| blocked tear duct | A blocked nasolacrimal duct which normally carries tears from the eyes to the nose. Commonly seen in infants, but usually resolves spontaneously by age 2-3. In adults blockage can occur from chronic sinusitis or trauma. A gentle massage of the lacrimal gland 2-3 times a day for several months may reopen the tear duct. (27 Sep 1997) |

| blunt duct adenosis | Adenosis of the breast in which the ducts are enlarged but not increased in number. (05 Mar 2000) |
| Botallo's duct | Before birth, the blood headed from the heart (via the pulmonary artery) for the lungs is shunted away from the lungs and returned to the greatest of arteries (the aorta). The shunt is through a short vessel called the ductus arteriosus. When the shunt is open, it is said to be patent (pronounced pa'tent). The patent ductus arteriosus (PDA) usually closes at or shortly after birth and blood is permtted from that moment on to course freely to the lungs. If the ductus stays open (patent), flow reverses and blood from the aorta is shunted into the pulmonary artery and recirculated through the lungs. The PDA may close later spontaneously (on its own) or need to be ligated (tied off) surgically. (12 Dec 1998) |
| bucconeural duct | The slender tubular part of the hypophysial diverticulum; the stalk of Rathke's pocket. Synonym: bucconeural duct, hypophysial duct. (05 Mar 2000) |
| carcinoma, infiltrating duct | An invasive (infiltrating) carcinoma of the breast. This carcinoma in which no special histological feature is recognised is designated nos or not otherwise specified and is by far the most common ductal tumour, accounting for almost 70% of breast cancers. It is characterised by stony hardness upon palpation. It commonly metastasizes to the axillary lymph nodes and its prognosis is the poorest of the various ductal types. (12 Dec 1998) |
| gall duct | An obsolete term for bile duct. (05 Mar 2000) |
| major sublingual duct | The duct that drains the anterior portion of the sublingual gland; it opens at the sublingual papilla. Synonym: ductus sublingualis major, Bartholin's duct. (05 Mar 2000) |
| gartner duct cyst | <radiology> Cyst in lateral wall of vagina, remnant of wolffian duct (12 Dec 1998) |
| Gartner's duct | A rudimentary vestige of the mesonephric duct in the female into which the tubules of the epoophoron open; it is located in the broad ligament of the uterus, parallel with the lateral part of the uterine tube, and in the lateral walls of the cervix and vagina. Synonym: ductus epoophori longitudinalis, ductus deferens vestigialis, Gartner's canal, Gartner's duct. (05 Mar 2000) |
| Gartner's duct cyst | <gynaecology> A closed sac on or under the vaginal mucosa that contains fluid or semi-solid material. These may occur secondary to trauma. Treatment may include surgical excision. (27 Sep 1997) |
| pancreatic duct | The excretory duct of the pancreas that extends through the gland from tail to head where it empties into the duodenum at the greater duodenal papilla. Synonym: ductus pancreaticus, Hoffmann's duct, Wirsung's canal, Wirsung's duct. (05 Mar 2000) |
| mammary duct ectasia | A noncancerous breast disease most often found in women during menopause. The ducts in or beneath the nipple become clogged with cellular and fatty debris. The duct may have gray to greenish discharge, a lump you can feel and can become inflamed, causing pain. (09 Oct 1997) |
| paramesonephric duct | Either of the two paired embryonic tubes extending along the mesonephros roughly parallel to the mesonephric duct and emptying into the cloaca; in the female, the upper parts of the ducts form the uterine tubes, while the lower fuse to form the uterus and part of the vagina; in the male, vestiges of the ducts form the vagina masculina and the appendix testis. Synonym: ductus paramesonephricus, Muller's duct, mullerian duct. (05 Mar 2000) |
| genital duct | The genital passages of the urogenital apparatus. Synonym: genital duct. (05 Mar 2000) |
