Benign reactive mesothelial cells to me. It is so common to see nuclear size variation in mesothelial cells (i think people are worried becaue of a few cells with larger nuclei). But compare the chromatin pattern with adjacent completely benign cells, they are the same). Binucleation and multinucleation are so common in benign/reactive meso. The vacules you see in some cells are from degeneration which is common in meso too. Actually accasionl meso cells maybe even mucin stain positive. The cluster of 3 cells also is not the sign for tumor. Tumor has true "tissue fragment". These cells are "hugging" each other, which is fine for benign meso too. I have said in another case that reactive mesothelial cells are very active cells and can have brisk mitoses.
Please fight with me. I take challenges.

这个病人最后诊断为结核性胸腹炎,抗结核后治愈出院,经随防,现正常。
以下是引用mingfuyu在2008-7-3 11:10:00的发言: 这儿结核病很少,我没亲眼见过结核性胸膜炎,据说背景有很多淋巴细胞,本例没有哈? |
结核我们医院很多,总结一下我自己所见过的,结核性胸膜炎胸水有下面几种情况:
1、大量间皮细胞增生。炎症细胞少见。
2、大量淋巴细胞,间皮细胞少见。
3、大量纤维素,可见极少量间皮细胞、组织细胞和淋巴细胞,这种情况是最多见的。
4、间皮细胞与淋巴细胞大量存在,不多见。
