I want to say someone else reached out a year or two on the same diagnosis. I'm not familiar with this myself, but I would suggest posing this question on our Facebook page, which may have a longer reach, and someone there may wish to chime in.
I found a great article written a few years ago with a similar subject that may provide some slight information for Mantel Cell, unfortunately, there are various conditions or mutations under this but this may provide some information. Please let us know if you were able to find more details, if all fails let your provider know you want to know where you can find more specific details or resources that consist of other patients with the same condition. Wishing you the very best!
