    A rare case of pediatric heart lymphosarcoma mimicked pericarditis, showing temporary improvement with prednisolone. Post-mortem analysis revealed mediastinal lymphosarcoma invading the heart, highlighting the importance of cytologic examination in unexplained pericardial effusions.

    Area of Science:

    • Pediatric oncology
    • Cardiovascular pathology
    • Hematologic malignancies

    Background:

    • Lymphosarcoma, a type of non-Hodgkin lymphoma, can rarely affect the heart in children.
    • Distinguishing cardiac tumors from inflammatory conditions like pericarditis can be diagnostically challenging.

    Observation:

    • A 10-year-old boy presented with symptoms suggestive of pericarditis.
    • Initial treatment with prednisolone resulted in a temporary clinical improvement.
    • Post-mortem examination was crucial for definitive diagnosis.

    Findings:

    • The autopsy revealed a highly differentiated lymphosarcoma originating from the mediastinum.
    • The tumor extensively infiltrated the pericardium and myocardium.
    • Malignant cells were identified in the pericardial fluid.

    Implications:

    • This case underscores the importance of considering rare malignancies in pediatric cardiac conditions.
    • Cytologic examination of pericardial fluid is a critical diagnostic tool for unexplained effusions.
    • Early recognition and diagnosis of cardiac lymphosarcoma are vital for potential therapeutic interventions.
