Nerve sheath myxoma (neurothekeoma)

Nerve sheath myxoma (neurothekeoma)

Agree: nerve sheath myxoma.

I will diagnose this superficial angiomyxoma, myxoid lobules (not very well defined) and containing numerous small vascular spaces and few bland spindle shaped cels.

As far as I know, nerve sheath myxoma and neurothekeoma are two different entities, I've learned it from Drs. Fetsch and Miettenen in AFIP.

Nerve sheath myxoma (neurothekeoma)

Superficial angiomyxoma

Interesting division of viewpoints. This is a superficial angiomyxoma. Neurothekeoma would be much more cellular. In this lesion, there are very few spindled cells dispersed within a very abundant myxoid background.
