Cardiac papilloma. A case report with evidence of thrombotic origin
Archives of Pathology & Laboratory Medicine
|May 1, 1983
Abstract:
A pulmonic valve cardiac papilloma was found in a patient with coagulopathy and disturbed right ventricular hemodynamics. Fibrin was demonstrated within the cores of the papillae, lending further support to the thrombotic derivation of these lesions. The tumor's papillary configuration was thought to be the result of molding by the turbulent blood flow at that site.
Insights
A cardiac papilloma was identified in the pulmonic valve of a patient with bleeding disorders and abnormal right ventricular blood flow. Fibrin within the papillae suggests a thrombotic origin for this cardiac tumor.
Area of Science:
- Cardiovascular Pathology
- Cardiac Oncology
- Hemodynamics
Background:
- Cardiac tumors are rare, with papillary lesions of the heart valves presenting unique diagnostic challenges.
- Understanding the etiology of cardiac tumors is crucial for diagnosis and treatment planning.
Observation:
- A case study identified a pulmonic valve cardiac papilloma in a patient presenting with coagulopathy.
- The patient also exhibited disturbed right ventricular hemodynamics, indicating impaired cardiac function.
Findings:
- Histopathological examination revealed fibrin within the core of the papillary lesion.
- This finding supports the hypothesis that the cardiac papilloma originated from a thrombus (thrombotic derivation).
- The papillary morphology is attributed to the molding effect of turbulent blood flow within the right ventricle.
Implications:
- This case highlights the potential thrombotic origin of cardiac valve papillomas, particularly in patients with bleeding disorders.
- The findings underscore the importance of considering hemodynamic factors in the development of cardiac lesions.
- Further research into the pathogenesis of cardiac valve tumors is warranted to improve patient outcomes.
