Spots of various kinds on the skin of children when born which have been attrihuted to the influence of the maternal imagination on the foetus in utero. They are of various appearances, some much better supplied with blood than others. Some are merely supreficial or stain- like spots, pigmentary naevi; others are prominent, Vascular tumours and often have long irregular hairs growing form them. These have usually been called Moles, Spili, Spiloma, Epichro'ses spili, &c. The red, rosy, violet or bluish spots are called by I.G.ST. Hilaire, Taches sanguines;- those of an inter mediate hue between the normal colour and black, Taches melaniennes. See Telangiectasia. When naevi are superficial, without any disposition to enlarge or spread, need not be meddled with: but all those that partake of the character of aneurism by anastomosis had better be removed, where practicable.
