Dilation, especially of a hollow organ.

Ectasia

 

limited dilatation of the lumen of a hollow organ or blood vessel. Ectasia may be congenital, as in the case of bronchiectasis and telangiectasia. However, the condition occurs more often as a result of stenosis, above which the lumen of a hollow organ dilates. It is treated by surgery.

Duct ectasia (peri-ductal mastitis or dilated ducts associated with inflammation) occurs in 5-9% of non-lactating women (13).
Non-infectious mastitis may result from underlying duct ectasia (periductal mastitis or plasma cell mastitis) and infrequently from foreign material (e.g., nipple piercing, breast implant, or silicone) (28, 29).
In duct ectasia, the mammary duct-associated inflammatory disease sequence involves squamous metaplasia of lactiferous ducts, causing block-age (obstructive mastopathy) with peri-ductal inflammation and possible duct rupture (16).
The differential diagnosis of granulomatous mastitis includes breast cancer, infectious process (bacterial, fungal, or parasitic abscess), autoimmune disease (Wegener's vasculitis, giant cell arteritis), duct ectasia, other rare causes linked with systemic disease (diabetes mellitus, sarcoidosis), and idiopathic granulomatous mastitis.
