Melanon grows in stripes, starting at the site of pigment formation (here the nail root is not visible) to the front. This finding is not observed in a nail hematoma. Note: the nail matrix shows a dark discoloration at the front edge of the cut (pigment is embedded in the nail matrix).

Differential diagnosis of discoloration of the nail: Melanocytic neoplasms of the nail matrix always lead to longitudinal striation of the nail plate.
