Mammary fistula

A fistula on the breast or areola characterized by a tunnel that penetrates deep into the flesh and exudes pus and in some cases milk; usually attributed to an effusion of the breast, mammary welling-abscess, or mammary consumption that owing to improper treatment fails to heal.

Medicinal therapy: Treat topically with formulas such as Red Upborne Elixir (红升丹 hóng shēng dān) applied to a medicated thread that is inserted to draw out the pus. When the putridity has gone, Flesh-Engendering Powder (生肌散 shēng jī sǎn) can be used to engender flesh and close the opening. The method of threaded ligation can be used for areolar fistulas.
