I had a biopsy of a mole taken earlier this week and now there is a black/dark brown spot in the wound. Could this be because the doctor didn't get all of the nevus cells or could it be skin cancer that has a deeper breslow depth that was shaven off?

Answer: Dark spot in mole biopsy wound
You most likely had a shave biopsy of your mole which typically leaves a minimal scar and sometimes will heal with a central area of hyperpigmentation. The mole will rarely regrow and the appearance with the central dark spot should not be objectionable. 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.
