Overview
Breast lumps may be classified according to epithelial hyperplasia into 3 subtypes: non-proliferative, proliferative disease and proliferative disease without atypia.
Breast lumps may be classified into 3 subtypes based on histological regions: lobular region, ductal region, different origins.
Classification
Classification of breast lumps based on epithelial hyperplasia[1][2]
- Approximately 65% of all benign breast disease considered as non-proliferative (NP) with relative cancer risk of 1.2, 1.4 times:
- Cyst
- The most common type in non- proliferative category[3]
- Fibrosis
- Fibroadenoma (simple)
- Columnar alteration (Simple)
- Apocrine metaplasia (simple)
- Mild ductal hyperplasia
- Cyst
- Approximately 30% of total are classified as (PD) with relative cancer risk of 1.7, 2.1 times[4]
- Usual ductal hyperplasia
- Sclerosing adenosis
- Columnar hyperplasia
- papilloma
- Radical scar
- Approximately 5% to 8% of the rest regarded to PD with atypia and relative cancer risk more than 4 times[5]
- Atypical lobar hyperplasia
- Lobular carcinoma in situ
- Atypical ductal hyperplasia
- Unclear risk
Classification of benign breast lesion regarding to histologist region:[6]
- Terminal and lobular ducts
- Acinar distention
- Intralobular connective tissue proliferation
- Sclerosing adenosis
- Fibroadenoma
- Phyllodes tumor
- Hamartoma
- Epithelial changes in terminal duct lobular units (TDLU)
- Apocrine metaplasia
- Ductal and lobular hyperplasia, usual and typical
- Papillomatosis
- Intracystic papilloma
- Ductal system
- Lesion of different origin
- Fatty tissue lesion
- Lipoma
- Liponecrosis
- Fibrous tissue lesions
- Vascular origin
- Inflammatory origin
- Mastitis/abscess
- Tuberculosis and sarcoidosis
- Foreign body granuloma and siliconoma
- Lymph node origin
- Fatty tissue lesion
