Looks like a special sites nevus. There's atypia, but not out of the norm for nevi of the breast/milk-line. No pagetoid spread, no dermal mitoses. If it's out there's no need for additional excision. If it goes to a margin I'd recommend conservative complete removal.

I know the dermpathpro team posted my opinion inadvertantly at the beginning of the day in the history but I would really hope to get a few more comments on the case (in any case you may not agree with my opinion). I suspect there are many of you who check on cases but never post a suggestion - now is your opportunity to contribute! I will leave it open and sincerely hope you enjoy your weekends.

I didn’t read Dr. Carr’s diagnosis that was posted early, so I write my opinion blindly.
It´s a [url="http://onlinelibrary.wiley.com/doi/10.1111/j.0303-6987.2004.00159.x/abstract"]site-specific nevus from breast[/url]. Junctional melanocytic nests that are large, horizontally-oriented and coalescent may cause concern, and melanoma or [url="https://dermpathpro.com/blog/3/entry-126-dysplastic-nevus-as-a-legitimate-phrase/"]so-called “dysplastic nevus”[/url] may therefore be signed out. However, these findings are indicative of site-specific nevus within the overall context of a symmetric lesion that begins and ends with a nest, melanocytes that are bland and monomorphic, and a case history of a pigmented lesion on a breast of a young woman.

Agree with all the considerations above. Irregularly shaped and spaced nests, focal epidermal consumption, mild nuclear atypia, and dust-like pigment although generically indicating "dysplasia" are pretty much consistent with a special site nevus, given the clinical context

Yes I also reported this as a special site naevus. She had two similar lesions excised at the same time.
