Recent shave mole biosopy.. with the healing the edges of the site are brown? not the middele, and the pathology test came back saying it was a atypical benign mole. Should I be concerned?

Removal of Atypical Moles
In my office, I will do an excision with suture closure to get clear margins for all moles that have "moderate to severe atypia". For a mildly atypical mole I will observe the area and if any pigmentation remains or recurs in the biopsy site it is excised. Since you may still have some pigment-making cells still present around the previous biopsy site you should have the area re-examined by your dermatologist and consider having the area excised. We also follow all of our "atypical mole" patients by doing full skin examinations every six months.
Shave excision of moles
Shave excision or shaving off a mole is less likely to remove a mole completely compared to a formal surgical excision, as with shave excision the tissue deep within the thickness of skin is not removed. This is the part that quite often will contain the pigment cells. This is likely to be reason you have brown edges to the scar. As long as the histopathology showed the mole to be benign (that is no sign of any cancer) I would not worry.
Shaved moles often leave undesireable scars on the face.
Shaved moles often leave undesireable scars on the face. I would recommend a careful reexcision of the moles with sutures. Ultimately you will get a much better cosmetic result.

Ensure Adequate Margins
Hello, when a biopsy is performed pathology can inform the doctor of the type of lesion and give information regarding the margins (whether a rim of adequate normal tissue was removed around the lesion). Different lesions need different amounts of margin to help ensure their removal. Cancerous lesions need the most, while lesions with atypia require adequate margins but usually need less. If your biopsy site has dark edges, it may be part of the healing process, but could be residual mole at the skin edges. If the pathology showed some atypia I would recommend showing this to your doctor and to ensure you do not need additional margins taken via a re-excision. Leaving residual cells from this mole can increase your risk for recurrence or progression of the atypia to a more serious lesion.
