Summary

Description
English: Intermediate magnification micrograph of an epithelioid sarcoma, proximal subtype. Immunostain for SMARCB1 (INI1, BAF47).

This is an extremely rare tumour. It typically occurs in the extremities of young adults.[1]

Histomorphologically, these tumours can mimic carcinomas, melanomas and epithelioid angiosarcomas. They typically stain for keratins.

This tumour does not stain with an immunostain directed against SMARCB1.
