2 year old toddler has an appointment with dermatologist for a small dark brown mole on the sole of her right foot. it appeared a couple months ago. worried that it could be serious?

It is most likely benign and an area of hyperpigmentation. Watch for signs of swelling, redness and more than one lesion. Please follow up with your Pediatrician. Sun safety includes sunscreen and a hat. Avoid sunburn since this may increase the risk for skin cancer later in life.

In this age group, most likely a small mole or "beauty mark" (think Marilyn Monroe). Skin cancer is not something we see in toddlers.
