TUMORE ONAIRE EDO GAIZTOA

New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.
MSH

An abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Neoplasms may be benign (not cancer), or malignant (cancer).
NCI

An abnormal tissue growth resulted from uncontrolled cell proliferation. Benign neoplastic cells resemble normal cells without exhibiting significant cytologic atypia, while malignant ones exhibit overt signs such as dysplastic features, atypical mitotic figures, necrosis, nuclear pleomorphism, and anaplasia. Representative examples of benign neoplasms include papillomas, cystadenomas, and lipomas; malignant neoplasms include carcinomas, sarcomas, lymphomas, and leukemias. — 2004 (NCI)

growth of the tumor after morphology of cell has changed; cells may or may not have transformed to a cancerous state.

nádory mnohočetné endokrinní

group of specific, familial syndromes characterized by simultaneous neoplastic transformation of multiple endocrine tissues, typically the parathyroid glands, pancreatic islets, and anterior pituitary.
CSP

A group of autosomal dominant diseases characterized by the combined occurrence of tumors involving two or more ENDOCRINE GLANDS that secrete PEPTIDE HORMONES or AMINES. These neoplasias are often benign but can be malignant. They are classified by the endocrine glands involved and the degree of aggressiveness. The two major forms are MEN1 and MEN2 with gene mutations on CHROMOSOME 11 and CHROMOSOME 10, respectively.
MSH

An inherited condition that may result in the development of cancers of the endocrine system. There are several types of multiple endocrine neoplasia syndrome, and patients with each type may develop different types of cancer. The altered genes that cause each type can be detected with a blood test.
NCI

An autosomal dominant inherited neoplastic syndrome characterized by the development of various endocrine neoplasms and abnormalities in various anatomic sites. There are three types recognized: type 1 (MEN 1), caused by inactivation of the tumor suppressor gene MEN-1, type 2A (MEN 2A), caused by mutation of the RET gene, and type 2B (MEN 2B) also caused by mutation of the RET gene. Patients with MEN 1 may develop hyperparathyroidism and parathyroid gland adenomas, pituitary gland adenomas, pancreatic islet cell neoplasms, and carcinoid tumors. Patients with MEN 2A develop medullary thyroid carcinomas, and may also develop pheochromocytomas and parathyroid gland hyperplasia. Patients with MEN 2B develop medullary thyroid carcinomas and numerous neural defects including neuromas.

nádorové syndromy dědičné

The condition of a pattern of malignancies within a family, but not every individual`s necessarily having the same neoplasm. Characteristically the tumor tends to occur at an earlier than average age, individuals may have more than one primary tumor, the tumors may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance.

nefelometrie a turbidimetrie

Chemical analysis based on the phenomenon whereby light, passing through a medium with dispersed particles of a different refractive index from that of the medium, is attenuated in intensity by scattering. In turbidimetry, the intensity of light transmitted through the medium, the unscattered light, is measured. In nephelometry, the intensity of the scattered light is measured, usually, but not necessarily, at right angles to the incident light beam.

nefrektomie

Excision of a kidney. (Dorland, 28th ed)
MSH

surgical removal of a kidney.
CSP

Surgery to remove a kidney or part of a kidney. In a partial nephrectomy, part of one kidney or a tumor is removed, but not an entire kidney. In a simple nephrectomy, one kidney is removed. In a radical nephrectomy, an entire kidney, nearby adrenal gland and lymph nodes, and other surrounding tissue are removed. In a bilateral nephrectomy, both kidneys are removed.
NCI

A surgical procedure to completely or partially remove a kidney. With a complete nephrectomy, the attached adrenal gland, perinephric fat, and regional lymph nodes are often removed as well. With a partial nephrectomy, the removed tissue contains the tumor and a rim of normal renal parenchyma only.
