Infantile pericardial round cell tumor

Area of Science:

• Pediatric Oncology
• Cardiovascular Pathology
• Rare Cancers

Background:

• Cardiac malignancies are exceptionally rare in infants.
• Desmoplastic Small Round Cell Tumor (DSRCT) is an aggressive malignancy typically affecting the abdomen.
• Infantile DSRCT is exceedingly uncommon, with limited case reports.

Observation:

• This report details a unique case of DSRCT occurring within the pericardial sac of an infant.
• The tumor presented as an intrapericardial mass, a location previously undocumented for DSRCT in this age demographic.
• Diagnostic challenges included differentiating the cardiac mass from other pediatric tumors.

Findings:

• Histopathological examination confirmed the diagnosis of Desmoplastic Small Round Cell Tumor.
• The intrapericardial location represents a novel anatomical site for DSRCT in infants.
• Molecular and genetic analyses are pending to understand potential unique characteristics.

Implications:

• This case expands the known spectrum of anatomical locations for DSRCT in infants.
• Highlights the importance of considering rare malignancies in the differential diagnosis of infant cardiac masses.
• May prompt further investigation into the potential for DSRCT to arise in diverse pediatric locations.
