I'm having a hard time wrapping my head around the gross morphology of sarcomas. Robbins defines sarcomas as "having little connective tissue stroma and so they are fleshy". But since sarcomas are derived from mesencymal tissues, shouldn't it be made of an abundant of connnective tissue stroma, hence making them either rubbery or firm (like a scar, especially if it's a fibrsarcoma)?

The only reason I can think sarcomas will be "soft" is if the tumor is undifferentiated.

Help!

Ive never really understood what fleshy even means. Arent lymphomas supposed to be "fleshy," too?

If that's what Robbins says, ignore it.

Sarcomas are extremely variable, and can be anything from bone/cartilage producing, to fibrous and firm, to bloody and soft, to imperceptible on a gross scale.
