| apocrine adenoma | <tumour> A solitary benign tumour occurring in women usually in the labia majora, cystic and papillary, and composed of epithelium resembling that of apocrine glands. Synonym: apocrine adenoma, hidradenoma papilliferum. (05 Mar 2000) |

| basal cell adenoma | <tumour> A benign tumour of major or minor salivary glands or other organs composed of small cells showing peripheral palisading. (05 Mar 2000) |
| basophil adenoma | <tumour> A tumour of the adenohypophysis in which the cell cytoplasm stains with basic dyes, often ACTH producing. (05 Mar 2000) |
| bronchial adenoma | <radiology> Most common benign lung tumour (but only 1/50 as common as carcinoma), malignant potential, 75% resemble carcinoid tumour or cylindroma, possibly benign form of oaT-cell tumour, haemoptysis, bronchial obstruction most likely to be air-trapping (12 Dec 1998) |

| macrofollicular adenoma | <tumour> A follicular adenoma of the thyroid, composed of large follicles containing colloid. Synonym: macrofollicular adenoma. (05 Mar 2000) |
| papillary adenoma of large intestine | <tumour> Appears as a solitary sessile, often large, tumour of colonic mucosa composed of mucinous epithelium covering delicate vascular projections; malignant change occurs frequently; hypersecretion occurs rarely. Also known as adenoma. Synonym: papillary adenoma of large intestine. (05 Mar 2000) |
| papillary cystic adenoma | <tumour> An adenoma in which the lumens of the acini are frequently distended by fluid, and the neoplastic epithelial elements tend to form irregular, fingerlike projections. (05 Mar 2000) |
| villous adenoma | <tumour> Appears as a solitary sessile, often large, tumour of colonic mucosa composed of mucinous epithelium covering delicate vascular projections; malignant change occurs frequently; hypersecretion occurs rarely.

| gonadotrophin-producing adenoma | <tumour> A rare type of pituitary adenoma that produces FSH and LH; its cells can be identified only by immunochemical techniques. (05 Mar 2000) |
| gonadotropin-producing adenoma | <tumour> A rare type of pituitary adenoma that produces FSH and LH; its cells can be identified only by immunochemical techniques. (05 Mar 2000) |
| growth hormone-producing adenoma | <tumour> An adenoma that produces the clinical picture of gigantism or acromegaly, although a third of the cells have no granules or are a mixture of acidophils and chromophobes; some tumours may secrete both growth hormone and prolactin; often an acidophil or eosinophil adenoma. (05 Mar 2000) |
