Solid Tumor Rules (2022)/Histology--Bladder: Can the term configuration be used to code the more specific histology for bladder primaries diagnosed 2022 and later? See Discussion.
Multiple Primaries--Brain and CNS: Multiple cavernous hemangiomas diagnosed in 1995 are treated with radiation and steroids in 1996. A 1999 MRI states there is no interval change with the lesions in selected location since 1995. How many new primaries should be reported if a 2006 MRI states there are additional cavernous hemangiomas in other parts of the brain? See Discussion.
Solid Tumor Rules (2018/2021)/Multiple primaries--Ovary: How many primaries should be reported and for which primary site(s) when pathologist identifies bilateral ovarian high-grade serous carcinoma with involvement of the left fallopian tube (also showing serous tubal intraepithelial carcinoma (STIC))? See Discussion.
Reportability/Ambiguous Terminology--Prostate: Can you clarify why a prostate biopsy diagnosis of “highly suspicious for, but not diagnostic of adenocarcinoma, suggest another biopsy” is not reportable while a biopsy diagnosis of “atypical glands suspicious for adenocarcinoma with insufficient atypia to establish a definitive diagnosis of malignancy” is reportable? See discussion.
Solid Tumor Rules (2018)/Multiple primaries--Liver: When does a hepatocellular carcinoma (HCC) recurrence in the same area of the liver get accessioned as a new tumor following TACE/Y90/RFA? If there is a new HCC in the same area as previously treated but it is stated to be recurrent and/or progressive disease, is that evidence of a disease-free interval? If the tumor area is stated to be LR-TR and non-viable, but then a new HCC in that area is diagnosed, does that count as a disease-free interval? See Discussion.
Diagnostic confirmation--Heme & Lymphoid Neoplasms (Lymphoma): To code "3" in Diagnostic Confirmation, does the genetic testing need to confirm a specific histology or is it enough that is simply rules out others? See Discussion.
Reportability--Testis: Is demarcated scar tissue with atrophic seminiferous tubules and cortical bone consistent with burnt-out germ cell tumor and no evidence of germ cell neoplasia in situ (GCNIS) reportable? See Discussion.
Solid Tumor Rules/Histology--Head & Neck: What is the histology code of an external ear lesion when the dermatopathology report is the only available information (follow-up with the physician or pathologist is not possible) and the final diagnosis is malignant spindle cell neoplasm, most consistent with atypical fibroxanthoma? See Discussion.
