We describe a unique case of a low-grade extraskeletal osteosarcoma revealing both histologic and radiologic features reminiscent of parosteal osteosarcoma. The tumor, which had been present for 10 years, occurred in the left axilla of a 74-year-old black woman. To date, all the published cases of extraskeletal osteosarcoma have been high-grade neoplasms; to our knowledge, this is the first reported case of a low-grade extraskeletal osteosarcoma.
我们描述了一例罕见的低级别骨外骨肉瘤病例，其组织学和放射学特征均类似骨旁骨肉瘤。该肿瘤已存在10年，发生于一名74岁黑人女性的左腋窝。迄今为止，所有已发表的骨外骨肉瘤病例均为高级别肿瘤；据我们所知，这是首例报告的低级别骨外骨肉瘤病例。
