骨軟部&整形外科領域放射線(画像)診断学において、「Skeletal Radiology」誌がとても役立ちますよ、ということを以前お話ししましたが、最新号の「Volume 50, issue 7, July 2021」から下記2論文を紹介します。

An update on imaging of Paget’s sarcoma. (Skeletal Radiology 2021;50(7):1275–1290.)
Paget病から生じる肉腫の総説です。有名ですけど、ほとんど経験したことはな いです。

Imaging of bone and soft tissue BCOR-rearranged sarcoma. (Skeletal Radiology 2021;50(7):1291–1301.)
最近、肉腫の名称も遺伝子的に細分化されています。
Ewing肉腫は EWSR1/FUS-ETS 融合を有する遺伝子的に狭く定義されています。
非典型的な遺伝子異常や形質を示す小円形細胞肉腫(いわゆるEwing様肉腫)に 関しては,① EWSR1-nonETS 融合遺伝子を有する肉腫,② CIC 肉腫,③ BCOR 関連 肉腫の3つに大きく区別されています。

With recent advances in molecular research, an ever-increasing number of undifferentiated round cell sarcomas without the characteristic gene fusions of Ewing sarcoma are being discovered. One specific subtype termed BCOR-rearranged sarcoma belongs to this group. Previously termed ‘Ewing-like’ sarcoma, it was formally included with undifferentiated round cell tumours in the 2013 WHO Classification of Soft Tissue and Bone Tumours. However, in the 2020 WHO Classification, BCOR-sarcoma is now recognized as a distinct entity due to particular morphological and immunohistochemical features and differing clinical outcomes. As with classical Ewing sarcoma, osseous BCOR-rearranged sarcoma is an aggressive tumour with a similar clinical presentation.
