Overview
Neuroma
Pathogenesis
- The pathogenesis of neuroma is characterized by neural degeneration with epineural and endoneural vascular hyalinization, and perineural fibrosis[1]
- Morton neuroma is characterized by being located in the 3rd web-space, between 3rd and 4th metatarsal heads,[2] or sometimes in the second or fourth interspaces
- On gross pathology, characteristic findings of neuroma, include:[3][4]
- On microscopic histopathological analysis, characteristic findings of neuroma, include:[3][4]
- Extensive fibrosis around and within the nerve
- Digital artery
- Thrombosis
- Arterial thickening
