The dermatologist said that it was a cellular dermatofibroma, that it was benign, that they had to do immunohistochemistry extra staining on it as it was very "spindly". (not sure what this means) He also said it might recur but would still be clinically benign.
Can cellular dermatofibroma transform into something malignant?
It sat on my neck for two years before it was removed - could it have spread in that time but I just don't have any symptoms yet?
I have been looking on the internet and it seems that some benign-appearing cellular DF have subsequently spread, this is what really worries me.
But some of them have spread according to the internet.
Is it a sarcoma that it can transform into?
