Primary cardiac myxosarcoma in a child.

L J Mahar, J T Lie, R V Groover

    Mayo Clinic Proceedings
    |April 1, 1979
    PubMed
    Summary

    A rare cardiac myxosarcoma in a young child caused stroke and widespread metastases. Despite surgery and chemotherapy, the tumor led to fatal brainstem herniation.

    Area of Science:

    • Pediatric Oncology
    • Cardiovascular Pathology
    • Neuropathology

    Background:

    • Primary cardiac myxosarcoma is an exceptionally rare malignancy.
    • This case highlights the aggressive nature and potential for systemic metastasis of this tumor in children.

    Observation:

    • A 29-month-old girl presented with sudden hemiplegia and cerebral artery occlusions.
    • Echocardiography revealed a mobile left atrial tumor, surgically excised.
    • Post-operative chemotherapy included vincristine, dactinomycin, and cyclophosphamide.

    Findings:

    • Despite initial improvement, the patient experienced rapid deterioration and died 3 months post-symptom onset.
    • Autopsy confirmed brainstem herniation due to extensive tumor infiltration and widespread systemic metastases.

    Implications:

    • This case underscores the critical need for early diagnosis and aggressive management of pediatric cardiac tumors.
    • It emphasizes the potential for rapid progression and fatal outcomes, even with multimodal therapy.
    • Further research into novel therapeutic strategies for primary cardiac myxosarcoma is warranted.
