Please note the following are subject to change until the time of release.
Summary of changes made to immune related lymphoid proliferations:
Morphology concepts edits are found <<414629003 |Lymphoproliferative disorder (morphologic abnormality)|
Addresses content described in
Blue Book - Hematolymphoid neoplasms/B-cell lymphoid proliferations and lymphomas/Tumour-like lesions with B-cell predominance
Blue Book - Hematolymphoid neoplasms/B-cell lymphoid proliferations and lymphomas/Mature B-cell neoplasms/KSHV-HHV8-associated B-cell lymphoid proliferations and lymphomas
Blue Book - Hematolymphoid neoplasms/B-cell lymphoid proliferations and lymphomas/Mature B-cell neoplasms/Lymphoid proliferations and lymphomas associated with immune deficiency and dysregulation.
Changes to content:
New morphology concepts consistent with Blue Book updates and/or updated nomenclature.
1155771008 |Post-transplantation lymphoproliferation (morphologic abnormality)| is inactivated as outdated and replaced by414629003 |Lymphoproliferative disorder (morphologic abnormality)|
Disorder concepts reflecting post-transplantation conditions are modeled with a morphologic abnormality specific to the underlying disease and with the defining attribute-value pair of 255234002 |After (attribute)| = 77465005 |Transplantation to recipient (procedure)|.
1407216002 |Immunoglobulin G4-related disease (morphologic abnormality)| is a new morphology concept. Disorder concepts specific to immunoglobulin G4-related disease now contain this morphologic abnormality concept as a defining feature and are now sufficiently defined.
Fifteen new concepts added:
1407115009 | Follicular hyperplasia (morphologic abnormality) |
1407128002 | Hyaline-vascular unicentric Castleman disease (morphologic abnormality) |
1409237000 | Idiopathatic multicentic Castleman disease-thrombocytopenia, anasarca, fever-inflammatory symptoms, renal dysfunction-bone marrow reticulin fibrosis, organomegaly (morphologic abnormality) |
1407216002 | Immunoglobulin G4-related disease (morphologic abnormality) |
1407215003 | Idiopathic multicentric Castleman disease (morphologic abnormality) |
1407116005 | Infectious mononucleosis-like hyperplasia (morphologic abnormality) |
1407126003 | Kaposi sarcoma-associated herpesvirus-Human herpesvirus 8-positive germinotropic lymphoproliferative disorder (morphologic abnormality) |
1407114008 | Lymphoid hyperplasia arising in immune deficiency and/or dysregulation (morphologic abnormality) |
1407118006 | Kaposi sarcoma-associated herpesvirus-Human herpesvirus 8-positive multicentric Castleman disease (morphologic abnormality) |
1407125004 | Malignant extracavitary primary effusion lymphoma (morphologic abnormality) |
1409182007 | Malignant large B-cell lymphoma (morphologic abnormality) |
1409253002 | Multicentric Castleman disease (morphologic abnormality) |
1407129005 | Mixed-plasmacytic unicentric Castleman disease (morphologic abnormality) |
1407123006 | Polymorphic lymphoid proliferation arising in immune deficiency and/or dysregulation (morphologic abnormality) |
1407127007 | Unicentric Castleman disease (morphologic abnormality) |
Three concepts inactivated:
782919005 | Classical Hodgkin lymphoma type posttransplant lymphoproliferative disorder (morphologic abnormality) | OUTDATED | REPLACED BY | 762691001 |Classical Hodgkin lymphoma (morphologic abnormality)| |
397351004 | Post-transplant lymphoproliferative disorder, polymorphic (morphologic abnormality) | OUTDATED | REPLACED BY | 1407123006 |Polymorphic lymphoproliferative disorder arising in immune deficiency and/or dysregulation (morphologic abnormality)| |
1155771008 | Post-transplantation lymphoproliferation (morphologic abnormality) | OUTDATED | REPLACED BY | 414629003 |Lymphoproliferative disorder (morphologic abnormality)| |
