Problem: The mass has obviously 2 components (image 5881).  
I take the cellular lesion (5887,5888,5889,5891) as reactive fibrous-inflammatory hyperplasia.  
The less cellular lesion is nodular and has more the character of a neoplastic lesion (5882, 5883,5884,5885). In addition there are 3 additional vague nodularities in the vicinity (5886).  
Thanks for your opinion.

The less cellular parts are in my view suggestive of a solitary fibrous tumor with a hemangiopericytoma-like vascularisation and a nodular growth pattern. In the other images interfering inflammatory changes are predominant.

Solitary fibrous tumours are unpredictable both in relation to their  
immunochemistry and behaviour. The majority are CD34 positive and this will  
exclude synovial sarcoma which is a differential diagnosis. The lesion will  
have to be excised(hopefully that is possible) and the patient followed up  
since micro features do not always parallel their behaviour.
