| cysteinyldopa | <chemical> 5-s-cysteinyldopa. Found in large amounts in the plasma and urine of patients with malignant melanoma. It is therefore used in the diagnosis of melanoma and for the detection of postoperative metastases. Cysteinyldopa is believed to be formed by the rapid enzymatic hydrolysis of 5-s-glutathionedopa found in melanin-producing cells. Chemical name: L-Tyrosine, 3-((2-amino-2-carboxyethyl)thio)-5-hydroxy-, (R)- (12 Dec 1998) |
| cystic | 1. Relating to the urinary bladder or gallbladder. 2. Relating to a cyst. 3. Containing cysts. Synonym: cystous. (05 Mar 2000) |
| cystic acne | <dermatology> A form of acne which results from the bacterial infection of cysts deep within the skin. Generally requires treatment with antibiotics and other agents (Isotretinoin). Without treatment cystic acne may result in scarring. (27 Sep 1997) |
| cystic adenomatoid malformation of lung | <radiology> Only true pulmonary cystic disease of newborn, three X-ray types: multicystic, walls of varying thickness, multicystic, one large dominant thin-walled cyst, solid, mediastinal shift common, cysts often contain foetal lung fluid, Treatment: surgery Cf: congenital lobar emphysema (12 Dec 1998) |
| cystic adenomatoid malformation of lung, congenital | A developmental anomaly that usually becomes apparent in the neonatal period with progressive respiratory distress. This malformation is a focal pulmonary dysplasia characterised by a multicystic mass of terminal bronchiolar structures. Ccam is classified into 3 separate types (I, II, III) depending on cyst size.
