Diagnosis is made by immunohistochemistry. 2017-12-08 Treatment and prognosis Atypical fibroxanthomas are surgically removed and have a good prognosis. They might locally reoccur with the necessity of re-surgery.

It has invasive potential, may recur locally after excision, and very rarely metastasizes.
