I don't know what they mean by 'abnormal.' I suspect they mean that the moles were read as 'atypical' under the microscope, but many moles are a little atypical without their meaning much of anything. If they were very atypical, the pathologist would have recommended that extra tissue be removed as a margin of safety, but that doesn't seem to have been judged as necessary. So I think that you don't need to think about these moles at all, just return for regular checks as recommended by your dermatologist. I do, however, think you deserve to get a fuller explanation from the dermatologist about what 'abnormal' means (or doesn't mean) in connection with your moles.
Take care.
