Great case from Dr Uma Sundram to get you off to a good day.

Geoff Cross - DermpathPRO Projects

Superficial variant of DPN

I would have probably called it nevus with halo like reaction, I am 100% sure this lesion is benign.

Halo phenomenon.

Considering the clinical presentation of a pigmented lesion, and the microscopic picture of scattered nests of nevus cells with regressive changes embedded in a dense inflammatory infiltrate, I tend to melanocytic nevus with halo phenomenon, or halo nevus without halo.

In my daily practice I would call this lesion a common nevus with halo phenomenon as well.

Agree with halo phenomenon/halo nevus

Dermal spitz nevus with regresion (halo fenomenon)

Dermal naevus with a halo phenomenon. 

Regressing Spitz/PSCN

I don't see any papillary dermal component, as expected in DPN..., but I comprise there is too halo-regressing changes that confuse the backdrop... 

Excellent. We called it a Spitz nevus with halo phenomenon and recommended a re excision.
