I had a look around the forum for posts that may help you but I didn't find anyone reporting having histiocytic sarcoma, I'm afraid. However I did find some information on our website about soft tissue sarcoma which might be of use, to read more please click here.
I hope this helps, but if you still have questions, please consider giving our team of cancer nurses a call to ask any questions you may have about this. Their phone number is 0808 800 4040 and are available Monday - Friday between 9 a.m -5 p.m.
