Summary

Plasma cell granuloma, a rare condition, can present as a cardiac mass in children. This atypical case showed spontaneous regression, suggesting observation as a viable treatment option.

Area of Science:

  • Pediatric Pathology
  • Cardiovascular Surgery
  • Oncology

Background:

  • Plasma cell granuloma (PCG) typically presents as an intrapulmonary mass in children.
  • Surgical excision is the standard curative treatment for PCG.
  • Atypical presentations of PCG require consideration in differential diagnoses.

Observation:

  • An asymptomatic, unresectable cardiac mass was identified in a child.
  • The cardiac mass was diagnosed as a plasma cell granuloma.
  • The mass demonstrated significant spontaneous size reduction over 11 months.

Findings:

  • This case represents an atypical, unresectable cardiac plasma cell granuloma in a pediatric patient.
  • The cardiac mass showed a 40% spontaneous decrease in size over an 11-month observation period.

  • Complete resolution was not achieved, but significant regression occurred without intervention.

    • Implications:

    • Plasma cell granuloma should be included in the differential diagnosis for pediatric cardiac masses.
    • Observation may be a suitable management strategy for unresectable cardiac plasma cell granulomas.
    • This case highlights the potential for spontaneous regression of cardiac plasma cell granulomas, challenging traditional treatment paradigms.
