What causes a hard spot on the inner thigh with history of melanoma?
When I mentioned 6 inches below the incision, I was referring to the small incision for the groin lymph node removal of the firs two lymph nodes NOT the surgery to remove the melanoma on her foot. Please look at rest of information to tie that addendum in.
You should consult your treating doctor urgently.
I have gone through your question. I can understand your concern.
She has history of melanoma and lymphnode dissection surgery.
It can be complicationof surgery. It may be clot or may be some other complications.
So be on safe side just consult your treating doctor once. For melanoma its not urgent but it looks like some complication.
