| adenoma, sweat gland | A benign neoplasm derived from epithelial cells of sweat glands. (12 Dec 1998) |
|---|---|
| adenoma, villous | An adenoma of the large intestine. It is usually a solitary, sessile, often large, tumour of colonic mucosa composed of mucinous epithelium covering delicate vascular projections. Hypersecretion and malignant changes occur frequently. (12 Dec 1998) |
| adnexal adenoma | <tumour> An adenoma arising in, or forming structures resembling, skin appendages. (05 Mar 2000) |
| adrenal adenoma | <radiology> Benign adrenal tumour, hyperfunctioning adenoma can cause, primary hyperaldosteronism, Cushing syndrome, nonfunctional adenoma seen in 2-8% of population, differentiate from metastasis, MRI: metastasis bright on T2, biopsy, follow see: adrenal mass (12 Dec 1998) |
| adrenocortical adenoma | <tumour> A benign tumour of adrenal cortical cells; small unencapuslated nodules of adrenal cortex are probably localised areas of hyperplasia rather than adenoma's; true adenoma's are rare and may be symptomless or associated with Cushing's syndrome or primary aldosteronism. (05 Mar 2000) |
| 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) |
| canalicular adenoma | <tumour> A variant of monomorphic adenoma composed of double rows of epithelial cells in long cords. (05 Mar 2000) |
| carcinoma ex pleomorphic adenoma | <tumour> Carcinoma arising in a benign mixed tumour of a salivary gland, characterised by rapid enlargement and pain. (05 Mar 2000) |
| 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. Also known as adenoma. Synonym: papillary adenoma of large intestine. (05 Mar 2000) |
