Clinic: right chest wall: Hard, fixed mass, fungating, exulcerated, 5 x 4 cm. Duration 6 years.
FNA: Low-grade sarcoma.
Received: 5 tiny fragments.
Problem: Most of the fragments: mononuclear inflammatory infiltrate (plasma cells > lymphocytes, as image 4728), but in addition there are slighlty larger cells with clear cytoplasm and distinct cell borders. The pattern of infiltration is suggestive of a sarcoma (as FNA says). What is the subtype ? Thanks !
