Abstract
Angioma senile was statistically observed in a total of 1802 people, of which 1552 were males and 250 females. The results obtained were as follows:
It is one of the skin changes which are due largely to age, its occurrence incidence gradually increasing as ages advance. Its occurrence is already seen rather frequently in the late teen-agers, the incidence in this group being (Occurrence incidence/Confidence limit: Upper limit-Lower limit), and it is especially noticed after 40 years of age, the incidence after 40 years being in male, and in female. The spots increase in number, after the fourth decade the majority showing two or more spots.
No difference was found in sex incidence.
It is most frequently noticed on the breast, next the back, and third the abdomen. Also, it is occasionally seen on the upper arm and the thigh. It may also appear on the neck and nape, face, head. However, it is rarely notieed on the leg and lips. In adolescence it is mostly seen on the breast and the back, and as ages advance it is likely to appear on the abdomen.
