| 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) |
| ductal carcinoma | <tumour> A carcinoma derived from epithelium of ducts, e.g., in the breast or pancreas. (05 Mar 2000) |
| ductal carcinoma in situ | <oncology, tumour> A cancer inside the ducts of breast that has not grown through the wall of the duct into the surrounding tissues. Sometimes referred to as a precancer. Good prognosis is involved with in situ cancers. (09 Oct 1997) |
| infiltrating ductal cell carcinoma | <oncology, tumour> A cancer that begins in the mammary glands and has spread to areas outside the gland. (13 Nov 1997) |
| inflammatory carcinoma | <tumour> Carcinoma of the breast presenting with oedema, hyperaemia, tenderness, and rapid enlargment of the breast; microscopically, there is extensive invasion of dermal lymphatics by the carcinoma. (05 Mar 2000) |
| intermediate carcinoma | <tumour> Obsolete term for basosquamous carcinoma (05 Mar 2000) |
