What causes atypical Fibroxanthoma?
What causes atypical fibroxanthoma? ยป Atypical fibroxanthoma is associated with prolonged years of sun exposure, aging, and possibly x-ray radiation exposure. Both UV radiation and x-ray radiation can cause abnormal growth of atypical spindle cells, which lead to these growths.
Is atypical Fibroxanthoma a melanoma?
A skin biopsy is the diagnostic gold standard for atypical fibroxanthoma since it is a rare condition that clinically mimics basal and squamous cell carcinomas, Merkel cell carcinomas, and amelanotic melanomas.
What is atypical fibrous histiocytoma?
Atypical fibrous histiocytoma is a distinctive variant of cutaneous fibrous histiocytoma, which is often mistaken histologically for sarcoma and which have a tendency to recur locally and a capacity to metastasize, although very rarely.
Is atypical fibroxanthoma an squamous cell carcinoma?
Atypical Fibroxanthoma/Malignant Fibrous Histiocytoma Atypical fibroxanthoma is a skin cancer often seen in sun-exposed areas. It resembles squamous cell carcinoma or basal cell carcinoma because of the presence of a pink papule or erosion. It is usually diagnosed only after biopsy.
Is Fibroxanthoma cancerous?

What is AFX in dermatology?

What is a pleomorphic dermal sarcoma?
Background: Pleomorphic dermal sarcoma (PDS) is a rare, poorly defined skin neoplasm with features similar to atypical fibroxanthoma, but with adverse histopathological characteristics indicating metastatic potential such as tumour necrosis, invasion beyond superficial subcutis or vascular and/or perineural …
