Key result
Cardiac sarcoma excision resolves hypereosinophilia in a pediatric patient who died ~3 months later.
Why the study?
Cardiac malignancies with hypereosinophilia in children are extremely rare and their clinical implications are not well understood.
Case Report (n=1)
This case report highlights a potential relationship between cardiac malignancy and hypereosinophilia, as surgical removal of the tumor resolved the persistent hypereosinophilia.
Single-case resolution after sarcoma excision suggests paraneoplastic hypereosinophilia; leaves open survival impact and requires confirmation before diagnostic consideration.
Cardiac malignancies in children are extremely rare and they with hypereosinophilia are rather relatively uncommon. The majority of individuals may survive over the long term even with heart tumors provided they don't have any significant symptoms and their hemodynamics are unaffected. But we should nevertheless be aware of them, especially when they are coupled with persistent hypereosinophilia and the development of a hemodynamic anomaly. The case of a malignant heart tumor with hypereosinophilia in a 13-year-old girl is presented in this paper. She exhibited an echocardiographic deficit and a heart murmur. Additionally, it was difficult to treat her hypereosinophilia. Nevertheless, it was resolved the day after the operation. We presume that there is a certain relationship between them. This study gives clinicians a wide range of options for analyzing the connections between malignancy and hypereosinophilia.

Zhang et al. (2023) conducted a case report in Cardiac endothelial sarcoma with hypereosinophilia (n=1). Surgical excision of intracardiac tumor and mitral valve replacement was evaluated on Resolution of hypereosinophilia and survival. Surgical excision of a malignant cardiac endothelial sarcoma in a 13-year-old girl led to the immediate resolution of her persistent hypereosinophilia, though she died 3 months later.
