Atypical fibroxanthoma (AFX) occurs most on sun-exposed area of the head and neck of elderly person. It has an excellent prognosis after conservative, but complete, excision. However, because of its potential, albeit small, for metastasis, it is
widely
regarded as a lowgrade sarcoma.
We present herein two cases of atypical fibroxanthoma. The case 1 was a 86-year-old female who had a small egg-sized. dome shaped nodule with erosive surface on the left cheek. The other case was a 60-year-old male who had solitary bean-sized,
noduloulcerative lesion on the vertex.
Immunohistochemical studies revealed positive reaction for vimentin and α1-antichymo trypsin. These patients have received completely total surgical excision and remained free of recurrence for a period fo about 2 years follw up.
