Extraskeletal Ewing's sarcoma (EES) is a rare, soft tissue, malignant neoplasm histologically similar to skeletal Ewing's sarcoma. It occurs mainly in adolescents and young adults, and affects extremities in 36% of cases and central locations (commonly paravertebral regions) in the remainder. The differential diagnosis includes other small, blue, round cell tumours. A clinical case of EES involving a great toe in a young boy is reported. EES diagnosis was confirmed by features of histological analysis and immunohistochemistry, and by the presence of the t(11;22) chromosomal translocation.
骨外尤文肉瘤(EES)是一种罕见的软组织恶性肿瘤,组织学上与骨尤文肉瘤相似。它主要发生于青少年和年轻成年人,36%的病例累及四肢,其余病例累及身体中央部位(通常为椎旁区域)。鉴别诊断包括其他小的蓝色圆形细胞肿瘤。本文报告了1例累及小男孩大脚趾的EES临床病例。通过组织学分析、免疫组化特征以及t(11;22)染色体易位的存在确诊为EES。
