Incidence rate and clinicopathological features of 62 atypical fibroxanthomas in a North‐Western Spanish population

Atypical fibroxanthoma (AFX) is a mesenchymal neoplasm of unknown incidence. It has been determined that AFX is a tumour with low aggressiveness as long as it is properly diagnosed. Our objectives were to exclude pleomorphic dermal sarcomas or other skin tumours incorrectly diagnosed as AFX in our centre after applying strict diagnostic criteria and to assess the behaviour of appropriately diagnosed AFX.
