peripheral non-lactating breast infection
Last reviewed 07/2021
Infections affecting peripheral portions of the breast are uncommon, but when they occur they are often associated with a pre-existing condition such as diabetes, rheumatoid arthritis, steroid treatment and trauma. Infections may also occur as part of a condition known as granulomatous lobular mastitis.
Pilonidal abscesses may also affect the breasts, particularly in sheep shearers and hairdressers.
Infective organisms may be aerobic or anaerobic and include Staphylococcus aureus, Enterococci, Anaerobic streptococci and Bacteroides species.
As with other breast infections antibiotics should be prescribed, and if there are abscesses these should be recurrently aspirated or incised and drained.
