| microinvasive carcinoma | <tumour> A variety of carcinoma seen most frequently in the uterine cervix, in which carcinoma in situ of squamous epithelium, on the surface or replacing the lining of glands, is accompanied by small collections of abnormal epithelial cells that infiltrate a very short distance into the stroma; this may represent the earliest stage of invasion, in which the neoplastic cells are capable of intrusion but not of sustained growth in connective tissue.

| clear cell carcinoma of kidney | <radiology> Hypernephroma, renal cell carcinoma, arises from proximal collecting tubule, 10% bilateral adenocarcinoma types: papillary, alveolar, onchocytoma vascularity, 85% hypervascular (require pre-op embolization), 10% hypovascular (usually papillary type), 5% avascular associated with: tuberous sclerosis, von Hippel-Lindau syndrome see also: staging (12 Dec 1998) |
| 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) |
| wolffian duct carcinoma | A rare tumour of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognised: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumour (called also endodermal sinus tumour and yolk sac tumour), occurring chiefly in children. The latter variety may also arise in the testis. (12 Dec 1998) |
| 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) |
