Panelists discuss how a real-world case of epithelioid sarcoma (ES) highlights the critical role of early recognition, comprehensive diagnostics including INI1 testing, and a multidisciplinary approach to personalize treatment based on disease extent, tumor location, and molecular features.

Summary for Physicians: Case-Based Discussion in ES

A patient case was presented to illustrate the complexities of diagnosing and managing ES. The case highlighted the importance of early recognition, thorough diagnostic workup—including imaging and histopathologic evaluation—and the role of molecular testing (eg, INI1 loss) in confirming the diagnosis.

Initial impressions from the group emphasized the diagnostic challenges, particularly when ES mimics benign or inflammatory conditions. Participants noted the importance of maintaining a broad differential in atypical soft tissue masses and the utility of early biopsy and referral to a specialized sarcoma center.

In terms of treatment, discussion focused on tailoring the approach based on disease extent, tumor location, patient status, and molecular characteristics. Surgery was considered central for localized disease, while systemic therapy was emphasized in cases with advanced or metastatic features. The case underscored the need for a multidisciplinary strategy and highlighted how evolving molecular insights may guide more personalized treatment decisions in clinical practice.
