Question on odd moles

I am hoping someone can shed some light on moles, atypical moles and melanoma.   I always thought my moles were normal.   I have a bunch of very dark ones that are all flat.  Some of them are so dark brown they appear black at times.   I had my first mole check in the summer.   The dermatologist made a comment on my funny moles and removed a small one from my back.   This mole came back with mild atypical.   I was told to come back every 6 months.   I went to a new dermatologist that was closer to my house.   He did not bring up my moles at all except when he said the good thing about having a good deal of moles is that it makes it easy for me to see how your moles are supposed to look.    That visit was in Dec and he told me to have my wife check my moles every month and keep an eye for any changes.   He wanted to see me back in two years.

I had a seperate emergency and needed to see a dermatologist asap.  I had an allergic reaction to something.  I went to another dermatologist last week.   While examining my rash he commented on my moles.   He then asked if I wanted a body exam.   He removed a mole from my chest which I have had my entire life. He said that looked atypical.

Today I was examining my moles and realized almost none of them are perfectly round.  They all have variying shades of brown so they are not all the same color.   I then noticed one on my love handle that looks like the rest of my moles dark brown but it has 4 distinct dark brown spots ( almost looks like 4 pin head spots visible in the mole When I Spread the skin apart these 4 dark spots are visible. .    My question is how concerned should I bewitht this ?  Considering two derms have examined me in a month ?  Should I go back and show this odd looking mole to the dermatologist again?  Also because most of my moles look the same are not perfectly round do I have dyaplastic nevus syndrome or are these normal tiny moles and thats just the way they appear on my body ?
