Morton neuroma

Morton neuroma

(mōr'tŏn),
a painful, tender focal mass lesion on one of the plantar interdigital nerves of the foot, most often that which is situated between the third and fourth metatarsal bones; attributed to either compression of the nerve between the heads of the adjacent metacarpal bones, or traction being placed on the nerve as it crosses the anterior edge of the deep transverse metatarsal ligament.

Mor·ton neu·ro·ma

(mōr'tŏn nūr-ō'mă)
Metatarsal pain caused by compression of sensory nerves by the metatarsal heads, sometimes with neuroma formation.

Morton neuroma is a focal perineural fibrosis of the plantar interdigital nerves.
We believe that the tumor described in this report and those labeled granular cell traumatic neuroma by Rosso et al are really the same lesion, with the difference that in this patient the persistent tissular injury in the vicinity of lithiasis played the role of a causal, causative, or promoting factor for the development of the tumor, in a similar way, for example, that Morton neuroma is a mechanically induced lesion that affects women who frequently wear shoes that are not designed for the physiology of the foot.
Surgical pathologists are well acquainted with the morphologic features of schwannomas, neurofibromas, traumatic or Morton neuromas, and ganglion cysts, the most common benign lesions to present as nerve masses.
