促结缔组织增生性小圆细胞肿瘤(desmoplastic small round cell tumor,DSRCT)由组织起源未定的小圆形肿瘤细胞构成,伴有明显间质硬化和多种表型分化。t(11;22)(p13;q12)易位是其稳定存在的细胞遗传学特点。现报道我院1例发生于盆腔的DSRCT,通过光镜和免疫组化观察并结合相关文献,探讨其临床病理学特征,以提高对本病的认识。
Desmoplastic small round cell tumor (DSRCT) is composed of small, rounded tumor cells of undefined tissue origin with marked interstitial sclerosis and multiple phenotypic differentiation. The translocation of t (11; 22) (p13; q12) is a cytoplasmic feature of its stable existence. Now reported in our hospital 1 case occurred in the pelvic DSRCT, observed by light microscopy and immunohistochemistry and related literature, to explore its clinicopathological features in order to improve the understanding of the disease.
