Reportability--Esophagus/Stomach: Are the terms "high grade dysplasia" and "severe dysplasia" synonymous with in situ for tumors in the gastrointestinal tract? See Discussion.
Reportability--Ovary: Does the ICD-O-3 term "stromal endometriosis" [8931/3] always imply a reportable malignant disease process if the pathologist also states there is "no evidence of carcinoma" in the same report? See Discussion.
MP/H Rules/Histology--Brain and CNS: How is histology coded for a left occipital parietal area tumor stated to be a "low grade neuroectodermal neoplasm most consistent with neuronal tumor but lacking classic features of ganglioma" if the pathologist states the tumor is not malignant?
MP/H Rules/Histology--Kidney, renal pelvis: How is histology coded for a tumor described as "renal cell carcinoma, clear cell with rhabdoid features"? See Discussion.
Reportability-Bladder: Is a case with a cytology diagnosis, "positive for malignancy, favor low grade papillary urothelial carcinoma" reportable if the diagnosis on a subsequent bladder biopsy showed only "urothelial neoplasm of low malignant potential"? See Discussion.
Surgery of Primary Site--Brain and CNS: Is "debulking" of a primary brain tumor coded to 21 [subtotal resection of tumor] or 30 [gross resection of tumor]?
Grade--Heme & Lymphoid Neoplasms: Is the phrase "aberrant T-cell expression" enough to code the grade field to T-cell when the final diagnosis on the pathology report is "AML with aberrant T-cell antigen expression"?
Reportability--Corpus uteri: Is gestational trophoblastic neoplasia reportable if there is no mention of metastasis but the patient has been treated with chemotherapy? See Discussion.
Behavior--Breast: How is behavior coded when a biopsy shows in situ carcinoma with a focus suspicious for invasion and a subsequent excision/resection shows only in situ carcinoma?
Multiple primaries--Heme & Lymphoid Neoplasms: Is a 10/2010 diagnosis of accelerated phase of CML following a 4/2010 diagnosis of blast phase CML a new primary? See Discussion.
