这些上皮样细胞组成的巢状结构代表性索间质分化,可以表达CK、inhibin 和calretinin,但EMA和Desmin一般不表达。至于是否诊断所谓类似卵巢性索间质肿瘤的子宫肿瘤(uterian tumors resembling ovarian sex-cord tumors,UTROST)要看这些结构的多少,所给图片中图9可见大量梭形细胞成分,可能是子宫内膜间质肉瘤成分。因此如果这些上皮样结构较少,可以诊断子宫内膜间质肉瘤伴性索样分化,如果大部分都是这种结构,可以诊断UTROST。建议做相关免疫组化包括CD10进一步明确。请看文献中的相关描述: Uterine tumors resembling ovarian sex-cord tumors (UTROSCTs) were first described in 1976 (1). In that article, Clement and Scully described two histopathologic types of these unusual tumors: group 1, in which sex cord-like differentiation is a minor component of an endometrial stromal neoplasm; and group 2, in which the sex cord-like component constitutes most of the tumor. Subsequently, it has been suggested that group-1 neoplasms be classified as endometrial stromal tumors with sex cord-like differentiation, and that the designation UTROSCT be restricted to the group-2 neoplasms
