Atypical Fibroxanthoma is a malignant fibrous tissue abnormality that I occasionally encounter in both my The Woodlands dermatology and Conroe dermatology offices. Atypical Fibroxanthoma is a low grade cancer that is related to the more aggressive malignant fibrous histiocytoma, which is larger and deeper in the skin. Atypical Fibroxanthomas occur most often on sun exposed areas such as the ears, face and scalp in patients over the age of 50. Clinically, Atypical Fibroxanthomas appear as a bleeding crusted nodule that may ulcerate. Treatment typically involves surgical removal with Mohs surgery.
