Amelanotic desmoplastic blue nevus

My impression was hypopigmented blue nevus, according to Mckee's book this entity is in the same spectrum (or is actually the same entity) of desmoplastic blue nevus. Personally, I like to see more abudant sclerotic broad collagen to call it desmoplastic, but I think this is a matter of taste.

I think this is a combined naevus sclerosing and blue.

Wow, I did not think this was controversial at all :)

Agree with all of your comments. I favored hypopigmented blue nevus. Combined nevus would work as well.

Agree with hypopigmented blue naevus.  Usually S100 negative, melanA positive as opposed to a naevocellular naevus with is S100 positive.
