Case Report: Metastatic squamous cell carcinoma in the left atrium

Area of Science:

• Cardiology
• Oncology
• Pathology

Background:

• Cardiac metastases are the most frequent malignant cardiac tumors, characterized by rapid progression and poor prognosis.
• Current treatment options for cardiac metastases are limited, highlighting significant diagnostic and therapeutic challenges.

Observation:

• A 52-year-old female presented with exertional palpitations and worsening cough, exhibiting a left atrial mass on echocardiography.
• Surgical excision of the mass revealed metastatic squamous cell carcinoma.

Findings:

• Intracardiac metastasis is exceptionally rare, often presenting with subtle, non-specific symptoms that can delay diagnosis.
• Definitive diagnosis of cardiac metastasis necessitates pathological examination following initial imaging studies.

Implications:

• Timely diagnosis of intracardiac metastasis is critical for effective management and improved patient prognosis.
• This case underscores the importance of considering metastatic disease in cardiac masses, even with non-specific symptoms.
