Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a lymph node biopsy reveals "malignant lymphoma, peripheral T-cell type, with some features of angioimmunoblastic T-cell lymphoma and follicular T-cell lymphoma," the bone marrow biopsy was negative for involvement, and the oncologist states this patient has "peripheral T-cell lymphoma"? See Discussion.
Reportability--Colon: Would a carcinoid tumor, NOS, of the appendix with perineural or angiolymphatic invasion be reportable if there is no mention of malignancy in the pathology report?
Reportability/Primary Site: What is the reportability status and primary site for a papillary carcinoma of thyroid tissue arising in an otherwise benign mature monodermal cystic teratoma (struma ovarii)? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How is primary site coded for a myeloid sarcoma (granulocytic sarcoma) arising in the chest wall in a patient that has a negative bone marrow biopsy? See Discussion.
MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned if a pathology specimen reveals an infiltrating mammary carcinoma with mixed tubular and lobular features, 2.3 cm, low grade cribriform in situ ductal carcinoma, and Paget disease of the overlying skin with ulceration? See Discussion.
Primary site/Histology--Heme & Lymphoid Neoplasms: How are these fields coded for a case with pathologic diagnosis of "anaplastic large cell lymphoma, ALK-negative" involving the brain and a clinical statement of involvement in the right inguinal lymph nodes and the right lower extremity by a cutaneous lymphoma? See Discussion.
First course treatment--Heme & Lymphoid Neoplasms: Is the use of the corticosteroid, Clobetasol, cancer-directed treatment for mycosis fungoides or is it only used to treat the side effects of that disease?
Grade: Can the nuclear grade value be coded in the grade field for any site, or is it restricted to sites where it is specifically listed as an option in the coding manual, i.e., breast, kidney, urinary sites, etc.?
Surgery of Primary Site--Brain and CNS: How should this field be coded when the procedure is stated to be a "stereotactic CORE biopsy" of a brain tumor? See Discussion.
MP/H Rules/Histology: The 2010 SEER Manual has omitted some useful information in the Histologic Type ICD-O-3 section, specifically the statement of "Do not revise or update the histology code based on subsequent recurrence(s)". Will this statement be added to the revisions of the MPH rules? See Discussion.
