The Masson-Fontana silver method for melanin resulted positive and the pigments manifested a strong argentaffin reaction. In the extracellular space, pigment granules were abundant and dispersed throughout the parenchyma (Figure 2).

A strong argentaffin reaction is exhibited in pigmented cells (arrowheads) and in extracellular space.

In the argentaffin reaction (modified Masson-Fontana technique), a reduction in the ammoniacal silver nitrate is a result of the reducing capacity of its cellular components (RODRIGUES et al., 2005).
