20130220 Reportability--Thyroid: Is a hyalinizing trabecular neoplasm of the thyroid reportable? Pathology comment states: Hyalinizing trabecular neoplasm is considered by some to represent a variant of papillary thyroid carcinoma because of the similar nuclear cytology, immunoprofile and RET-oncogene rearrangements. Final Dec 12 2013
20130219 Date of diagnosis/Ambiguous terminology--Breast: I have 3 scenarios for which we disagree on whether this is the date of diagnosis or not. Mammogram - nothing in body of mammogram for any suspicion or malignancy. See discussion. Final Dec 10 2013
20130215 Reportability--Heme & Lymphoid Neoplasms: Is this case reportable? See discussion. Final Dec 09 2013
20130214 Primary site--Heme & Lymphoid Neoplasms: Would PH20 apply to bilateral axillary and bilateral inguinal LN involvement as well, or do we code C778 (LN multiple regions)? The rule states: "Code the primary site to the specific lymph node region when multiple lymph node chains within the same region as defined by ICD-O-3 are involved. Note: Use this rule when there is bilateral involvement of lymph nodes." Final Dec 09 2013
20130213 Primary site--Heme & Lymphoid Neoplasms: What is the correct primary site code for the following scenario, and what rule does it fall under?

Patient is found to have marginal zone lymphoma which involves bilateral axillary LN, inguinal LN, bone marrow and bilateral orbits. The physician says the patient has bilateral orbital lymphoma, Stage IV.

None of the rules seem to apply when the lymphoma is present in an organ and in distant lymph nodes and bone marrow only. No regional nodes are involved.

Does rule PH22 infer that the organ should be coded primary site because it has been named by the physician? This case seems to fall between the cracks.

20130212 Reportability--Heme & Lymphoid Neoplasms: When there is a clinical diagnosis from a physician stating a patient has plasmacytoma, but the path report dated before this clinical diagnosis is negative for plasmacytoma, would this case still be reportable? Final Dec 09 2013
20130211 Multiple primaries--Heme & Lymphoid Neoplasms: Should this be abstracted as one or 2 primaries? See discussion. Final Dec 09 2013
20130209 Multiple primaries-Heme & Lymphoid Neoplasms: Should this case be interpreted as 9950/3 and 9861/3 which makes it two primaries?

Polycythemia vera diagnosed elsewhere in March of 2007, treated and positive for Jak 2. Now in our facility, bone marrow biopsy positive for acute myelogenous leukemia.

Final Dec 06 2013
20130208 Histology--Heme & Lymphoid Neoplasms: How is this histology coded using the rules?

Bone marrow shows slightly hypercellular marrow with acute myeloid leukemia non-M3 type. The flow cytometry is also consistent with acute myeloid leukemia, non-M3 type.

20130207 Multiple primaries--Heme & Lymphoid Neoplasms: Is the current diagnosis a new primary?

Multiple myeloma diagnosed >5 years prior to admission, underwent multimodality treatment. Currently suffered a fracture - path report described "plasmacytoma". The discharge summary states "multiple myeloma advanced with multiple lytic lesions".

Is this a single primary dating back to the original diagnosis? Or plasmacytoma by biopsy - new primary due to >21 day lapse since original diagnosis?
