原发部位骨肉瘤

定义

一种通常具有侵袭性的恶性骨形成间质瘤，主要影响青少年和年轻人。通常涉及骨骼，较少涉及骨外部位。它常常累及长骨（尤其是股骨远端、胫骨近端和肱骨近端）。疼痛伴或不伴可触及肿块是最常见的临床症状。它可能扩散到其他解剖学部位，特别是肺部。

A usually aggressive malignant bone-forming mesenchymal tumour, predominantly affecting adolescents and young adults. It usually involves bones and less frequently extraosseous sites. It often involves the long bones (particularly distal femur, proximal tibia, and proximal humerus). Pain with or without a palpable mass is the most frequent clinical symptom. It may spread to other anatomic sites, particularly the lungs.
