Black Dot Appeared After Mole Removal
- Asked by Grad Student in NY in Central NJ

About a month ago a dermatologist removed a colorless raised mole from my back, with a scalpel, when I requested. The mole was benign. Now a flat black dot has appeared where the mole was. The area has not been exposed to the sun and other than the dot it appears to be healing well. What could cause the appearance of pigmentation where none has ever been and is this something I should go get checked out?

An small, central area of hyperpigmentation is common after a shave excision. This is because the mole is actually "shaved off" at a level just below the surface of the skin. If the biopsy results show it to be cancerous or pre-cancerous then a second step, a complete excision with uninvolved margins, is necessary to ensure its complete removal. The mole will rarely regrow and the appearance with the central dark spot should not be objectionable. If the black dot grows larger in the future, please use the ABCDE's as your guide for when to be concerned: Asymmetry; Irregular Borders; black or uneven Colors; Diameter greater than a pencil eraser; and a growth that is Evolving or changing.

This is likely a recurrence of the mole. If it was removed with a scalpel, the question is how it was done. Was the mole shaved off or excised by cutting it out? If it was shaved the recurrence is very high, almost guaranteed. The recurrence can even occur with excision. It depends on how much of a margin you take with the mole sometimes as well. If you the margins are 3 mm the recurrence is low teens, 4mm high single digits, 5mm lower single digits, percentage wise. Below is a video to illustate our answer better.

Pigment Appears After Mole Removal
The good news is that the lab test showed the mole was benign. That being the case you don't need to do anything. Over the next year you should expect the darkness to fade naturally.
What may have caused this to happen? Even flesh colored moles have pigment cells. When the top is removed the root of the mole below is triggered to try to re-grow another mole. Since it can't, the pigment production is the best it can do.
