- may simulate carcinoma - firm, irregular, superficial mass -erythema - skin retraction and dumpling - inflammatory response: lipid-laden histiocytes, giant cells, chronic inflammatory infiltrate - resolves with fibrosis (can be confused w tumour) |
|
|
Mastitis |
- occurs during lactation (esp. primiparas) - predisposing: cutaneous fissures in nipple, breast engorgement (incomplete nursing) - Staph or Streptococci tense, hot, very painful, > acute inflammation - axilliary lymph nodes may become enlarged and tender - may progress to abscess formation that requires surgical drainage, or chronic mastitis - fibrosis |

Fibrocytic Change |
- palpable breast masses that fluctuate with the menstrual cycle and maybe associated with pain and tenderness. - However, at least 50% of women have palpably irregular breasts and, inmany women, these palpable lumps probably represent physiologic changes ratherthan a pathologic process. Thus, the term "fibrocystic change" is amore appropriate term to use. · Indeed, the vast majority of patients with fibrocystic change are not atany increased risk for developing breast cancer, although some subgroups do |
