Core Tip

Core Tip: Superficial CD34-positive fibroblastoma is a newly discovered mesenchymal tumor characterized by high polymorphism, low mitotic rate, and diffuse CD34-positive reactions. Microscopically, the tumors were composed of spindle-shaped to epithelioid cells with scattered bizarre and pleomorphic nuclei on a fibrous or fibromyxoid background.
