Nodular fasciitis appears as a single, rapidly growing, firm, subcutaneous nodule most commonly over the arm and forearm. It is associated in slightly more than one half of the cases with some tenderness or pain.

The growth consists of proliferation of young and active fibroblasts and small capillary blood vessels in a mucinous stroma. It is usually composed of a central solid mass with many irregular projections extending outward into the surrounding fat tissue thus resembling a highly invasive growth.

Benignity of this growth is well documented by long term follow-up of the cases.
