In 1886 Speth of Munich described a hypertrophy of the right breast which increased after every pregnancy.

At the age of twenty-six the woman had been five times pregnant in the space of a little over five years, and at this time the right breast hung down to the anterior superior spine of the ilium.

It weighed 20 pounds, and its greatest circumference was 25 inches.

There was no milk in this breast, although the left was in perfect lactation.
This case was one of pure hypertrophy and not an example of fibro-adenoma, as illustrated by Billroth.

Warren figures a case of diffused hypertrophy of the breast which was operated on by Porter.
