Adenocarcinoma, Papillary
|
D000231 |
[An adenocarcinoma containing finger-like processes of vascular connective tissue covered by neoplastic epithelium, projecting into cysts or the cavity of glands or follicles. It occurs most frequently in the ovary and thyroid gland. (Stedman, 25th ed)

|
Adenocarcinoma, Scirrhous
|
D002293 |
[An adenocarcinoma with a hard (Greek skirrhos, hard) structure owing to the formation of dense connective tissue in the stroma. (From Dorland, 27th ed)
] |
|
Adenocarcinoma, Sebaceous
|
D018266 |
[A malignant tumor composed of cells showing differentiation toward sebaceous epithelium. The tumor is solitary, firm, somewhat raised, more or less translucent, and covered with normal or slightly verrucose epidermis. It may be yellow or orange. The face and scalp are the commonest sites. The growth can be slow or rapid but metastasis is uncommon. Surgery cures most of the cases. (From Rook et al., Textbook of Dermatology, 4th ed, pp2403-4)

Adenofibroma
|
D000232 |
[A benign neoplasm composed of glandular and fibrous tissues, with a relatively large proportion of glands. (Stedman, 25th ed)

Adenoidectomy

D000233 |
[Excision of the adenoids. (Dorland, 28th ed)

Adenoids
|
D000234 |
[A collection of lymphoid nodules on the posterior wall and roof of the NASOPHARYNX.

|
Adenolymphoma
|
D000235 |
[A benign tumor characterized histologically by tall columnar epithelium within a lymphoid tissue stroma. It is usually found in the salivary glands, especially the parotid.

|
Adenoma
|
D000236 |
[A benign epithelial tumor with a glandular organization.

|
Adenoma, Acidophil
|
D000239 |
[A benign tumor, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumors 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 galactorrhea. (Dorland, 27th ed)

|
Adenoma, Basophil
|
D000237 |
[A small tumor of the anterior lobe of the pituitary gland whose cells stain with basic dyes. It may give rise to excessive secretion of ACTH, resulting in CUSHING SYNDROME. (Dorland, 27th ed)

|
Adenoma, Bile Duct
|
D002759 |
[A benign tumor of the intrahepatic bile ducts.
] |
|
Adenoma, Chromophobe
|
D000238 |
[A benign tumor of the anterior pituitary in which the cells do not stain with acidic or basic dyes.
] |
|
Adenoma, Islet Cell
|
D007516 |
[A benign tumor of the pancreatic ISLET CELLS. Usually it involves the INSULIN-producing PANCREATIC BETA CELLS, as in INSULINOMA, resulting in HYPERINSULINISM.

|
Adenoma, Liver Cell
|
D018248 |
[A benign epithelial tumor of the LIVER.
] |
|
Adenoma, Oxyphilic
|
D018249 |
[A usually benign glandular tumor composed of oxyphil cells, large cells with small irregular nuclei and dense acidophilic granules due to the presence of abundant MITOCHONDRIA. Oxyphil cells, also known as oncocytes, are found in oncocytomas of the kidney, salivary glands, and endocrine glands. In the thyroid gland, oxyphil cells are known as Hurthle cells and Askanazy cells.
, A subtype of follicular adenoma in the THYROID GLAND. The Hurthle cell tumor is composed predominantly (at least 75%) or entirely of oxyphil cells. Hurthle cell neoplasms can be divided into benign and malignant categories. Malignant Hurthle cell carcinoma usually appear in patients over 60 years of age and are radioresistant.

Adenoma, Pleomorphic
|
D008949 |
[A benign, slow-growing tumor, 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 tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (Dorland, 27th ed)

Adenoma, Sweat Gland
|
D006607 |
[A benign neoplasm derived from epithelial cells of sweat glands. (Stedman, 25th ed)
] |
|
Adenoma, Villous
|
D018253 |
[An adenoma of the large intestine. It is usually a solitary, sessile, often large, tumor of colonic mucosa composed of mucinous epithelium covering delicate vascular projections. Hypersecretion and malignant changes occur frequently. (Stedman, 25th ed)
] |
|
Adenomatoid Tumor
|
D018254 |
[A small, circumscribed, benign tumor of the genital tract, composed of small glandlike spaces lined by flattened or cuboidal mesothelium-like cells. (From Dorland, 27th ed)
] |
|
Adenomatosis, Pulmonary
|
D018255 |
[A neoplastic disease in which the alveoli and distal bronchi are filled with mucus and mucus-secreting columnar epithelial cells. It is characterized by abundant, extremely tenacious sputum, chills, fever, cough, dyspnea, and pleuritic pain. (Stedman, 25th ed)
