From: Epithelioid sarcoma is associated with a high percentage of SMARCB1 deletions
Examples of epithelioid sarcomas: classical epithelioid sarcoma showing (a) intersecting hyalinized collagen (hematoxylin and eosin, × 40) and (b) negative SMARCB1 staining in tumor cells with positive infiltrating lymphocytes ( × 40). Proximal epithelioid sarcoma showing (c) confluent growth of large epithelioid cells with prominent nucleoli (hematoxylin and eosin, × 40) and (d) negative SMARCB1 staining in tumor cells with positive background endothelial cells ( × 40). Proximal epithelioid sarcoma showing (e) pleomorphic cells with a mixed spindle and epithelioid morphology (hematoxylin and eosin, × 40) and (f) retained SMARCB1 expression ( × 40).
