EOD-Extension--Colon: What code is used to represent this field for a mid-ascending colon primary that invades through muscularis propria and into subserosal fibroadipose tissue that also presents with a "separate serosal nodule" of carcinoma within cecum that is consistent with a tumor implant (cT3, N0, M1)?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis], because the nodule of carcinoma in the cecum is not contiguous with the mid-ascending primary colon tumor.
Reportability--Lung: Is sclerosing hemangioma of the lung with multiple regional lymph nodes metastases reportable?
No, it is not reportable. According to the WHO Classification of Lung Tumours, sclerosing hemangioma "behaves in a clinically benign fashion...Reported cases with hilar or mediastinal lymph node involvement do not have a worse prognosis."
Reportability/Histology--Skin: Is dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous overgrowth, DFSP with fibrosarcomatous component Grade 2, or DFSP with focal myxoid features (2022) reportable for 2021-2022 diagnoses?
Yes. DFSP with fibrosarcomatous overgrowth and DFSP with fibrosarcomatous component Grade 2 are synonymous with fibrosarcomatous DFSP (8832/3). Our expert pathologist also advises that DFSP with focal myxoid features is the same as DFSP, myxoid (8832/3).
MP/H Rules/Multiple primaries--Thyroid: Is medullary carcinoma of the right lobe of the thyroid, with foci of papillary microcarcinoma in both lobes, one primary with mixed histology (8347/3) or two separate primaries?
For cases diagnosed prior to 2018
Abstract two primaries, Medullary (8510/3) and papillary microcarcinoma (8260/3). Other sites rule M17 applies.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a patient is simultaneously diagnosed with multiple myeloma/plasma cell myeloma, plasmacytoma and plasma cell leukemia?
This is accessioned as one primary and the histology is coded to 9732/3 [multiple myeloma].
To arrive at this answer, it is important to first try to determine how many different unique neoplasms there are to correctly identify the number of primaries to report. Per the Heme DB, plasma cell leukemia is an obsolete term. The current term and histology code for this diagnosis is 9732/3 [plasma cell myeloma]. Plasma cell myeloma and multiple myeloma are synonyms per the Heme DB. Therefore, per Rule M2 a single primary exists when there is a single histology. That takes care of the multiple myeloma/plasma cell myeloma and plasma cell leukemia, but not the plasmacytoma.
In checking the Heme DB, the terms plasma cell myeloma and multiple myeloma are not synonyms for plasmacytoma. Therefore, we are left to determine whether the multiple myeloma/plasma cell myeloma vs the plasmacytoma represents one or two primaries.
Under the Transformation section of the Heme DB, it indicates that plasmacytoma (a chronic disease process) transforms to multiple myeloma (an acute disease process). Per Rule M9, abstract a single primary and code the acute histology when both a chronic and an acute neoplasm are diagnosed simultaneously. The histology is coded to the acute neoplasm when there is no information on the biopsy regarding which is the "later" histology. This update will be added to the Heme Manual.

Reportability/Ambiguous Terminology/Date of Diagnosis: If a "suspicious" cytology is reportable only when a later positive biopsy or a physician's clinical impression of cancer supports the cytology findings, is the Date of Diagnosis field coded to the later confirmation date rather than to the date of the suspicious cytology? Is a suspicious "biopsy" handled the same way?
Cytology reported as "suspicious" is not reportable. If the physician confirms the suspicious cytology by making a clinical diagnosis of malignancy, the Date of Diagnosis field is coded to the date of the clinical diagnosis, which may or may not be same date the cytology was performed.
Without supporting clinical documentation, the case will remain non-reportable and will not be submitted to SEER. The supporting documentation can be a physician's statement that the patient has cancer, a scan or procedure that identifies cancer, or a positive biopsy.
Suspicious "biopsies" are reportable according to SEER's list of ambiguous terms. Suspicious "cytologies" without supporting clinical statements are not.
Histology--Heme & Lymphoid Neoplasms: Should the higher histology code associated with grade 1 follicular lymphoma [9695/3] be used rather than grade 2 follicular lymphoma [9691/3] in cases of follicular lymphoma grade 1-2?
Code histology to 9691/3 [follicular lymphoma, grade 2], histology. For follicular lymphoma, when there is a grade such as 1-2 indicated, take the histology associated with the higher grade disease process, even though the lower grade histology code is higher.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a 9/30/10 biopsy diagnoses follicular lymphoma, grade 1 and the patient is subsequently diagnosed on a 10/11/10 biopsy with large B-cell lymphoma which is stated to be a transformation of the prior lymphoma?
Per Rule M11, this case is to be accessioned as two primaries; follicular lymphoma, grade 1 [9695/3] and diffuse large B-cell lymphoma (DLBCL) [9680/3]. The case represents a chronic neoplasm (follicular lymphoma, grade) and an acute neoplasm (diffuse large B-cell lymphoma) diagnosed within 21 days of one another and there is documentation of two biopsies, one confirming the chronic disease and the other confirming the acute disease.

2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes.
Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.
