Cardiac Fibroma with Ventricular Tachycardia: An Unusual Clinical Presentation of Nevoid Basal Cell Carcinoma Syndrome

Abstract

Pediatric cardiac tumors are rare and often benign with an incidence of approximately 0.03-0.32% and can be associated with genetic conditions. For example, approximately 3% of individuals with nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, have a cardiac fibroma. NBCCS is also characterized by lamellar or early calcification of the falx, jaw keratocysts, palmar and/or plantar pits, and a predisposition for basal cell carcinomas. Given the management implications of NBCCS, including appropriate cancer screenings and precautions, prompt identification of affected individuals is critical. We report a case of a 6-year-old female presenting with ventricular tachycardia secondary to cardiac fibroma. After diagnosis of recurrent jaw keratocysts, she was clinically and molecularly diagnosed with NBCCS. Identification of a cardiac fibroma should prompt careful assessment of past medical and family history with consideration of a diagnosis of NBCCS.
