Galactocele, duct ectasia and accessory breast which accounted for 0.8% (1/120) of all BBDs were seen in 3rd, 6th and 4th decade of life respectively.

Other cases (10=1.95%) included those of duct ectasia, gynaecomastia and cases in which repeated aspirates yielded only fatty tissue and hence no opinion was possible.

In females among the 154 breast lesions, most common was fibroadenoma encountered in all age groups comprising of 67 cases(43.5%).Next commonest was benign breast disease seen in 31 cases (20.12%), followed by fibrocystic disease in 17 cases (11.03%), breast abscess in 11 cases (7.14%), mastitis in 06cases(3.89%), atypical ductal hyperplasia in 08 cases(5.19%), galactocele in 04 cases (2.59%), intraductal papilloma in 03 cases (1.94%), phylloides in 03 cases (1.94%) and single case (0.64%) of mammary duct ectasia
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.
