Q: Can a mole become dangerous after shave biopsy on upper arm ?

asked by: DoctorQuestion on August 31st, 2007

I recently had a shave biopsy done on a mysterious looking mole on my upper arm. The results came back that it was a normal mole. However, I am concerned because the mole has come back now and looks strange. It is the all the same dark color, but with very jagged edges. The biopsy came back as a normal mole, could it have changed to something dangerous since then? The biopsy was done about 2 1/2 months ago. When I talked to the dermatologist at that time she said that I didn't need to come back for 1 1/2 to 2 years.

“Jagged edges” around a mole is not an accurate sign of eventual malignant transformation of the mole (nevus). Signs of malignant transformation include: color change, pain, edema, growth, redness around the mole etc. You must consult a plastic surgeon about further treatment. for example, it is possible to remove the mole even if it is benign just to ease your mind.
