Abstract：
UNASSIGNED: Sclerosing stromal tumor is a benign sex cord-stromal tumor, that commonly occurs in the second and third decades of age. Intraoperative diagnosis of this entity poses a great challenge because of the rare occurrence and can mimic malignant lesions. A 15-year-old female presented with a right ovarian mass. Serum markers were within normal limits. The radiological evaluation showed a large heterogeneously enhancing solid cystic abdominopelvic mass of size 16 × 14 × 9 cm with non-visualization of both ovaries separately and a few areas of calcification with mild ascites. An open cystectomy was performed. A part of the cyst wall was sent for an intraoperative frozen section. It was reported as sclerosing stromal tumor, and the post-operative specimen also confirmed the same. Areas of calcification and ossification were also identified as additional findings. We reported this case because of the uncommon occurrence, highlighting additional histological features, and also did a literature review, especially focussing on the intra-operative diagnosis.
摘要：
■硬化性间质瘤是一种良性性索间质瘤，这通常发生在第二个和第三个十年的年龄。由于罕见发生并且可以模仿恶性病变，因此对该实体的术中诊断提出了巨大挑战。一名15岁女性出现右卵巢肿块。血清标志物在正常范围内。放射学评估显示，大小为16×14×9cm的大量非均相增强的实性囊性腹盆腔肿块，两个卵巢均未分别可见，少数钙化区域伴有轻度腹水。进行了开放性膀胱切除术。囊肿壁的一部分被送往术中冷冻切片。据报道为硬化性间质瘤，术后标本也证实了这一点。钙化和骨化区域也被确定为其他发现。我们报告了这个病例，因为不常见，突出其他组织学特征，并做了文献综述，尤其是集中于术中诊断。
