| anaplastic carcinoma of the thyroid | <oncology, tumour> An aggressive form and rare form of thyroid cancer that is one of the most rapidly growing and invasive types of thyroid cancer. It commonly occurs in people over 60 years of age and may cause obstruction of the trachea. The cause is unknown but exposure to radiation may be a factor. Thyroid function tests are usually normal. Hoarse voice, cough and coughing up blood are common symptoms. Examination may reveal nodules in the thyroid gland. Diagnosis is made via biopsy. Treatment is surgical with or without radiation therapy. (27 Sep 1997) |
| apocrine carcinoma | <tumour> A carcinoma composed predominantly of cells with abundant eosinophilic granular cytoplasm, occurring in the breast, a carcinoma of the apocrine glands. (05 Mar 2000) |
| basaloid carcinoma | <tumour> A poorly differentiated squamous cell carcinoma of the anus that has some microscopic resemblance to basal cell carcinoma of the skin, but which frequently metastasizes. (05 Mar 2000) |
| basosquamous carcinoma | <tumour> A carcinoma of the skin which in structure and behaviour is considered transitional between basal cell and squamous cell carcinoma The term should not be used for the much more common keratotic variety of basal cell carcinoma, in which the tumour cells are of basal type but which contains small foci of abrupt keratinization. Synonym: basal squamous cell carcinoma. (05 Mar 2000) |
| breast carcinoma | <oncology> The uncontrolled growth of malignant breast tissue. Breast cancer is currently the most common cancer in women and the leading cause of cancer-related death in the 15-54 age group. Strong risk factors include a prior history for breast cancer or a positive family history for breast cancer. Early detection is possible through the use of monthly breast self-examination, annual clinical exams and mammography.

| bronchiolar carcinoma | <tumour> A carcinoma, thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli; involvement may be uniformly diffuse and massive, or nodular, or lobular; microscopically, the neoplastic cells are cuboidal or columnar and form papillary structures; mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells; metastases in regional lymph nodes, and even in more distant sites, are known to occur, but are infrequent. Synonym: alveolar cell carcinoma, bronchiolar adenocarcinoma, bronchiolo-alveolar carcinoma, bronchioloalveolar adenocarcinoma. (05 Mar 2000) |
| bronchiolo-alveolar carcinoma | <tumour> A carcinoma, thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli; involvement may be uniformly diffuse and massive, or nodular, or lobular; microscopically, the neoplastic cells are cuboidal or columnar and form papillary structures; mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells; metastases in regional lymph nodes, and even in more distant sites, are known to occur, but are infrequent. Synonym: alveolar cell carcinoma, bronchiolar adenocarcinoma, bronchiolo-alveolar carcinoma, bronchioloalveolar adenocarcinoma. (05 Mar 2000) |
| bronchogenic carcinoma | <tumour> Squamous cell or oat cell carcinoma that arises in the mucosa of the large bronchi and produces a persistent productive cough or haemoptysis; local growth causes bronchial obstruction and is observed radiologically as an enlarging lung mass; malignant tumour cells can be detected in the sputum, and they metastasize early to the thoracic lymph nodes and to the brain, adrenal glands, and other organs via the bloodstream. (05 Mar 2000) |
| carcinoma | <oncology> A malignant new growth that arises from epithelium, found in skin or, more commonly, the lining of body organs, for example: breast, prostate, lung, stomach or bowel. Carcinomas tend to infiltrate into adjacent tissue and spread (metastasize) to distant organs, for example: to bone, liver, lung or the brain. Origin: Gr. Karkinoma from karkinos = crab, cancer (16 Dec 1997) |
| carcinoma 256, walker | A transplantable carcinoma of the rat that originally appeared spontaneously in the mammary gland of a pregnant albino rat, and which now resembles a carcinoma in young transplants and a sarcoma in older transplants. (12 Dec 1998) |
| carcinoma, adenoid cystic | Carcinoma characterised by bands or cylinders of hyalinised or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumours occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves. (12 Dec 1998) |
| carcinoma, adenosquamous | A mixed adenocarcinoma and squamous cell or epidermoid carcinoma. (12 Dec 1998) |
| carcinoma, adrenal cortical | A malignant neoplasm of adrenal cortical cells demonstrating partial or complete histological and functional differentiation. They are rare, comprising between only 0.05% and 0.2% of all cancers. Women develop functional adrenal cortical carcinomas more commonly than men, but men develop nonfunctioning ones more often than women. Hypercortisolism is the most common presentation for this cancer. Virilism and cushing's syndrome may also result. (12 Dec 1998) |
| carcinoma, basosquamous | A skin carcinoma that histologically exhibits both basal and squamous elements. (12 Dec 1998) |
