Clínicas Quirúrgicas

Page 2: Benign breast disorders

ANATOMY

The normal breast

Page 3: Benign breast disorders

A “teardrop” shape

The asymmetry is common

Vascular supply:

medial and central portion:

perforating branches from the internal mammary artery

laterally

lateral thoracic

fascial envelope

Suspensory ligaments of Cooper

Page 4: Benign breast disorders
Page 5: Benign breast disorders

Histology Breast tissue

has two histologically distinct tissues: lobular & ductal

The lobule

-is the functional unit of the breast

Alveoli are terminal elongated tubular ducts

Around 10-100 alveoli coalesce to form larger lobular ductal units

BENIGN BREAST DISORDERS

Page 7: Benign breast disorders

Fibrocystic disease

• Refers to women with severely symptomatic breast

• S&S• Mastodynia • Breast masses • Nipple discharge

Radiographic

Clusstered micricalcifications on MMG

Treatment

Reassurance

Page 8: Benign breast disorders
Page 9: Benign breast disorders

Fibroadenoma

It is the most common breast common tumor in adolescents and young women

Patients will have multiple fibroadenomas in 10% -15% of cases

Page 10: Benign breast disorders

Characteristics

A painless, slow growing mass found on self-breast examination

Several cm.

Changes with mestrual cycle

Well circumscribed

Firm rubbery texture Diagnosis MMG popcorn calcification when degeneration Ultrasound evaluation

Page 11: Benign breast disorders
Page 12: Benign breast disorders

Treatment

Based on probability of missing a primary breast CA

-30. observation

Removal if enlarges

+30 FNA

Surgery indicated in changes

Page 13: Benign breast disorders

Giant fibroadenomas

+ 5 cm

Page 14: Benign breast disorders

Radial scar

Radial sclerosing lesions

In MMG shows a stellate, irregular spiculated mass lesion

A tissue diagnosis is required to differentiate from cancer

Page 15: Benign breast disorders
Page 16: Benign breast disorders

Fat necrosis

Inflamatory necrosis related to trauma

Macrophages laden with fat lobules. Or foreign body giant cells

Treatment

Involves reassurance without excision

Page 17: Benign breast disorders
Page 18: Benign breast disorders

Periductal mastitis Uncommon disease

dilated mammary ducts with inspissated secretions and marked periductal inflammation

S&S

include noncyclicla mastodynia; nipple retraction; thick, white creamy nipple discharge; as sterile subareolar abscesses.

History

Difficulty with breast-feeding

Treatment

Reassurance

Surgical incision and drainage

Page 19: Benign breast disorders
Page 20: Benign breast disorders

Infectious mastitis

80% are associated with breast-feeding

The most common pathogen is Staphylococcus aureus

Nonlactating women

chronic infections (actinomycosis, tb, syphilis)

autoimmune diseases (lupus erythematosus)

Most infections

begin as skin cellulitis

may be treated with antibiotics safe for feeding the infant

Page 21: Benign breast disorders
Page 22: Benign breast disorders

Galactoceles

Are breast cysts that are filled with milk

Almost exclusively seen after breast-feeding and represent silated obstructed breast ducts

Treatment

Ranges from simple aspiration to surgical incision and drainage

Page 23: Benign breast disorders
Page 24: Benign breast disorders

Mondor´s disease

Trombophlebitis of superficial veins of the breast

This affects the lower outer quadrant, presents as a pakoable, cord-like mass, burning pain

Treatment

NSAIDs

Page 25: Benign breast disorders
Page 26: Benign breast disorders

Intraductal papilloma

Most common cause of bloody nipple discharge

Lesions: small, nonpalpable, close to the nipple

Dx. Ductography

Tx. Subareolar excision

Page 27: Benign breast disorders
Page 28: Benign breast disorders

Nipple discharge

Bloody: intraductal papilloma & breast ca

Purulent: subareolar infection

Milky white: galactorrhea

Green/yellow or brown: fibrocystic disease

Page 29: Benign breast disorders

Mastodynia

2 types

Cyclie mastodynia

Continuous mastodynia

Tx

NSAIDS

Changes in life style
