| adenoma, pleomorphic | A benign, slow-growing tumour, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumour presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (12 Dec 1998) |
|---|---|
| adenoma sebaceum | <radiology> Seen in tuberous sclerosis, raised, red papules on the face, mainly about the nose, misnomer: they're really perivascular fibromata (12 Dec 1998) |
| 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) |
