This is difficult, but would make a guess anyway
I am impressed with some focal epithelial like nests
Would consider a few other possibilities: sarcomatoid carcinoma, epithelioid GIST, and inflammatory myofibroblastic tumor.
In addition to adequate sampling and search for relationship with any adjacent organs, IHC will be needed.

这一例很难,但愿意无论如何猜一下.给我印象的是一些灶性上皮样巢.想考虑其他几种可能:肉瘤样癌,上皮样GIST,炎性肌纤维母.另外足够的取材并寻找和任何其它脏器的关系.免疫组化是需要的.
本例我问了取材医生,应该是脾被包在肿块中.

Agree with above considerations. Would like to add metastatic tumor as possibilities such as metatstatic renal cell carcinoma or GYN tumor. As Dr. Ma's immuno panel suggests, melanoma should also be considered. Some photos have pigment, like right upper one, true pigment or ink?
