Why the study?
Pulmonary artery angiosarcoma is an extremely rare and aggressive malignancy with poor prognosis and few reported cases, making early diagnosis critical.
Pulmonary artery angiosarcoma is a rare, aggressive malignancy that can mimic chronic thromboembolic pulmonary hypertension and requires early diagnosis.
Alerts clinicians to consider angiosarcoma in CTEPH differentials; leaves open optimal diagnostic strategies pending larger studies.
Pulmonary artery angiosarcoma (PAA) is an extremely rare malignancy that arises from endothelial cells. The pulmonary trunk is the most common anatomic site of these tumors. However, so far, there have only been a few examples of PAA reported. PAAs are aggressive and have a bad prognosis, thus early diagnosis is critical. In this study, we present the case of a 27-year-old male who was initially diagnosed with acute pulmonary thromboembolism (PTE) before being diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH). Pulmonary endarterectomy was performed, and PAA was diagnosed histopathologically. The patient died three months after diagnosis.
