Primary intracardiac germ cell tumor

Area of Science:

• Pediatric Oncology
• Cardiovascular Imaging
• Germ Cell Tumors

Background:

• Intracardiac germ cell tumors are rare pediatric malignancies.
• Metastatic presentation of these tumors is uncommon, especially to extrathoracic sites like the scalp.

Purpose of the Study:

• To report a unique case of a 6-year-old girl with scalp swelling due to metastases from an intracardiac germ cell tumor.
• To illustrate the role of echocardiography in diagnosing primary cardiac tumors and their metastatic spread.

Main Methods:

• Case presentation of a pediatric patient with a history of scalp swelling.
• Diagnostic imaging including echocardiography to evaluate the heart and identify the primary tumor.
• Histopathological confirmation of metastatic germ cell tumor in the scalp.

Main Results:

• Echocardiography identified an intracardiac mass, consistent with a primary germ cell tumor.
• Scalp swelling was confirmed as metastatic disease originating from the intracardiac tumor.
• The patient's clinical presentation and diagnostic findings represent a rare metastatic pattern.

Conclusions:

• This case underscores the importance of considering rare metastatic sites for intracardiac germ cell tumors.
• Echocardiography is crucial for the initial diagnosis and characterization of primary cardiac tumors in children.
• Early detection and diagnosis are vital for managing rare pediatric malignancies with extrathoracic metastases.
