Extraskeletal Ewing's sarcoma is a rare malignant tumor of mesenchymal origin, which is histologically similar to primary osseous Ewing's sarcoma. It has been well described in deep soft tissues. However, location in cutaneous or subcutaneous tissue has rarely been reported. Being seen principally in children, it can be seen, rarely, in old men.
We present a case of subcutaneous Ewing sarcoma within the left shoulder of a 49-year-old man, without osseous involvement. Physical examination suggested a vascular tumor. Histologically, it was a small round cell tumor that marked strongly for CD99. The diagnosis of subcutaneous Ewing sarcoma was performed.
Ewing sarcoma is a rare malignant small round cell tumor of the skin and subcutaneous tissue. It should be differentiated from other cutaneous neoplasms composed of small round cells.
骨外尤文肉瘤是一种罕见的间叶源性恶性肿瘤，组织学上与原发性骨尤文肉瘤相似。它在深部软组织中已有详细描述。然而，其位于皮肤或皮下组织的情况鲜有报道。该肿瘤主要见于儿童，在老年男性中罕见。
我们报告一例49岁男性左肩皮下尤文肉瘤，无骨质受累。体格检查提示为血管性肿瘤。组织学上，它是一种小圆形细胞肿瘤，CD99染色强阳性。诊断为皮下尤文肉瘤。
尤文肉瘤是一种罕见的皮肤和皮下组织恶性小圆形细胞肿瘤。应与其他由小圆形细胞组成的皮肤肿瘤相鉴别。
