What is an atypical Dermatofibroma?

What is Fibrohistiocytic tumor?
The fibrohistiocytic tumors of the skin are a heterogeneous group of dermal/subcutaneous mesenchymal neoplasms which show fibroblastic, myofibroblastic and histiocytic (macrophage-like) differentiation, often one beside the other in the same tumor.
Is atypical fibrous histiocytoma cancer?
Because atypical fibroxanthoma (AFX) is regarded as a fibrohistiocytic tumor with an intermediate potential, the proliferative activity of AFX was compared with that of benign and malignant fibrous histiocytomas.
What is plexiform Fibrohistiocytic tumor?

How is dermatofibroma treated?

What is a Dermatofibroma?

Is atypical Fibroxanthoma malignant?
Atypical fibroxanthoma (AFX) is an uncommon, pleomorphic, spindle cell cutaneous malignancy that most commonly presents as a solitary red or pink papule or nodule on the head or neck (picture 1A) [1]. Exposure to ultraviolet light most likely contributes to the development of AFX.
Should a histiocytoma be removed?
On the average, a histiocytoma undergoes regression by itself within three months. Any growth believed to be a histiocytoma that is still present after 3 months should be removed. Any histiocytoma that is eroded or seems uncomfortable should be removed rather than waiting through the regression process.
What is a plexiform neurofibroma?

What kind of tumor is atypical fibroxanthoma?

What are the three subtypes of fibrohistiocytic tumor?
Subtypes are fibrohistiocytic (histiocyte-like cells and giant cells), fibroblastic (fibroblast-like cells) and mixed

Atypical fibroxanthoma (AFX) is a tumor that occurs primarily in older individuals after the skin of the head and neck has been damaged significantly by sun exposure and/or therapeutic radiation.
