Summary
Primary Pulmonary Artery Sarcoma mimics Thromboembolic Pulmonary Disease, complicating diagnosis. This case highlights the importance of considering rare sarcomas in patients with suspected pulmonary vascular conditions.
Area of Science:
- Cardiovascular Medicine
- Oncology
- Pathology
Background:
- Primary Pulmonary Artery Sarcoma (PPAS) is a rare malignancy.
- PPAS shares clinical and imaging features with Thromboembolic Pulmonary Disease (TEPD), posing diagnostic challenges.
Observation:
- A 59-year-old male presented with dyspnea, chest pain, and constitutional symptoms.
- Initial investigations including imaging suggested TEPD, supported by positive Lupus Anticoagulant and Ig M Anticardiolipin tests, indicating a hypercoagulable state.
- Despite anticoagulation, the patient experienced clinical and radiological deterioration.
Findings:
- The patient underwent a right pneumonectomy due to bleeding during attempted Pulmonary Thromboendarterectomy.
- Post-surgery, the patient developed ARDS and died on the 7th postoperative day.
- Histopathological examination confirmed Primary Pulmonary Artery Sarcoma with pulmonary and pleural metastases.
Implications:
- This case underscores the critical need for a high index of suspicion for rare tumors like PPAS in the differential diagnosis of TEPD.
- Accurate and timely diagnosis is crucial for appropriate management and potentially improved patient outcomes.
- Advanced imaging and biopsy may be necessary to differentiate PPAS from TEPD when clinical suspicion is high.
