Sarcomas of the large vessels usually present centrally in the aorta, pulmonary artery, and inferior vena cava. Peripheral arterial sarcomas are exceptionally rare. They have been reported in the iliac and common or profunda femoral arteries, and are frequently undifferentiated. In this study, we describe a differentiated intimal sarcoma of the superficial femoral artery with abundant osteosarcoma within the specimen. Before knowing the diagnosis, treatment was for a presumed pseudoaneurysm using excision and bypass. Postoperatively, the patient received palliative radiation therapy. The tumor's location and histopathology are unique. A differentiated intimal sarcoma has never been reported in the superficial femoral artery, and it represents the second peripheral arterial intimal sarcoma reported with osteosarcomatous differentiation.
大血管肉瘤通常位于主动脉、肺动脉和下腔静脉的中央。外周动脉肉瘤非常罕见。它们曾在髂动脉、股总或股深动脉中被报道，且通常为未分化型。在这项研究中，我们描述了一例发生于股浅动脉的分化型内膜肉瘤，其内有大量骨肉瘤。在明确诊断之前，根据疑似假性动脉瘤，采用了切除和旁路移植术进行治疗。术后，患者接受了姑息性放疗。该肿瘤的位置和组织病理学表现均很独特。分化型内膜肉瘤从未在股浅动脉中被报道过，它是第二例报道的具有骨肉瘤分化的外周动脉内膜肉瘤。
