Primary Pulmonary Vein Leiomyosarcoma With Left Atrial Extension

Area of Science:

• Cardiovascular Surgery
• Surgical Oncology
• Pathology

Background:

• Leiomyosarcoma (LMS) is a rare mesenchymal tumor arising from smooth muscle.
• LMS commonly affects the great vessels, particularly the inferior vena cava.
• Pulmonary vein LMS is an exceptionally rare presentation.

Observation:

• A case of pulmonary vein LMS invading the left atrium is presented.
• This tumor is aggressive and requires surgical intervention.
• The tumor was successfully resected.

Findings:

• The successful resection of a pulmonary vein LMS extending into the left atrium.
• Demonstrates the feasibility of surgical management for this rare tumor.
• Highlights the importance of considering rare tumor locations in differential diagnoses.

Implications:

• This case expands the understanding of LMS presentation and surgical possibilities.
• Contributes to the limited literature on pulmonary vein LMS.
• Informs surgical strategies for rare cardiovascular tumors.
