| adenoacanthoma | <tumour> A malignant neoplasm consisting chiefly of glandular epithelium (adenocarcinoma), usually well differentiated, with foci of metaplasia to squamous (or epidermoid) neoplastic cells. Synonym: adenoid squamous cell carcinoma. (05 Mar 2000) |
| adenoameloblastoma | A benign epithelial odontogenic tumour appearing radiographically as a well-circumscribed radiolucent-radiopaque lesion usually surrounding the crown of an impacted tooth in an adolescent or young adult; characterised histologically by columnar cells organised in a duct-like configuration interspersed with spindle-shaped cells and amyloid-like deposition that gradually undergoes dystrophic calcification. Synonym: adenoameloblastoma, ameloblastic adenomatoid tumour. (05 Mar 2000) |

| adenocarcinoma, bronchiolo-alveolar | 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. 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 in even more distant sites, are known to occur, but are infrequent. (12 Dec 1998) |
| adenocarcinoma, clear cell | An adenocarcinoma characterised by the presence of varying combinations of clear and hobnail-shaped tumour cells. There are three predominant patterns described as tubulocystic, solid, and papillary. These tumours, usually located in the female reproductive organs, have been seen more frequently in young women since 1970 as a result of the association with intrauterine exposure to diethylstilbestrol. (12 Dec 1998) |
| adenocarcinoma, follicular | An adenocarcinoma of the thyroid gland, in which the cells are arranged in the form of follicles. (12 Dec 1998) |
