| klatskin's tumour | Adenocarcinoma of the common hepatic duct bifurcation. These tumours are generally small, sharply localised, and seldom metastasizing. G. 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) |

| 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) |
| Lindau's tumour | <oncology, tumour> A haemangioma, or type of tumour composed of blood vessel or angioblast cells, which occurs in the brain. (09 Oct 1997) |
| 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). Synonym: acid cell, oxyntic cell. (05 Mar 2000) |
| acidophil cell | A cell whose cytoplasm or its granules stain with acid dyes. (05 Mar 2000) |
| acinar cell | Any secreting cell lining an acinus, especially applied to the cell's of the pancreas that furnish pancreatic juice and enzymes to distinguish them from the cell's of ducts and the islets of Langerhans. Synonym: acinous cell. (05 Mar 2000) |
| acinic cell adenocarcinoma | <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) |
