| yolk sac carcinoma | Malignant germ cell tumour commonly found in the ovary. The tumour arises from primitive germ cells and develops into extra-embryonic tissue resembling the yolk sac. Synonym: yolk sac carcinoma. (05 Mar 2000) |
| latent carcinoma | <tumour> An epithelial neoplasm showing microscopic features of malignancy believed to have remained localised and asymptomatic for a long period; e.g., small carcinoma's of the prostate in old men, often found incidentally at autopsy. (05 Mar 2000) |
| lateral aberrant thyroid carcinoma | <tumour> A cervical nodule of thyroid carcinoma situated outside the thyroid gland, formerly thought to arise from ectopic thyroid tissue but now believed to be metastatic from an occult carcinoma within the gland. (05 Mar 2000) |
| leptomeningeal carcinoma | <tumour> An infiltration of carcinoma cells in the arachnoid and subarachnoid space; may be primary or secondary. Synonym: leptomeningeal carcinoma, leptomeningeal carcinomatosis, meningeal carcinomatosis. (05 Mar 2000) |
| lobular carcinoma | <tumour> A form of adenocarcinoma, especially of the breast, where lobular carcinoma is less common than ductal carcinoma and usually is composed of small cells. (05 Mar 2000) |
| lobular carcinoma in situ | <tumour> Carcinoma of the breast in which small tumour cells fill preexisting acini within lobules, without invading the surrounding stroma. Synonym: lobular carcinoma in situ, lobular neoplasia. (05 Mar 2000) |
| Lucke carcinoma | <cell biology, oncology> A renal carcinoma, caused by a herpes virus, in frogs, it aroused interest because its abnormal growth appears to be dependent on a restricted temperature range. Nuclei from these cells give rise to normal frogs if transplanted into enucleated eggs, giving support to the epigenetic theories of neoplasia. (18 Nov 1997) |
| 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) |
| acinar cell tumour | A solid and cystic tumour of the pancreas, occurring in young women; tumour cells contain zymogen granules. (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) |
