Key result
Surgical excision reveals a rare cartilaginous left atrial myxoma presenting as mitral stenosis.
Why the study?
Primary cardiac tumors are extremely rare, and this case is presented for its clinical, imaging, and uncommon histological features of cartilaginous differentiation.
Case Report (n=1)
This case highlights an uncommon histological variant of cardiac myxoma with cartilaginous differentiation presenting clinically as mitral stenosis.
Alerts clinicians to myxoma in young adults with obstructive symptoms; leaves open need for larger registries on rare cardiac tumors.
The estimated incidence of primary cardiac tumors is extremely rare. Among it, cardiac myxoma represents the most common benign cardiac tumor constituting about 80% of cases. We are presenting a 30-year-old female with large left atrial myxoma. She was presented with severe dyspnea, palpitations, and systolic murmurs. On 2D echocardiography, left atrial mass obstructing mitral flow was noted. On cardiac magnetic resonance imaging, a single, large, mobile pedunculated mass lesion in left atrium attached to inferior interatrial septum with heterogeneous enhancement was noted, which was likely represented to be myxoma. The mass was surgically excised and valve repairing was done. We received large, solid, lobulated, gray white, soft-to-firm mass measuring 4.5 × 4.1 × 2.5 cm, and on microscopy showed cardiac myxoma with cartilaginous differentiation. We are presenting this case for its clinical, imaging, and uncommon histological features.

Jagtap et al. (2019) conducted a case report in Cardiac myxoma with cartilaginous differentiation (n=1). Surgical excision and valve repair was evaluated on Histological diagnosis and clinical presentation. Surgical excision of a large left atrial mass in a 30-year-old female revealed a rare cardiac myxoma with cartilaginous differentiation presenting as mitral stenosis.
