Schenck reports instances of menstruation from the nipple; and Richter, de Fontechia, Laurentius, Marcellus Donatus, Amatus Lusitanus, and Bierling are some of the older writers who have observed this anomaly.

Pare says the wife of Pierre de Feure, an iron merchant, living at Chasteaudun, menstruated such quantities from the breasts each month that several serviettes were necessary to receive the discharge.

Cazenave details the history of a case in which the mammary menstruation was associated with a similar exudation from the face, and Wolff saw an example associated with hemorrhage from the fauces.

In the Lancet (1840-1841) is an instance of monthly discharge from beneath the left mamma.

Finley also writes of an example of mammary hemorrhage simulating menstruation.
