| 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) |
| secretory carcinoma | <tumour> Carcinoma of the breast with pale-staining cells showing prominent secretory activity, as seen in pregnancy and lactation, but found mostly in children. Synonym: juvenile carcinoma. (05 Mar 2000) |
| nasopharyngeal carcinoma | <oncology, tumour> This carcinoma, although rare in North America, is one of the commonest malignancies in men from Taiwan and southern China. Hearing loss from middle ear effusion (collection of fluid in the middle ear space), a lump in the neck and a raised lesion on the palate are among the most common findings. (27 Sep 1997) |
| noninfiltrating lobular carcinoma | <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) |
| sweat gland carcinoma | <tumour> Usually a solitary tumour, nodular and fixed to the skin and underlying structure, having slow growth for long periods followed by rapid growth and dissemination. (05 Mar 2000) |
| ductal carcinoma | <tumour> A carcinoma derived from epithelium of ducts, e.g., in the breast or pancreas. (05 Mar 2000) |
