Rare tumor originating from myofibroblasts with histologically and immunohistologically variable composition of myofibroblasts and their precursor cells. These are dermal fibroblasts, smooth muscle cells of vessels and pericytes. Thus the tumors show overlaps of these cells with different morphology (see below myofibroma, dermal (adult).

ClassificationThis section has been translated automatically.
A distinction is made according to the age of manifestation:
- Myofibroma, dermal (adult) - see below Dermatomyofibroma
- Myofibromatosis, infantile.
