Figure 3: Photomicrograph showing (a) Chromogranin immunostain showing cytoplasmic positivity (Chromogranin, ×100), (b) CD10 immunomarker showing negativity in the tumor cells. Also note the germinal center staining of the lymphoid follicle in the adjacent thyroid acting as internal control. (CD10, ×100), (c) EMA immunostaining showing negativity in the tumor cells (EMA, ×100).
