Primary pulmonary artery sarcoma masquerading as pulmonary thromboembolism: a rare diagnosis unveiled.
Background: Primary pulmonary artery sarcomas are rare malignant vascular tumors and carry a very poor prognosis. Due to overlapping clinical and radiological features, the differentiation between pulmonary artery thromboembolism and pulmonary artery sarcoma can be challenging.
Case presentation: We herein present clinical, radiological and pathological features of primary pulmonary artery high grade sarcoma (angiosarcoma) in a 59-year-old male. The patient presented with a history of breathlessness on exertion of 2-months duration and was misdiagnosed as massive pulmonary thromboembolism on initial CT imaging.
Conclusion: Great similarity with significant degree of overlap in clinical and radiologic presentation makes differentiation of pulmonary artery sarcomas and thromboembolism a diagnostic challenge. Even though they are exceptionally rare, one should always consider it as differential diagnosis especially in cases with atypical clinical or imaging presentation.
期刊介绍：
Clinical Sarcoma Research considers for publication articles related to research on sarcomas, including both soft tissue and bone. The journal publishes original articles and review articles on the diagnosis and treatment of sarcomas along with new insights in sarcoma research, which may be of immediate or future interest for diagnosis and treatment. The journal also considers negative results, especially those from studies on new agents, as it is vital for the medical community to learn whether new agents have been proven effective or ineffective within subtypes of sarcomas. The journal also aims to offer a forum for active discussion on topics of major interest for the sarcoma community, which may be related to both research results and methodological topics.
