Describe neuroma.

Neuroma of the skin is an exceedingly rare disease, characterized by the formation of variously-sized, usually numerous, firm, immovable and elastic fibrous tubercles containing new nerve-elements, and accompanied by violent, paroxysmal pain. Their growth is slow and usually progressive. Later they are painful upon pressure. They are limited to one region.

The tumors are seated in the corium, extending into the deeper structure, and consist of nerve-fibres, yellow elastic tissue, blood vessels and lymphoid cells.

In the two cases reported, excision of the nerve-trunk gave, in one instance, permanent relief; in the other the effect was only temporary.
