Atrial myxoma associated with multiple hamartomas

H Kaneko, T Murohashi, A Katano

    Acta Pathologica Japonica
    |September 1, 1976
    PubMed
    Summary

    This case report details a rare cardiac myxoma combined with multiple renal hamartomas and thyroid adenoma. The findings suggest potential links to genetic syndromes and support the hamartoma theory for cardiac myxoma development.

    Area of Science:

    • Cardiovascular Pathology
    • Neoplastic Syndromes
    • Gastrointestinal Oncology

    Background:

    • Cardiac myxomas are rare primary heart tumors, often associated with genetic syndromes.
    • Renal hamartomas encompass a spectrum of benign renal tumors, including angiofibrolipomas and fibromas.
    • The co-occurrence of multiple benign neoplasms warrants investigation into underlying genetic predispositions.

    Observation:

    • A unique case presenting cardiac myxoma alongside renal angiofibrolipomas, renal medullary fibromas, thyroid adenoma, and a jejunal polyp.
    • The combined presentation of cardiac myxoma and renal hamartoma is unprecedented in existing literature.
    • Significant atypia was observed in the cardiac myxoma, renal angiofibrolipomas, and thyroid adenoma.

    Findings:

    • The constellation of findings suggests a potential link to genetic disorders such as tuberous sclerosis, Cowden disease, or lymphangiomatosis.
    • The histogenesis of the cardiac myxoma in this case aligns with the hamartoma theory.
    • The simultaneous atypism across multiple neoplastic lesions highlights complex pathogenetic mechanisms.

    Implications:

    • This case expands the known spectrum of tumors associated with certain genetic syndromes.
    • Further research into the shared etiology of cardiac and renal hamartomas is indicated.
    • Understanding these complex associations can improve diagnostic and therapeutic strategies for patients with multiple neoplasms.
