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.
Tumor Size/Corpus uteri--Endometrium: Is clinical tumor size coded to the endometrial stripe measurement or thickening in the endometrium. 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?
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.
Primary site--Brain and CNS: How is the primary site to be coded if a clinician used an MRI to diagnose a left cerebellar venous angioma? See Discussion.
Grade--Head & Neck: How should grade be coded for a tonsillar primary (or other solid tumor) with resection pathology final diagnosis of poorly differentiated SCC with histologic grade: G2-3 of 3. See discussion.
Residence at dx: After living elsewhere (Florida) and traveling around the country in an RV with his spouse, is a patient a resident of this area for either primary if he was diagnosed with his first primary less than a month after arriving in the area and a second primary more than a year after parking his RV here?
