3. Benign conditions
• Breast Cysts;
• Cysts within the breast are fluid-filled,
epithelium-lined cavities that may vary in size
from microscopic to large, palpable masses
containing as much as 20 to 30 mL of fluid.
• Ocurrence1:14 women.
• Age >35, declines at menopause
• Influenced by ovarian hormone and
exogenous hormone at menopause.
5. • Fibroadenoma and Related Tumors
• These are benign solid tumours.
• Is the 2nd most common tumour after
carcinomas
• most common tumor in women younger than
30 years.
• Are well capsulated
• Well differentiated from cysts by uss
7. • Hamartoma and Adenoma
• These lesions are benign proliferations of
variable amounts of epithelium and stromal
supporting tissue.
• Mammographically and physical examination
harmatomas can not be differentiated from
fibroadenoma.
• Treatment as fibroadenoma.
8. • Breast Abscess and Infections
• Infections of the breast fall into two general
categories, lactational infections and chronic
subareolar infections associated with duct
ectasia.
9. • Lactational infections are thought to arise
from entry of bacteria through the nipple into
the duct system and are characterized by
fever, leukocytosis, erythema, and tenderness.
Infections are most often due to
Staphylococcus aureus and may be manifested
as cellulitis, termed mastitis, or as abscesses.
10. • Treated with antibiotics and emptying of the
breast.
• True abscess need I&D
11. • In non lactating women, the condition arise
from subareola duct of the breast.(AKA
periductal mastitis or duct ectasia)
• Often mixed infection
• Smoking and diabetes has an association
• Palpable mass and mammographic findings
may mimic carcinoma.
13. • Papillomas and Papillomatosis
• Solitary intraductal papillomas
• are true polyps of epithelium-lined breast
ducts
• Often less than 1 cm, but may be as long as 4-
5cm.
• Often present as bloody nipple discharge
• Treatment; excision ( circum areolar incision)
14. • Sclerosing Adenosis
• Adenosis refers to an increased number of
small terminal ductules or acini.
• May stimulate carcinoma
15. • Fat Necrosis
• Fat necrosis may follow an episode of trauma
to the breast, but frequently there is no
history of trauma. Histologically, the lesion is
composed of lipid laden macrophages, scar
tissue, and chronic inflammatory cells. This
lesion has no malignant potential.
