Mast cells play a key role in the inflammatory process. When activated, a mast cell can either selectively release (piecemeal degranulation) or rapidly release (anaphylactic degranulation) mediators, or compounds that induce inflammation, from storage granules into the local microenvironment.
Hallmark of the disease is the development of neurofibromas, composed of Schwann cells, fibroblasts, extracellular matrix and degranulating mast cells (Jett and Friedman, 2009). Mast cells are resident leukocytes known to play a key role in type I hypersensitivity (Walls et al., 2001). Characteristic feature is the presence of cytoplasmic metachromatic granules that occupies approximately 40% of the cell volume.
