The bulge of the lip in the lower right corner of the picture is caused by a melanoma.
Upon opening the mouth a dark spherical mass was found at the level of the gingiva.
The mass does not always have to be dark to be a melanoma. In the above dog, the mass at the height of the upper lip is flesh-coloured, but the sampling confirmed that it was a tumour of the pigment cells.
