| prolactin-producing adenoma | <tumour> A pituitary adenoma composed of prolactin-producing cells; it gives rise to symptoms of nonpuerperal amenorrhoea and galactorrhoea (Forbes-Albright syndrome) in women and to impotence in men. Synonym: prolactinoma. (05 Mar 2000) |

| prostatic adenoma | <tumour> A term used for the growth in benign prostatic hyperplasia. (05 Mar 2000) |
| sebaceous adenoma | <tumour> A benign neoplasm of sebaceous tissue, with a predominance of mature secretory sebaceous cells. Compare: adenoma sebaceum. (05 Mar 2000) |
| Hurthle cell adenoma | <tumour> An uncommon type of thyroid tumour characterised by abundant eosinophilic cytoplasm containing numerous mitochondria. Often malignant with widespread metastases; rarely takes up radioiodine. See: Hurthle cell tumour. (05 Mar 2000) |

| nephrogenic adenoma | <tumour> A benign tumour of the urinary bladder mucosa, composed of glandular structures resembling renal tubules. (05 Mar 2000) |
| null-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) |
| islet cell adenoma | <tumour> A benign neoplasm of the pancreas composed of tissue similar in structure to that of the islets of Langerhans; it may contain functioning beta cells, and may cause hypoglycaemia. See: insulinoma. Synonym: nesidioblastoma. (05 Mar 2000) |
| ovarian tubular adenoma | <oncology, tumour> A type of ovarian tumour whose sells secrete a male sex hormone (testosterone) causing virilisation in women. (27 Sep 1997) |
| oxyphil adenoma | <tumour> A glandular tumour composed of large cells with cytoplasm that is granular and eosinophilic due to the presence of abundant mitochondria; occurs uncommonly in the kidney, salivary glands, and endocrine glands. Synonym: oxyphil adenoma. Origin: onco-+ G. Kytos, cell, + -oma, tumour (05 Mar 2000) |
| testicular tubular adenoma | A neoplasm of the ovary, arising from the ovarian stroma, mimicking to a greater or lesser extent derivatives of the sex cord mesenchyme of the testis, and sometimes causing defeminization and virilization. (12 Dec 1998) |
