These tumours are usually found on the trunk and extremities and tend to be larger and slower growing.

How is atypical fibroxanthoma diagnosed?

Because atypical fibroxanthoma can look like other skin cancers, it is usually diagnosed by a pathologist after a skin biopsy or excision . The diagnosis depends on finding large, pleomorphic, fibrocytic, spindle-shaped, anaplastic tumour cells haphazardly arranged in the dermis.

What is a histologically based tumor?

Is a lesional cell atypical?

Necrosis, lymphovascular invasion and perineural invasion should not be present. Cytomorphologically, lesional cells are highly bizarre and atypical, with marked pleomorphism in size and shape, abundant eosinophilic cytoplasm, occasional multinucleation and numerous mitotic figures, including atypical forms.

Is a pleomorphic neoplasm a dermal?

Comment: Sections show a dermal, poorly differentiated pleomorphic neoplasm, characterized by large and bizarre spindled to epithelioid cells with abundant eosinophilic cytoplasm, occasional multinucleation and numerous mitotic figures. Adjacent dermis contains solar elastosis. The overlying epidermis does not have a connection to the tumor. Immunohistochemical studies show that lesional cells are positive for CD68 and negative for CAM5.2, AE1 / AE3, CD31 and S100. Overall, these features support the above interpretation.
