The aetiology of lactational breast abscess is milk stasis due to blockage of engorged lactiferous
ducts and the following infection.
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 papilla of the nipple has a median height of 0.6 cm (0 to 1.9 cm) and approximately 23 lactiferous
sinuses traverse this area to open onto the overlying epidermis at duct orifices (Figure 1).
(185) Inability to extract milk at regular intervals is also painful: milk collects in a woman's lactiferous
ducts and this unexpressed build-up causes engorgement, blocked milk ducts, and infections.
Differential diagnosis of a BCC lesion in the NAC includes Paget's disease, eczema, adenoma of the nipple, papilloma of lactiferous
ducts, syringomatous adenoma, invasive ductal carcinoma, and melanoma.
The size of lobule and the lactiferous
duct also increased in the test animals as compared to control (Fig.
Structural lesions of papillary duct and lactiferous
sinus can be detected (Anthony et al., 2014).
Pergularia tomentosa L., commonly known as Bou Hliba in Tunisia, is a fetid smelling lactiferous
Once Heveas brasiliensis plantation has been established and it is suitable for exploitation, tapping takes place; this activity consists in make an incision in the tree's bark with a knife, letting the latex flow from the lactiferous
vessels of the tree to a gatherer cup.
With the disease of mastitis, the lactiferous
capability of mammary-gland cells is reduced along with the synthesis of fat, casein, and lactose.
Nipple adenoma is a rare and benign breast tumor of the lactiferous
ducts that develops in the superficial portion of the nipple.
Macroscopically, the lesion presents as an oval or roundish mass located within a dilated lactiferous
duct; the mass may be pedunculated or broad-based, and it generally measures a few millimeters in diameter.
