NEUROMYOARTERIAL GLOMUS TUMOR IN THE EYELID

The normal glomus has been known to exist in the hands and feet. It is a peculiar anastomosis of arteries and veins, thickened by the presence of smooth muscle fibers, nerve fibers and peculiar epithelioid glomus cells.1It probably shares in the control of the circulation of the blood, particularly in the extremities, and in the regulation of the local and general temperature of the body.

I have studied sections of the skin of the eyelids, and no glomus has been revealed. If any are present, they must be exceedingly uncommon, and none has been reported. I have encountered a neuromyoarterial glomus tumor in the left lower
