| 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) |
| Hurthle cell carcinoma | A neoplasm of the thyroid gland composed of polyhedral acidophilic cells, thought by some to be oncocytes; it may be benign or malignant, the behaviour of the latter depending on the general microscopic pattern, whether follicular, papillary, or undifferentiated. See: Hurthle cell adenoma. Synonym: Hurthle cell carcinoma. (05 Mar 2000) |
| signet-ring cell carcinoma | <tumour> A poorly differentiated adenocarcinoma composed of cells with a cytoplasmic droplet of mucus that compresses the nucleus to one side along the cell membrane; arises most frequently in the stomach, occasionally in the large bowel or elsewhere. (05 Mar 2000) |
| small cell carcinoma | <oncology, tumour> Common malignant neoplasm of bronchus. Cells of the tumour have endocrine like characteristics and may secrete one or more of a wide range of hormones, especially regulatory peptides like bombesin. (18 Nov 1997) |
| spindle cell 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) |
| squamous cell carcinoma | <oncology, tumour> A malignant growth originating from a squamous cell. This form of cancer can be seen on the skin, lips, inside the mouth, throat or oesophagus. (27 Sep 1997) |
| 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) |
| nevoid basal cell carcinoma syndrome | <syndrome> An inherited group of defects which involve abnormalities of the skin, eyes, nervous system, endocrine, glands and bones. The condition is characterised by an unusual facial appearance and a predisposition for skin cancer. (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) |
