| Walker carcinoma | <tumour> A transplantable carcinosarcoma 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. Synonym: Walker carcinoma. (05 Mar 2000) |
|---|---|
| colloid carcinoma | <tumour> A variety of adenocarcinoma in which the neoplastic cells secrete conspicuous quantities of mucin, and, as a result, the neoplasms are likely to be glistening, sticky, and gelatinoid in consistency. Synonym: colloid cancer, colloid carcinoma. (05 Mar 2000) |
| colon carcinoma | <radiology> Risk factors: colonic adenoma, 93% of colorectal CA arises from adenomatous polyps, 5% of adenomas 5mm in size develop into carcinoma, family history and polyposis syndromes, chronic ulcerative colitis, prominent lymphoid follicular pattern, history of endometrial and breast carcinoma, metastasis: liver (25%); retroperitoneal/mesenteric nodes (15%); hydronephrosis (13%); adrenal (10%); ovary; psoas muscle; ascites, risk of: 1% for synchronous colon carcinoma, 3% for metachronous colon CA, 3.8% for extracolonic malignancy, Dukes A: bowel wall; B: serosa/mesentery; C: lymph nodes; D: metastasis (12 Dec 1998) |
| mucinous carcinoma | <tumour> A variety of adenocarcinoma in which the neoplastic cells secrete conspicuous quantities of mucin, and, as a result, the neoplasms are likely to be glistening, sticky, and gelatinoid in consistency. Synonym: colloid cancer, colloid carcinoma. (05 Mar 2000) |
| mucoepidermoid carcinoma | <tumour> Most commonly a salivary gland carcinoma of low grade malignancy in children, but with variable malignancy in adults; composed of mucous, epidermoid, and intermediate cells, with mucous cells abundant only in low grade carcinoma's; recurrence is frequent, and high grade carcinoma's metastasize to cervical nodes. Synonym: mucoepidermoid tumour. (05 Mar 2000) |
| cylindromatous carcinoma | <tumour> A histologic type of carcinoma characterised by large epithelial masses containing round, glandlike spaces or cysts which frequently contain mucus or collagen and are bordered by a few or many layers of epithelial cells without intervening stroma, forming a cribriform pattern like a slice of Swiss cheese; perineural invasion and haematogenous metastasis are common; occurs most commonly in salivary glands. Synonym: cylindromatous carcinoma. (05 Mar 2000) |
| cystic carcinoma | <tumour> A carcinoma in which true epithelium-lined cysts are formed, or degenerative changes may result in cystlike spaces. (05 Mar 2000) |
| primary carcinoma | <tumour> Carcinoma at the site of origin, with local invasion in that organ. (05 Mar 2000) |
| primary neuroendocrine carcinoma of the skin | A rare malignant cutaneous tumour seen in sun-exposed skin of elderly patients composed of dermal nodules of small round cells with scanty cytoplasm in a trabecular pattern; the tumour cells contain cytoplasmic dense core granules resembling neurosecretory granules seen in Merkel cells. Synonym: primary neuroendocrine carcinoma of the skin, trabecular carcinoma. (05 Mar 2000) |
| sarcomatoid carcinoma | <tumour> A carcinoma composed of elongated cells, frequently a poorly differentiated squamous cell carcinoma which may be difficult to distinguish from a sarcoma. Synonym: sarcomatoid carcinoma. (05 Mar 2000) |
| hepatocellular carcinoma | <oncology, tumour> A tumour of the liver. The most common primary malignant liver tumour is hepatocellular carcinoma. Risk factors include chronic active hepatitis B and cirrhosis of the liver (for example alcohol aetiology). (27 Sep 1997) |
| prostate carcinoma | <radiology> Treatment: stages A and B: radical prostatectomy (prostate, seminal vesicles, part of bladder); some do simple prostatectomy for stage A, stage C: radiation therapy, stage D: orchiectomy and/or oestrogens stage A Tumour discovered incidentally in tissue removed for BPH, A1 Small focal involvement of one lobe, A2 Multifocal or diffuse carcinoma, Stage B Palpable carcinoma confined to prostate on digital exam, B1 Solitary nodule less than 1.5 cm, B2 Diffuse involvement of both lobes, Stage C Tumour extending through the prostate capsule; no metastasis, Stage D Metastases, usually to bone and/or pelvic lymph nodes (12 Dec 1998) |
| scar carcinoma | <tumour> Carcinoma of the lung, usually adenocarcinoma, arising from a peripheral lung scar or associated with interstitial fibrosis in a honeycomb lung. Synonym: scar cancer. (05 Mar 2000) |
| scirrhous carcinoma | <tumour> A hard carcinoma, fibrous in nature, resulting from a desmoplastic reaction by the stromal tissue to the presence of the neoplastic epithelium. Synonym: fibrocarcinoma. (05 Mar 2000) |
| secondary carcinoma | <tumour> A carcinoma that has appeared in a region remote from its site of origin, as in metastasis. Synonym: secondary carcinoma. (05 Mar 2000) |
