Klatskin's original review of 13 cases was published in 1965. Once thought to be relatively uncommon, tumours of the bifurcation of the bile duct now appear to comprise more than one-half of all bile duct cancers. (12 Dec 1998) |
| klatskin tumour | <radiology> Tumour at junction of right and left intrahepatic bile ducts, slower growth than usual cholangiocarcinoma, late to metastasize (12 Dec 1998) |
| Koenen's tumour | Multiple smooth firm nodules formed at the nail folds, often over 10 mm in length, which appear at or after puberty in some patients with tuberous sclerosis. Synonym: Koenen's tumour. (05 Mar 2000) |
| Krukenberg's tumour | A metastatic carcinoma of the ovary, usually bilateral and secondary to a mucous carcinoma of the stomach, which contains signet-ring cells filled with mucus. (05 Mar 2000) |
| krukenberg tumour | <radiology> Ovarian metastasis of stomach carcinoma, also: colon, breast, other mucin-gland organs, 6% of malignant ovarian tumours (12 Dec 1998) |
| fibroid tumour | Old term for certain fibromas and leiomyomas. (05 Mar 2000) |
| Landschutz tumour | A transplantable, possibly isoantigenic, highly virulent neoplasm which can be grown in any strain of mice; the host is killed in a few days by what is apparently an anaplastic carcinoma. (05 Mar 2000) |

| low malignant potential tumour | A neoplasm of the ovary, usually arising in young women, composed of complex epithelial hyperplasia without stromas invasion; may recur if incompletely removed surgically, but is clinically less aggressive than carcinoma. Synonym: low malignant potential tumour. (05 Mar 2000) |
| lymphocytes, tumour-infiltrating | Lymphocytes that show specificity for autologous tumour cells. Ex vivo isolation and culturing of til with interleukin-2, followed by reinfusion into the patient, is one form of adoptive immunotherapy of cancer. (12 Dec 1998) |
| absorption cell | A small glass chamber with parallel sides, in which absorption spectra of solutions can be obtained. (05 Mar 2000) |
| acid cell | One of the cell's of the gastric glands; it lies upon the basement membrane, covered by the chief cell's, and secretes hydrochloric acid that reaches the lumen of the gland through fine intracellular and intercellular canals (canaliculi).
