A storiform, cartwheel or whorled pattern is a sign in histopathology which consists of spindle cells with elongated nuclei radiating from a center point. The name "storiform" originates from Latin storea (woven), as storiform tissue tends to resemble woven fabric on microscopy.
Skin tumors that can be classified as "storiform" are mainly:[1]
- Fibrous histiocytoma (dermatofibroma)
- Soft tissue
- Dermatofibrosarcoma protuberans
