| adenoma, chromophobe | A tumour of the anterior lobe of the pituitary gland whose cells do not stain readily with either acid or basic dyes and whose presence may be associated with hypopituitarism. Although classically these adenomas have been said to be composed of sparsely granulated or degranulated (nonfunctioning) cells, some contain functioning cells and may be associated with a hyperpituitary state, e.g., acromegaly or cushing's syndrome. (12 Dec 1998) |
|---|---|
| adenoma fibrosum | <oncology, tumour> A benign solid growth, usually found in the breast. (09 Oct 1997) |
| adenoma, islet cell | A benign tumour of the islets of langerhans that may occur anywhere throughout the pancreas. Such tumours may result in hyperinsulinism or zollinger-ellison syndrome. (12 Dec 1998) |
| adenoma, liver cell | A benign epithelial tumour of the liver. (12 Dec 1998) |
| adenoma, oxyphilic | A usually benign adenoma composed of oncocytes with granular, eosinophilic cytoplasm due to the presence of abundant mitochondria. It is often composed of huerthle cells found in the thyroid. It occurs uncommonly in the kidney, salivary glands, and endocrine glands. (12 Dec 1998) |
| 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) |
