Multiplicity Counter--Breast: How should the multiplicity counter be coded for a 3.8 cm infiltrating duct carcinoma with two "satellite nodules" measuring 5 mm and 7mm that are not described as either metastases or multiple foci?
Include these nodules in the multiplicity counter because they are measured and are part of the final diagnosis on the pathology report.
Reportability--Breast: Is an inflammatory myofibroblastic tumor of the breast with metastasis to the lung reportable?
Inflammatory myofibroblastic tumor of the breast with metastasis to the lung is reportable. Metastasis to the lung from the breast tumor indicates that the breast tumor is malignant. All malignant neoplasms are reportable.
Grade, Differentiation--Unknown Site: Is grade coded to 9 [Cell type not determined, not stated or not applicable] for all unknown primaries?
Most unknown primaries would be coded to grade 9 [Cell type not determined, not stated or not applicable] in the Grade, Differentiation field unless the case is coded to one of the histologies for which the grade is implied, such as undifferentiated carcinoma, NOS [802034].
Reportability--Brain and CNS: Which types of neurofibromatosis are reportable to SEER? See Discussion.
Clin exam: probable neurofibromatosis, type I. On the trunk alone are >14 cafe au lait spots all at least 10mm. Both axillary regions have freckling. No palpable fibromas, spine is straight, no organomegaly. MRI of head: no abnormality.
Neurofibromatosis type I (von Recklinghausen's disease, the Elephant Man disease) is primarily tumors of the subcutaneous tissues. By itself, NF1 is not reportable. NF2 is much more likely to develop acoustic neuromas. This syndrome is reportable only when acoustic neuroma(s) is present, because the acoustic neuroma is what is reportable. This case is not reportable because none of the symptoms affect the central nervous system.
Computed Ethnicity: Should the Name--Alias field be used when generating Computed Ethnicity?
No, "Alias" is not used and should not be used to generate Computed Ethnicity. Computed Ethnicity records the ethnicity based on last name and/or maiden name using a computer algorithm. Alias is not part of the algorithm.
Histology--Breast: Does "cancerization" mean invasive for a breast tumor described as "DCIS with lobular cancerization"?
No, cancerization is not a synonym for invasive. Cells of DCIS can extend not only along the duct but also into the terminal lobules. This extension is referred to as lobular cancerization.
First Course Treatment--Lymphoma: Should the use of proton pump inhibitors be coded as treatment for lymphoma primaries in patients with H Pylori?
No, do not code proton pump inhibitors as treatment. These are used for gastric acid suppression. Proton pump inhibitors are used to treat symptoms, not the lymphoma itself.
