duct ectasia

An inflammatory condition of the lactiferous ducts of the breast. There may be a discharge from the nipple, inversion of the nipple, and periareolar sepsis. The ectasia may occur at any age following menarche. Even though it resembles carcinoma of the breast, it is not malignant.

Etiology

The cause is unknown, but in some cases it may be associated with hyperprolactinemia due to a pituitary tumor.

Treatment

Duct ectasia is treated with surgical drainage of the abscess and antibiotics.

In our study, 69 patients interpreted by triple assessment as benign correlated with the histopathological findings whereas of 10 malignant lumps, 10 turned out to be malignant and one cases suspicious which are later diagnosed by histopathologically duct ectasia. This gives triple assessment an overall accuracy of 98% with 100% sensitivity, 95.2% specificity in published study while in my study sensitivity and specificity were 100%.
Only one case (0.8%) of each galactocele, duct ectasia and accessory breast was noted.

Benign lesions such as intraductal papilloma and mammary duct ectasia are the reasons for pathologic nipple discharge.
Mastitis with infection may be lactational (puerperal) or non-lactational (e.g., duct ectasia).
