Pulmonary leiomyosarcoma presenting as a pancoast tumor

Area of Science:

• Oncology
• Thoracic Surgery

Background:

• Pancoast tumors are apical lung malignancies often associated with non-small cell lung cancer.
• Leiomyosarcoma is a rare soft tissue sarcoma that can occur in the lung.

Observation:

• A patient presented with Pancoast syndrome, a clinical manifestation of an apical lung tumor.
• The patient was diagnosed with pulmonary leiomyosarcoma, a rare form of lung sarcoma.

Findings:

• The patient underwent a right upper lobectomy and chest wall resection, including ribs 1-3.
• Rapid local and distant recurrence of the pulmonary leiomyosarcoma was observed post-surgery.
• No prior literature documented pulmonary sarcoma presenting as a Pancoast tumor.

Implications:

• Pulmonary leiomyosarcoma should be considered in the differential diagnosis of Pancoast tumors.
• Early detection and prompt surgical intervention are vital for managing this rare and aggressive lung malignancy.
• Further research into the characteristics and treatment of pulmonary leiomyosarcoma is warranted.
