On physical examination, the visible size of the black tumor on the left plantar was approximately 2 x 1 cm, with an outward expansive growth and tough texture, which cannot be pushed and does not touch the blood vessel ( Figure 1 ).
Gastroscopy revealed two 0.5 cm x 0.6 cm spots that can be seen arising from the stomach mucosa which were slightly swollen and slightly black in the center.
