Neurofibromas are composed principally of Schwann cells, fibroblasts and stromal collagen, some nerve axons, and scattered mast cells. The tumors range in size from a few millimeters to over 30 centimeters. A given patient may have a scattering of a few visible neurofibromas to hundreds of functionally and psychosocially debilitating neurofibromas.
