Rare cardiac epithelioid hemangioendothelioma demands thorough imaging and pathology workupRare Vascular Tumor Can Affect Multiple Organs at Once

This publication is a case report combined with a literature review focused on epithelioid hemangioendothelioma (EHE), a rare low-grade malignant vascular neoplasm with local aggressiveness and metastatic potential. The report describes a single patient with right atrial EHE and multi-system involvement.

The authors note that EHE may involve multiple anatomical sites, including the lungs, liver, bones, and soft tissues, either synchronously or metachronously. This pattern underscores the need for comprehensive evaluation when the diagnosis is suspected.

The stated practice relevance is that thorough diagnostic evaluation, including pathological and imaging modalities, is necessary for accurate characterization of EHE. No intervention, comparator, or primary outcome was reported, and no safety or adverse event data were provided.

The authors acknowledge a small sample size (single case report) as a limitation. Funding sources and conflicts of interest were not reported. Because this is a case report and literature review rather than a clinical trial, the findings cannot establish causality or support broad treatment recommendations. Clinicians should interpret the diagnostic considerations in the context of the limited evidence base.
