"Atypical fibroxanthomas are rapidly growing tumours associated with excessive sun exposure, i.e. UV exposure, and usually occur in elderly patients. There is also an association with immunosuppression, including post-transplant and AIDS. Rarely, it occurs in younger patients at other locations including the trunk and without a history of excessive sun exposure. Men are more frequently affected."
