  • Usually interdigital nerves.

Etiology:

  • Indirect nerve trauma.

Clinical:[2]

  • Foot pain.

LESION, THIRD WEB SPACE OF RIGHT FOOT ("MORTON'S NEUROMA"), EXCISION:
- CONSISTENT WITH MORTON'S NEUROMA.

Micro

The sections show soft tissue with larger nerves with extensive fibrosis around and within the nerve. There is no significant nuclear atypia. Mitotic activity is not readily apparent.
