Reportability--Colon: Would a carcinoid tumor, NOS, of the appendix with perineural or angiolymphatic invasion be reportable if there is no mention of malignancy in the pathology report?
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a lymph node biopsy reveals "malignant lymphoma, peripheral T-cell type, with some features of angioimmunoblastic T-cell lymphoma and follicular T-cell lymphoma," the bone marrow biopsy was negative for involvement, and the oncologist states this patient has "peripheral T-cell lymphoma"? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a patient diagnosed with Langerhans cell histocytosis/eosinophilic granuloma involving both the seventh rib and the right temporal bone? See Discussion.
Heme & Lymphoid Neoplasms: Is a clinical remission sufficient to change the tumor status to "disease free" for a patient on long-term chemotherapy for a diagnosis of either a chronic hematologic disease, such as CML, or a myeloproliferative disorder, such as essential thrombocythemia? See Discussion.
Histology--Heme & Lymphoid Neoplasms: How is histology coded for a pathologic diagnosis of "B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma" that was clinically referred to as a "double hit lymphoma"?
Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C499 [Blood vessels, NOS] for a case of intravascular large B cell lymphoma, Asian variant [9712/3] found in the bone marrow and liver? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: When only pathology reports are available, how should the primary site be coded when a both a bone marrow biopsy and colon biopsy demonstrate "mantle cell lymphoma"?
Reportability--Heme & Lymphoid Neoplasms: Given that there appears to be many differences in the reportability of these case types pre- and post-2010 (e.g., [refractory] thrombocytopenia), is there a list available that gives the reportability dates for these diseases? See Discussion.
Reportability--Heme & Lymphoid Neoplasms: Are "anemia of chronic disorders" or "hemolytic anemia" reportable given that a search of the Hematopoietic Database returns many different reportable conditions but no exact terminology match for either diagnosis? See Discussion.
