Do I need to have another excision after an atypia mole was removed for biopsy?
I am 34, female. I had a mole on my lower leg shaved and sent for biopsy. The pathology result was "moderate atypica" but it also stated "biopsy margins negative." Why do I need to go back to have more skin removed with stitches? This is the third atypia mole I've had. I would like to know other opinions on whether or not I need to go back for another excision this time and why. Thanks.

For moderately atypical moles, a 2mm margin is generally preferred. If the physician feels adequate margins were not obtained with the biopsy, the physician will re-excise with 2mm margins. Some physicians will monitor area for recurrence if the margins are clear with biopsy.
The degree of atypia in a mole is determined by the pathologist and not the clinical appearance of the mole by itself. If the pathologist examines the mole and determines that the degree of atypia is moderately atypical, it is typically recommended to have a margin of normal tissue removed or a re-shave of the area. Please use a board certified dermatologist for the best results.
