I think melanoma on top of atypical junctional nevus ???

DD: dysplastic naevus, in situ melanoma. When does a dysplastic naevus definitively become in situ melanoma ? Other than pagetoid spread, are there any other parameters?

Severe dysplastic nevus. Pagetoid spread indicates coexisting in-situ melanoma.

Mild uniform cytological atypia (always a concern with this clincal). I could
not be sure this is a melanoma in these images. Like to see the rest of the
lesion! Some dysplastic features. Recommend complete excision!

Dysplastic naevus. While I would go upto severe based on these limited views of the architecture, I'm not convinced there is pagetoid spread.

I called this melanoma in situ arising in association with dysplastic nevus. The top two images have a different morphology as compared to the bottom three (the latter shows upward scatter as well).

I think there is enough upward spread of atypical melanocytes to make this melanoma in situ.
