This drug may be used in patients with severe fibrocystic breast disorder but only rarely due to virilizing SE
Danazol
condition where a female develops characteristics associated with male hormones (Androgens)
virilization
most common benign neoplasm of the breast
fibroadenoma of the breast
Patient population most commonly seen with fibroadenomas
young women withing 20 years of puberty, may be younger age in black women
Patient in mid 20s presents with round, mobile, rubbery, non-tender breast lesion measuring less than 5 cm
fibroadenoma
How can you differentiate fibroadenoma from a cyst?
US and aspiration
Treatment for fibroadenoma
none necessary → reassurance
if you have fibroadenoma larger than 3-4 cm it should be excised to rule out
Phyllodes tumor
fibroadenoma like tumor with cellular stroma that grows rapidly → can be benign or malignant
Phyllodes tumor
Treatment for malignant Phyllodes tumor
large excition with clear borders
do you need to perform lymph node resection with a a malignant phyllodes tumor
no → lesion metastasizes to the lungs and not the lymph nodes
milk retention cyst caused by an obstructed milk duct
galactocele
New mother who just stopped breast feeding presents with soft, cystic, mobile mass
galactocele
what is the best method to diagnose galactocele?
clinical history and aspiration

Staphylococcus aureus
risk factors for breast abscess/mastitis
breast conservation treatment, prior breast infection, breast surgery within 30 days, lactation, trauma (bite, piercing, tattoo), lesions (eczema, intertrigo), implants, smoking, poor hygeince, diabetes, autoimmune disorder
