| carcinoma, hepatocellular | Primary carcinoma of the liver cells. It ranges from a well-differentiated tumour difficult to distinguish from normal hepatocytes to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic or may form giant cells. Several classification schemes have been suggested. Hepatocellular carcinoma is very rare in the united states and western europe, but it is one of the most common cancers in eastern asia and sub-saharan africa. The cases are preponderantly male and, racially, whites have the lowest rates. (12 Dec 1998) |

| carcinoma, infiltrating duct | An invasive (infiltrating) carcinoma of the breast. This carcinoma in which no special histological feature is recognised is designated nos or not otherwise specified and is by far the most common ductal tumour, accounting for almost 70% of breast cancers. It is characterised by stony hardness upon palpation. It commonly metastasizes to the axillary lymph nodes and its prognosis is the poorest of the various ductal types. (12 Dec 1998) |
| carcinoma in situ | Cancer that involves only the cells in which it began and has not spread to other tissues. Lobular carcinoma in situ is found in the lobules of the breast. Ductal carcinoma in situ (also called intraductal carcinoma) arises in the ducts. (16 Dec 1997) |
| carcinoma, intraductal, noninfiltrating | A noninvasive (noninfiltrating) carcinoma of the breast characterised by a proliferation of malignant epithelial cells confined to the mammary ducts or lobules, without light-microscopy evidence of invasion through the basement membrane into the surrounding stroma. Its true incidence is uncertain but all noninvasive breast carcinomas comprise almost 5% of all neoplastic lesions of the female breast, with this carcinoma accounting for about 50% of these, or 2.5%-2.8% of all tumours. (12 Dec 1998) |
| carcinoma, lewis lung | A carcinoma discovered by dr. Margaret r. Lewis of the wistar institute in 1951. This tumour originated spontaneously as a carcinoma of the lung of a c57bl mouse. The tumour does not appear to be grossly haemorrhagic and the majority of the tumour tissue is a semifirm homogeneous mass. It is also called 3ll and llc and is used as a transplantable malignancy. (12 Dec 1998) |
| carcinoma, lobular | A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumours in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (12 Dec 1998) |
| carcinoma, medullary | A carcinoma composed mainly of epithelial elements with little or no stroma. Medullary carcinomas of the breast constitute 5%-7% of all mammary carcinomas; medullary carcinomas of the thyroid comprise 3%-10% of all thyroid malignancies. (12 Dec 1998) |
| carcinoma, mucoepidermoid | A tumour of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumours of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumour of the parotid. (12 Dec 1998) |
| carcinoma myxomatodes | An obsolete term for a form of colloid cancer in which there is myxomatous metaplasia of the cellular fibrous stroma. (05 Mar 2000) |
| carcinoma, neuroendocrine | A group of carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue cells", granular chromatin, and an attenuated rim of poorly demarcated cytoplasm. Neuroendocrine tumours include carcinoids, small ("oat") cell carcinomas, medullary carcinoma of the thyroid, merkel cell tumour, cutaneous neuroendocrine carcinoma, pancreatic islet cell tumours, and pheochromocytoma. Neurosecretory granules are found within the tumour cells. (12 Dec 1998) |
| carcinoma, papillary | A malignant neoplasm characterised by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. (12 Dec 1998) |
| carcinoma, papillary, follicular | A thyroid neoplasm of mixed papillary and follicular arrangement. Its biological behaviour and prognosis is the same as that of a papillary adenocarcinoma of the thyroid. (12 Dec 1998) |
| carcinoma simplex | An obsolete term for any form of carcinoma in which the relative proportions of stroma and neoplastic epithelial cells are not unusual, i.e., stromal elements are not comparatively abundant, nor are they reduced in amount or lacking; an obsolete term for a carcinoma lacking any identifiable microscopic pattern, such as glandular structure. (05 Mar 2000) |
| carcinoma, skin appendage | A malignant tumour of the skin appendages, which include the hair, nails, sebaceous glands, sweat glands, and the mammary glands. (12 Dec 1998) |
| carcinoma, verrucous | A variant of well-differentiated epidermoid carcinoma that is most common in the oral cavity, but also occurs in the larynx, nasal cavity, oesophagus, penis, anorectal region, vulva, vagina, uterine cervix, and skin, especially on the sole of the foot. Most intraoral cases occur in elderly male abusers of smokeless tobacco. The treatment is surgical resection. Radiotherapy is not indicated, as up to 30% treated with radiation become highly aggressive within six months. (12 Dec 1998) |
