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.

What is xanthoma?
Xanthoma is a connective-tissue new growth characterized by the formation of yellowish, circumscribed, irregularly-shaped, variously-sized, non-indurated, flat or raised patches or tubercles.
Name the two varieties met with.
The macular or flat (xanthoma planum) and the tubercular (xanthoma tuberculatum or tuberosum). In some instances both varieties (xanthoma multiplex) are seen in the same individual.
Describe the clinical appearances of xanthoma planum.
The macular or flat variety is usually seen about the eyelids. It consists of one, several or more small or large, smooth, opaque, sharply-defined, often slightly raised, yellowish patches, looking not unlike pieces of chamois-skin implanted in the skin.
