Hello, i have a cut in between my pinky toe, its bigger than a paper cut and probably a little more than a quarter inch deep. what could it be?

Fissure: Which is a crack in skin. Can be from athletes foot or simple dry skin. See ur podiatrist for treatment.

Fissure: If you do not have a history of trauma where you could have cut your toe, then you probably have a fissure. Athletes foot and dry skin can cause fissures between and under the toes. Your podiatrist can prescribe medication that will treat this problem.
