The tubercleswere both lender and painful, the pain being excruciating,paroxysmal, usually lasting in Duhrings case for an hour, andradiating. It was aggravated by temperature changes, mentalemotion, and movement. Sections of the growth in Duhrings case showed anatomicallya connective tissue stroma, interwoven with fibres for the lying parallel with one another, each fibre composed of afinely granular central substance surrounded by a sheath con-Fig. Painful neuroma of the skin ; external appearance.

There was entire absence of unstriated muscular andfibrillar connective tissue. The specimen was certainly unique,representing the true amyelinic neuromata of Virchow. InKosinskfs case, non-medullated nerve fibres and connective tissue NEUROMA 375 were also discovered. In both cases, exsection of a portion ofnerve (brachial plexus, of the one; and small sciatic, of the other)was followed by considerable diminution of the pain, and almostentire disappearance of the growths.
