    A rare intracardiac epithelial heterotopia, a tumor with glandular structures, was found in an infant. This unusual heart tumor caused superior vena cava obstruction, leading to early death.

    Area of Science:

    • Cardiovascular Pathology
    • Developmental Biology
    • Pediatric Oncology

    Background:

    • Intracardiac tumors are rare in infants, with varied origins and clinical presentations.
    • Epithelial heterotopias typically occur in other organs, rarely presenting within the heart.
    • Understanding the developmental origins of cardiac anomalies is crucial for diagnosis.

    Observation:

    • A case of intracardiac epithelial heterotopia with a significant mesenchymal component is presented.
    • The lesion microscopically mimicked a cardiac myxoma but was distinguished by unique glandular structures.
    • The tumor demonstrated aggressive myxoid component invasiveness.

    Findings:

    • The heterotopic cardiac tumor caused superior vena cava (SVC) occlusion.

  • Clinical symptoms manifested early in infancy due to the SVC syndrome.
  • The patient, a 6-month-old infant, succumbed to the invasive cardiac lesion.

    • Implications:

    • This case highlights a rare differential diagnosis for pediatric cardiac masses.
    • The findings suggest aberrant primitive cell differentiation as a potential etiology for cardiac heterotopias.
    • Early detection and understanding of such rare tumors are vital for potential therapeutic strategies.
