All terms in NCIT

Label	Id	Description
Epithelial-Myoepithelial Carcinoma	NCIT_C4199	[A malignant neoplasm which occurs mostly in the major salivary glands (most frequently in the parotid gland), but also in the minor salivary glands of the oral mucosa and the tracheobronchial tree. It is characterized by the presence of ductal structures which are lined by an inner layer of cuboidal epithelial-type cells and an outer layer of myoepithelial cells with clear or eosinophilic cytoplasm.]
Salivary Gland Polymorphous Low Grade Adenocarcinoma	NCIT_C35702	[A low grade malignant epithelial neoplasm arising from the salivary gland. It usually arises from the oral cavity, with approximately 60% of the cases involving the palate. The most common presenting sign is a painless mass in the palate. It is characterized by the presence of uniform, small to medium size malignant epithelial cells and an infiltrating pattern. There is a variety of morphologic patterns which may be present within an individual tumor, including lobular, papillary, papillary-cystic, cribriform, and trabecular pattern. It usually has a favorable clinical outcome and a low metastatic potential.]
Low Grade Salivary Gland Carcinoma	NCIT_C8012	[A salivary gland carcinoma with low grade histopathologic features. It includes the salivary gland polymorphous low grade adenocarcinoma, salivary gland low grade cribriform cystadenocarcinoma, and low grade salivary gland mucoepidermoid carcinoma. It usually follows a non-aggressive clinical course.]
Salivary Gland Adenocarcinoma	NCIT_C8021	[An adenocarcinoma arising from the salivary gland. It includes the salivary gland polymorphous low grade adenocarcinoma, salivary gland oncocytic carcinoma, salivary gland mucinous adenocarcinoma, salivary gland low grade cribriform cystadenocarcinoma, salivary gland cystadenocarcinoma, salivary gland basal cell adenocarcinoma, salivary gland acinic cell carcinoma, salivary duct carcinoma, and salivary gland adenocarcinoma not otherwise specified.]
Trichomonas Infection	NCIT_C35720	[An infection that is caused by Trichomonas.]
Protozoal Infection	NCIT_C34953	[An infection that is caused by protozoans.]
Thymic Undifferentiated Carcinoma	NCIT_C35718	[A rare primary thymic carcinoma, characterized by an undifferentiated solid tumor growth, without associated sarcomatoid features.]
Thymic Carcinoma	NCIT_C7569	[A diverse group of carcinomas of the thymus gland, previously known as thymoma type C. It includes morphologic variants derived from purely epithelial cells, as well as from cells with neuroendocrine differentiation.]
Undifferentiated Carcinoma	NCIT_C3692	[A usually aggressive malignant epithelial neoplasm composed of atypical cells which do not display evidence of glandular, squamous, or transitional cell differentiation.]
Non-Neoplastic Genitourinary System Disorder	NCIT_C156664	[A non-neoplastic disorder that affects the genitourinary system.]
Idiopathic Interstitial Pneumonia	NCIT_C35714	[Non-infectious inflammation of the interstitial lung tissue. This category includes the desquamative interstitial pneumonia, usual interstitial pneumonia, lymphocytic interstitial pneumonia, acute interstitial pneumonia, and nonspecific interstitial pneumonia.]
Interstitial Pneumonia	NCIT_C27006	[Inflammation of interstitial lung tissue, usually associated with infection.]
Usual Interstitial Pneumonia	NCIT_C35715	[Interstitial pneumonia characterized by the presence of fibrosis in the interstitial lung tissue. The pathologic diagnosis is based on the identification of fibrotic lesions at different stages of development within a lung biopsy specimen. Typically there are foci of normal lung parenchyma alternating with interstitial inflammation and honeycombing. The term usual interstitial pneumonia sometimes is used interchangeably with idiopathic interstitial fibrosis. The two terms are not entirely synonymous. Usual interstitial pneumonia may be associated with other conditions such as connective tissue disorders and asbestosis. The diagnosis of idiopathic interstitial fibrosis requires the exclusion of such conditions. Patients with usual interstitial pneumonia present with progressive dyspnea, cough, and restrictive pulmonary function abnormalities. The prognosis is usually poor.]
Idiopathic Pulmonary Fibrosis	NCIT_C35716	[Chronic and progressive fibrosis of the lung parenchyma of unknown cause.]
Pulmonary Fibrosis	NCIT_C26869	[Chronic progressive interstitial lung disorder characterized by the replacement of the lung tissue by connective tissue, leading to progressive dyspnea, respiratory failure, or right heart failure. Causes include chronic inflammatory processes, exposure to environmental irritants, radiation therapy, autoimmune disorders, certain drugs, or it may be idiopathic (no identifiable cause).]
Nonspecific Interstitial Pneumonia	NCIT_C35717	[Idiopathic interstitial pneumonia characterized by chronic inflammation and fibrosis in the interstitial lung tissue. It includes cases that cannot be classified into one of the other types of idiopathic interstitial pneumonia.]
Triple A Syndrome	NCIT_C35710	[An autosomal recessive condition caused by mutation(s) in the AAAS gene encoding the protein ALADIN, and characterized by primary adrenal insufficiency, esophageal dysmotility, and absence of tear production.]
Testicular Teratoma with Somatic-Type Malignancy	NCIT_C35711	[A testicular teratoma associated with a distinct secondary component that resembles a somatic-type malignant neoplasm (e.g., carcinoma or sarcoma).]
Teratoma with Somatic-Type Malignancy	NCIT_C4289	[A teratoma which is characterized by morphologic transformation to malignancy and an aggressive clinical course. The malignant component most often is sarcomatous or carcinomatous.]
Malignant Testicular Non-Seminomatous Germ Cell Tumor	NCIT_C5027	[A classification of testicular cancers that arise in specialized sex cells called germ cells. Nonseminomas include embryonal carcinoma, teratoma, choriocarcinoma, and yolk sac tumor.]
