• A breast abscess is a collection of pus that develops into the breast.

BREAST ABSCESSBREAST ABSCESS
• Most common in first 6 weeks
• 5-11% of mastitis cases
• Affect future lactation in 10% of affected ♀
• No differences b/t groups by age, parity, localization of infection, cracked nipples, + milk cultures.
• Duration of symptoms: only independent variable favoring abscess development

MILK STASISMILK STASIS
– Stagnant milk increases pressure in breast leading to leakage in surrounding breast tissue
– Milk, itself, causes an inflammatory response
• +/- Infection
– Milk provides medium for bacterial growth

Puerperal mastitisPuerperal mastitis• Puerperal mastitis is the inflammation of
the breast in connection with pregnancy and breastfeeding.
• it is caused by blocked milk ducts.
![Page 14: Mastitis](https://reader033.vdocument.in/reader033/viewer/2022042819/55cf27b6bb61eb83548b45c4/html5/thumbnails/14.jpg)
Nonpuerperal mastitisNonpuerperal mastitis
• The term nonpuerperal mastitis describes inflammatory lesions of the breast occurring unrelated to pregnancy and breastfeeding.

STAGESSTAGES
Cellulitic stages
In which breast as a whole becomes red and extermely painful.
Abscess
When the abscess develops redness becomes limited to area of abscess formation.

STAGESSTAGES
• Edema ,tenderness,brawny induration are the three main features of abscess formation.

TEST AND DIAGNOSISTEST AND DIAGNOSIS
• The diagnosis of mastitis and breast abscess can usually be made based on a physical examination.
• ultrasound.
• a clear image of the breast tissue and may be helpful in distinguishing between simple mastitis and abscess
![Page 20: Mastitis](https://reader033.vdocument.in/reader033/viewer/2022042819/55cf27b6bb61eb83548b45c4/html5/thumbnails/20.jpg)
TEST AND DIAGNOSISTEST AND DIAGNOSIS
• In cases of infectious mastitis, cultures may be needed in order to determine what type of organism is causing the infection.
• Staph Aureus
Group A and B βhemolytic Strep, E Coli, H. flu
• MRSA
• Fungal infections
• TB where endemic – 1% of cases
![Page 21: Mastitis](https://reader033.vdocument.in/reader033/viewer/2022042819/55cf27b6bb61eb83548b45c4/html5/thumbnails/21.jpg)
TEST AND DIAGNOSISTEST AND DIAGNOSIS
• Mammograms or breast biopsies are normally performed on women who do not respond to treatment or on non-breastfeeding women.

Other ComplicationsOther Complications
• Distortion of breast • Chronic inflammation
![Page 27: Mastitis](https://reader033.vdocument.in/reader033/viewer/2022042819/55cf27b6bb61eb83548b45c4/html5/thumbnails/27.jpg)
TREATMENTTREATMENT
• Supportive Therapy– Rest, fluids, pain medication, anti-
inflammatory agents, • lactation mastitis• -frequent emptying of both breasts by
breastfeeding is essential. Also essential is adequate fluid supply for the mother and infant
![Page 28: Mastitis](https://reader033.vdocument.in/reader033/viewer/2022042819/55cf27b6bb61eb83548b45c4/html5/thumbnails/28.jpg)
TREATMENTTREATMENT
• For breastfeeding women with light mastitis, massage and application of heat prior to feeding can help as this may aid unblocking the ducts. However in more severe cases of mastitis heat or massage could make the symptoms worse and cold compresses are better suited to contain the inflammation
![Page 29: Mastitis](https://reader033.vdocument.in/reader033/viewer/2022042819/55cf27b6bb61eb83548b45c4/html5/thumbnails/29.jpg)
TREATMENTTREATMENT
• INFECTIOUS MASTITIS
• Dicloxacillin or cephalexin are recommended, because of the high rates of penicillin resistant staphylococci.
• Minimum treatment 10-14 days.
![Page 30: Mastitis](https://reader033.vdocument.in/reader033/viewer/2022042819/55cf27b6bb61eb83548b45c4/html5/thumbnails/30.jpg)
TREATMENTTREATMENT
• An abscess (or suspected abscess) in the breast may be treated by ultrasound-guided fine-needle aspiration (percutaneous aspiration) or by surgical incision and drainage; each of these approaches is performed under antibiotic coverage. In case of puerperal breast abscess, breastfeeding from the affected breast should be continued where possible.
