younger
(turns into fat with age)
most common benign breast mass
fibroadenoma
tumor composed of fibrous tissue and glands
size/tenderness increases with estrogen
fibroadenoma
benign, usually painless lump due to injury to breast tissue
fat necrosis
(50% of patients may not report trauma)
calcified oil cyst on mammography
necrotic fat and giant cells on biopsy
fat necrosis
cystic collection of retained milk from obstructed duct
galactocele
localized inflammation of the breast associated with fever, myalgias, breast pain, and redness in breastfeeding woman
mastitis
antibiotic treatment for lactational mastitis
dicloxacillin
Bacterial infection of the breast, usually due to S. aureus
acute mastitis
Associated with breast-feeding; fissures develop in the nipple providing a route of entry for microbes
acute mastitis
Presents as an erythematous breast with purulent nipple discharge; may progress to abscess formation
acute mastitis
treatment of acute mastitis
continued breastfeeding
dicloxacillin
Necrosis of breast fat
Usually related to trauma; however, a history of trauma may not always be evident
fat necrosis
Presents as a mass on physical exam or abnormal calcification on mammography
(due to saponification)
fat necrosis
Biopsy shows necrotic fat with associated calcifications and giant cells
fat necrosis
Development of fibrosis and cysts in the breast
Presents as vague irregularity of the breast tissue (‘lumpy breast’), usually in the upper outer quadrant of postmenopausal women
fibrocystic changes
Cysts have a blue-dome appearance on gross exam
fibrocystic change
fibrocystic change is benign, but some fibrocystic-related changes are associated with an increased risk
for […]
invasive carcinoma
- Fibrosis, cysts, and apocrine metaplasia -no increased risk
- Ductal hyperplasia and sclerosing adenosis- 2x increased risk
- Atypical hyperplasia-5x increased risk
Tumor of fibrous tissue and glands
Most common benign neoplasm of the breast; usually seen in premenopausal
women
fibroadenoma
Presents as a well-circumscribed, mobile marble-like mass
Estrogen sensitive- grows during pregnancy and may be painful during the menstrual cycle
fibroadenoma
is fibroadenoma associated with an increased risk of carcinoma?
no, completely benign
there is insufficient evidence to recommend mammograms in patients over […]
