Moles are caused when cells in the skin, called melanocytes, grow in clusters or clumps. Melanocytes are distributed throughout your skin and produce melanin, the natural pigment that gives your skin its color.
These moles are unusual and even more unlikely if you have ordinary moles on other parts of your body. Like skin tags, moles rarely become infected, ulcerated or cancerous. But, as I hope you already know, a certain type of mole called a melanoma is cancerous and can spread and cause death. In any event, I suggest, at least the first time, that you have any such skin growth looked at by a doctor.
