title: Primary pulmonary artery sarcoma.
abstract: Primary pulmonary artery sarcoma is an uncommon tumor. We report a case of a 73-year-old male patient with a two-week history of palpitations and shortness of breath, aggravated for two days and was believed to be pulmonary hypertension. Emergency heart ultrasound after admission presented a massive pulmonary embolism in the pulmonary artery. The patient's condition was successfully managed with urgent pulmonary artery embolectomy. The patient demonstrated improvement in hemodynamics after the operation. Histologic and immunohistochemical assays were performed and a diagnosis was made as primary pulmonary artery sarcoma arising from the left pulmonary artery. Resection of the tumor is recommended for the treatment of this rare malignant tumor. The corresponding chemotherapy, follow-up and prognosis are described as well in this case report.
