Reportability--Vulva: Is this reportable? We have begun to see the following diagnosis on biopsies of the vulva with the statement below. The diagnosis is being given as simply VULVAR INTRAEPITHELIAL NEOPLASIA, no grade is noted. See discussion.
Update to current manual/Lymphovascular invasion: Are lymphvascular invasion and lymphvascular space invasion on a pathology report the same thing or do they describe different things?
Tumor Size/Corpus uteri--Endometrium: Is clinical tumor size coded to the endometrial stripe measurement or thickening in the endometrium. See Discussion.
Multiple Primaries/Histology--Lymphoma: What is the histology code and how many primaries are there based on a gastrohepatic lymph node biopsy that shows: Nodular lymphocyte-predominant Hodgkin lymphoma with T-cell/histiocyte rich diffuse large B-cell lymphoma (DLBCL)-like transformation. If two primaries, what is the diagnosis date for each primary? See Discussion.
Histology/Heme & Lymphoid Neoplasms--Leukemia: Is this the correct histology for a case of acute myeloid leukemia (AML) with recurrent genetic abnormalities? If the only information was AML with recurrent genetic abnormalities,"what code would you use: AML, NOS (9861/3) or AML with recurrent genetic abnormalities (9896/3)? See Discussion.
Ambiguous Terminology: Should SEER's lists of ambiguous terminology be modified to reflect how pathologists and radiologists actually use these terms? See discussion.
