Neuroma – pathology and pictures
- Benign tumor of nerve sheaths with fascicular structure.
- Tumor cells have elongated shape and indistinct borders.
- Nuclei are soft, rod, ‘cigarette-like’.
- At some places they are arranged in parallel pattern, pallisading like ‘boards of the fence’.
- There can be seen areas with fresh and old hemorrhages.
- When the tumor is rich in collagen fibres, it is designated as neurofibroma.
- Despite its biological maturity, due to its localization in posterior cranial fossa neurinoma of n. stаtoscusticus could cause death due to compression of medulla oblongata and brain edema with cerebellar herniation.
