Label	Id	Description
Peripheral T-Cell Lymphoma, Not Otherwise Specified	NCIT_C4340	[A heterogenous category of nodal and extranodal mature T-cell lymphomas that do not correspond to any of the specifically defined entities of mature T-cell lymphoma in the 2017 WHO classification. Excluded from this category are tumors with a T follicular helper (TFH) cell phenotype. Variants include lymphoepithelioid lymphoma (Lennert lymphoma) and primary EBV-positive nodal T-cell or NK-cell lymphoma. The follicular variant included in the peripheral T-cell lymphomas, not otherwise specified, in the 2008 edition of the WHO classification has been moved to the category of angioimmunoblastic T-cell lymphoma and other nodal lymphomas of T follicular helper cell origin in the 2017 WHO update. The same is true for a proportion of cases previously designated as the T-zone variant, because they usually have a TFH-cell phenotype. (WHO 2017)]
Common Variant Anaplastic Large Cell Lymphoma	NCIT_C7206	[An anaplastic large cell lymphoma, characterized by CD30 positive lymphoid cells.]
Anaplastic Large Cell Lymphoma	NCIT_C3720	[A peripheral (mature) T-cell lymphoma, consisting of usually large anaplastic, CD30 positive cells. The majority of cases are positive for the anaplastic large cell lymphoma (ALK) protein. The most frequently seen genetic alteration is a t(2;5) translocation. Majority of patients present with advanced disease. The most important prognostic indicator is ALK positivity, which has been associated with a favorable prognosis. (WHO, 2001)]
Lymphohistiocytic Variant Anaplastic Large Cell Lymphoma	NCIT_C7207	[A histologic variant of anaplastic large cell lymphoma characterized by the presence of a large number of histiocytes admixed with the anaplastic lymphoma cells.]
Small Cell Variant Anaplastic Large Cell Lymphoma	NCIT_C7208	[A histologic variant of anaplastic large cell lymphoma characterized by the presence of a predominant population of small to medium size malignant cells with irregular nuclei.]
Infrequent Neoplasm	NCIT_C7201
Neoplasm by Special Category	NCIT_C7062	[A neoplasm defined by its unique characteristic as they apply to clinical presentation and course, morphologic patterns, frequency, and/or age distribution.]
Malignant Histiocytosis	NCIT_C7202	[An antiquated term referring to cases of systemic non-Hodgkin lymphomas which are composed of large, atypical neoplastic lymphoid cells and cases of hemophagocytic syndromes. In the past, cases of anaplastic large cells lymphoma were called malignant histiocytosis.]
Blastic Plasmacytoid Dendritic Cell Neoplasm	NCIT_C7203	[A clinically aggressive neoplasm derived from the precursors of plasmacytoid dendritic cells (also called professional type I interferon-producing cells or plasmacytoid monocytes), with a high frequency of cutaneous and bone marrow involvement and leukemic dissemination. (WHO 2017)]
Grade 4 Pancreatic Necrosis, CTCAE	NCIT_C146030	[Life-threatening consequences; urgent operative intervention indicated]
T-Zone Variant Peripheral T-Cell Lymphoma	NCIT_C7204	[An obsolete variant of peripheral T-cell lymphoma, not otherwise specified included in the 2008 WHO classification. These lymphomas usually have a T follicular helper (TFH) cell phenotype and have been moved to the category of angioimmunoblastic T-cell lymphoma and other nodal lymphomas of T follicular helper cell origin in the 2017 WHO update. (WHO 2017)]
Grade 4 Papilledema, CTCAE	NCIT_C146031	[Best corrected visual acuity of 20/200 or worse in the affected eye]
Papilledema, CTCAE	NCIT_C143734	[A disorder characterized by swelling around the optic disc.]
Childhood B Lymphoblastic Lymphoma	NCIT_C7209	[A B lymphoblastic lymphoma that occurs during childhood.]
Grade 4 Papulopustular Rash, CTCAE	NCIT_C146032	[Life-threatening consequences]
Grade 4 Paroxysmal Atrial Tachycardia, CTCAE	NCIT_C146033	[Life-threatening consequences; incompletely controlled medically; cardioversion indicated]
Grade 4 Pelvic Infection, CTCAE	NCIT_C146034	[Life-threatening consequences; urgent intervention indicated]
Anaplastic Large Cell Lymphoma, Lymphomatoid Papulosis-Like Histology	NCIT_C7200	[An anaplastic large cell lymphoma characterized by the presence of histopathologic features reminiscent of lymphomatoid papulosis. These features include the presence of Hodgkin-like cells in a background of acute and chronic inflammation.]
Grade 4 Penile Infection, CTCAE	NCIT_C146035	[Life-threatening consequences; urgent intervention indicated]
Grade 4 Perforation Bile Duct, CTCAE	NCIT_C146036	[Life-threatening consequences; urgent operative intervention indicated]
