse membranous positivity for CK7 (IHC, X200) (c) Cyclin D1 showing selective immunostaining restricted to the larger squamoid cells in the centre of the alveolar spaces. (IHC, X200) (d) The tumor cells were negative for p40 (IHC, X100)
