| eosinophil adenoma | <endocrinology, oncology, tumour> A benign tumour, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumours may give rise to excessive secretion of growth hormone, resulting in gigantism or acromegaly. A specific type of acidophil adenoma may give rise to nonpuerperal galactorrhoea. (25 Jun 1999) |
| tubular adenoma | <tumour> A benign neoplasm composed of epithelial tissue resembling a tubular gland. (05 Mar 2000) |
| undifferentiated cell adenoma | <tumour> An adenoma of the hypophysis composed of cells for which there is no overt evidence or hormone production, but which usually produces hypopituitarism and visual disturbances by compression of adjacent structures; approximately one third of these tumours have cells with abundant mitochondria (oncocytes) that are somewhat larger than the monocytic null cells. Synonym: undifferentiated cell adenoma. (05 Mar 2000) |
| fibroid adenoma | <oncology, tumour> A benign solid growth, usually found in the breast. (09 Oct 1997) |
| lactating adenoma | <tumour> An uncommon adenoma of the breast composed of tubuloacinar structures with pronounced secretory changes such as seen in pregnancy and lactation. (05 Mar 2000) |
| follicular adenoma | <tumour> An adenoma of the thyroid with a simple glandular pattern. (05 Mar 2000) |
| Fuchs' adenoma | <tumour> A benign epithelial tumour of the non-pigmented epithelium of the ciliary body, rarely exceeding 1 mm in diameter. (05 Mar 2000) |
| Leydig cell adenoma | <tumour> A small benign tumours of the testis that often produce testosterone, causing endocrine symptoms. Synonym: interstitial cell tumour of testis. (05 Mar 2000) |
