This could be caused by irritation from a pest (tick), a dermatologic condition (oily skin) or even dry skin. This probably isn't serious if isolated and not persistent.

The differential is so broad without more info. Most commonly it would be something benign like a callus or a cyst related to trauma. Of course there are more worrisome causes like cancer or lymphoma. Go to your local vet to have them look at it to get a definite answer.
