|---|---|
| tertiary oesophageal contractions | <radiology> Disordered up-and-down movement of bolus, 5-10% of normal adults in 4-6th decade, location: distal 2/3 of oesophagus aetiology: presbyesophagus, diffuse oesophageal spasm, hyperactive achalasia, neuromuscular disease: diabetes, Parkinsonism, ALS, MS, thyrotoxic myopathy, myotonic dystrophy, obstruction of cardia: neoplasm, distal oesophageal stricture, benign lesion, surgery (repair of HH) findings: spontaneous repetitive nonpropulsive contraction (yo-yo motion), corkscrew appearance, compartmentalization of barium (rosary bead, shish kebab) (12 Dec 1998) |
| tracheo-oesophageal fistula | <radiology> Type: Frequency, Description A: 10%, oesoph atresia without fistula B: 1%, oesoph atresia with upper fistula C: 80%, oesoph atresia with LOWER fistula D: 2%, K type: atresia with upper and lower fistulae E: 7%, H type See also: VATER syndrome (12 Dec 1998) |
| juxta-oesophageal pulmonary lymph nodes | Several nodes of the posterior mediastinal group located along either side of the oesophagus; they receive lymph from both the oesophagus and the lungs. Synonym: nodi lymphatici juxta-oesophageales pulmonales. (05 Mar 2000) |
| ulcer, oesophageal | A hole in the lining of the oesophagus (tube-like organ leading from the throat to the stomach) corroded by the acidic digestive juices secreted by the stomach cells. Ulcer formation is related to h. Pyloridus bacteria in the stomach, anti-inflammatory medications, and smoking cigarettes. Ulcer pain may not correlate with the presence or severity of ulceration. Diagnosis is made with barium X-ray or endoscopy. Complications of ulcers include bleeding and perforation. Treatment involves antibiotics to eradicate h. Pyloridus, eliminating risk factors, and preventing complications. (12 Dec 1998) |
| lower oesophageal sphincter | <anatomy> A muscular sphincter located at the junction of the oesophagus and the stomach. On closure the lower oesophageal sphincter prevents the back wash (reflux) of stomach acid into the oesophagus where it may damage the mucosa. See: gastrooesophageal reflux disease. (16 Mar 1998) |
| acinar carcinoma | <tumour> An adenocarcinoma arising from secreting cells of a racemose gland, particularly the salivary glands. Synonym: acinar carcinoma, acinic cell carcinoma, acinose carcinoma, acinous carcinoma. (05 Mar 2000) |
| acinic cell carcinoma | <tumour> An adenocarcinoma arising from secreting cells of a racemose gland, particularly the salivary glands. Synonym: acinar carcinoma, acinic cell carcinoma, acinose carcinoma, acinous carcinoma. (05 Mar 2000) |
| acinous carcinoma | <tumour> An adenocarcinoma arising from secreting cells of a racemose gland, particularly the salivary glands. Synonym: acinar carcinoma, acinic cell carcinoma, acinose carcinoma, acinous carcinoma. (05 Mar 2000) |
| adenoid cystic carcinoma | <tumour> A histologic type of carcinoma characterised by large epithelial masses containing round, glandlike spaces or cysts which frequently contain mucus or collagen and are bordered by a few or many layers of epithelial cells without intervening stroma, forming a cribriform pattern like a slice of Swiss cheese; perineural invasion and haematogenous metastasis are common; occurs most commonly in salivary glands. Synonym: cylindromatous carcinoma. (05 Mar 2000) |
| adenoid squamous cell carcinoma | <tumour> A malignant neoplasm consisting chiefly of glandular epithelium (adenocarcinoma), usually well differentiated, with foci of metaplasia to squamous (or epidermoid) neoplastic cells. Synonym: adenoid squamous cell carcinoma. (05 Mar 2000) |
| adenosquamous carcinoma | <tumour> A type of lung tumour exhibiting areas of clear cut glandular and squamous cell differentiation along with regions of the undifferentiated carcinoma. (05 Mar 2000) |
| adnexal carcinoma | <tumour> A carcinoma arising in, or forming structures resembling, skin appendages. (05 Mar 2000) |
| alveolar cell carcinoma | <tumour> A carcinoma, thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli; involvement may be uniformly diffuse and massive, or nodular, or lobular; microscopically, the neoplastic cells are cuboidal or columnar and form papillary structures; mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells; metastases in regional lymph nodes, and even in more distant sites, are known to occur, but are infrequent. Synonym: alveolar cell carcinoma, bronchiolar adenocarcinoma, bronchiolo-alveolar carcinoma, bronchioloalveolar adenocarcinoma. (05 Mar 2000) |
| anaplastic carcinoma | <tumour> Carcinoma with absence of epithelial structural differentiation. (05 Mar 2000) |
