Haller, in a collection of physiologic curiosities covering a
period of a century and a half, cites 18 instances of
menstruation from the skin. Parrot has also mentioned several
cases of this nature. Chambers speaks of bloody sweat occurring
periodically in a woman of twenty-seven; the intervals, however,
were occasionally but a week or a fortnight, and the exudation
was not confined to any one locality. Van Swieten quotes the
history of a case of suppression of the menstrual function in
which there were convulsive contractions of the body, followed by
paralysis of the right arm. Later on, the patient received a blow
on the left eye causing amaurosis; swelling of this organ
followed, and one month later blood issued from it, and
subsequently blood oozed from the skin of the nose, and ran in
jets from the skin of the fingers and from the nails.

D'Andrade cites an account of a healthy Parsee lady, eighteen
years of age, who menstruated regularly from thirteen to fifteen
and a half years; the catamenia then became irregular and she
suffered occasional hemorrhages from the gums and nose, together
with attacks of hematemesis. The menstruation returned, but she
never became pregnant, and, later, blood issued from the healthy
skin of the left breast and right forearm, recurring every month
or two, and finally additional dermal hemorrhage developed on the
forehead. Microscopic examination of the exuded blood showed
usual constituents present. There are two somewhat similar cases
spoken of in French literature. The first was that of a young
lady, who, after ten years' suppression of the menstrual
discharge, exhibited the flow from a vesicular eruption on the
finger. The other case was quite peculiar, the woman being a
