Cardiac rhabdomyoma: a clinicopathologic study
1Department of Cardiovascular Pathology, Armed Forces Institute of Pathology, Washington, DC.
Summary
Cardiac rhabdomyomas, tumors of the heart, can occur sporadically or with tuberous sclerosis. Surgical resection may be successful for these early-presenting tumors.
Area of Science:
- Cardiovascular Pathology
- Pediatric Oncology
Background:
- Cardiac rhabdomyomas are the most common primary heart tumors in infants and children.
- These tumors can present with significant morbidity and mortality due to obstruction or arrhythmias.
Purpose of the Study:
- To investigate the clinical and pathological characteristics of cardiac rhabdomyomas.
- To determine the association of cardiac rhabdomyomas with genetic syndromes and other cardiac malformations.
- To evaluate the outcomes of surgical intervention for cardiac rhabdomyomas.
Main Methods:
- Retrospective review of 17 cardiac rhabdomyomas from 13 males and 4 females.
- Analysis of clinical presentations, including congenital heart disease and tuberous sclerosis.
- Immunohistochemical analysis of tumor markers (myoglobin, actin, desmin, vimentin, S-100 protein).
Main Results:
- Tumors occurred in patients from birth to 9 years, with 11 cases being multiple.
- Four patients had congenital heart disease; three had tuberous sclerosis.
- Sudden cardiac death occurred in two patients; three of four surgically resected tumors had successful outcomes.
Conclusions:
- Cardiac rhabdomyomas can be sporadic, associated with tuberous sclerosis, or linked to other cardiac malformations.
- Presentation is typically early in life with varied symptoms, including sudden death.
- Surgical resection can be a viable treatment option with potential for successful outcomes.
