| bronchiolar adenocarcinoma | <tumour> A carcinoma, thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli; involvement may be uniformly diffuse and massive, or nodular, or lobular; microscopically, the neoplastic cells are cuboidal or columnar and form papillary structures; mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells; metastases in regional lymph nodes, and even in more distant sites, are known to occur, but are infrequent. Synonym: alveolar cell carcinoma, bronchiolar adenocarcinoma, bronchiolo-alveolar carcinoma, bronchioloalveolar adenocarcinoma. (05 Mar 2000) |

| pancreatic adenocarcinoma | <radiology> Males (60%), blacks more than whites, risk factors: tobacco, familial pancreatitis, not EtOH!, focal mass in 95%, pancreatic head in 66%, small (low-density, hypoechoic) mass, infiltrates locally, obstructs ducts and encases vessels, metastasis to liver, local nodes See also: pancreatic neoplasms (12 Dec 1998) |
| papillary adenocarcinoma | <tumour> An adenocarcinoma containing finger-like processes of vascular connective tissue covered by neoplastic epithelium, projecting into cysts or the cavity of glands or follicles; occurs most frequently in the ovary and thyroid gland. (05 Mar 2000) |
| renal adenocarcinoma | <radiology> Hypernephroma, renal cell carcinoma, arises from proximal collecting tubule, 10% bilateral adenocarcinoma types: papillary, alveolar, onchocytoma vascularity, 85% hypervascular (require pre-op embolization), 10% hypovascular (usually papillary type), 5% avascular associated with: tuberous sclerosis, von Hippel-Lindau syndrome see also: staging (12 Dec 1998) |
| renal adenocarcinoma: staging | <radiology> Typical presentation: Haematuria . . . . . 70% Fever . . . . . . . 16% Pain . . . . . . . . 50% Polycythemia . . . . 3% Palpable mass . . . 20% Anatomic staging (TNM): T1 Small tumour, kidney not enlarged T2 Large tumour, contained within renal capsule T3 Extension into perinephric fat or renal vein T4 Invasion of adjacent organs (12 Dec 1998) |
| renal adenocarcinoma: vascularity | <radiology> 85% hypervascular (require pre-op embolization), 10% hypovascular (usually the papillary type), 5% avascular also: 10% are bilateral (12 Dec 1998) |
| mesonephric adenocarcinoma | A rare tumour of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognised: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumour (called also endodermal sinus tumour and yolk sac tumour), occurring chiefly in children. The latter variety may also arise in the testis. (12 Dec 1998) |
| clear cell adenocarcinoma | <tumour> A histologic type of renal adenocarcinoma. A histologic type of adenocarcinoma occurring chiefly in the male and female genitourinary tracts which is characterised by distinctive hobnail cell growth of neoplastic cells in sheets, papillae, and coalescing glands. (05 Mar 2000) |
| mucoid adenocarcinoma | <tumour> Sometimes applied to mucinous carcinoma, or adenocarcinoma containing mucin secreting neoplastic cells. (05 Mar 2000) |
| Lucke's adenocarcinoma | <cell biology, oncology> A renal carcinoma, caused by a herpes virus, in frogs, it aroused interest because its abnormal growth appears to be dependent on a restricted temperature range. Nuclei from these cells give rise to normal frogs if transplanted into enucleated eggs, giving support to the epigenetic theories of neoplasia. (18 Nov 1997) |
