EOD Fields--Lymphoma: Was MALT Lymphoma [9715/3 (ICD-O-2) and 9699/3 (ICD-O-3)] inadvertently excluded from SEER EOD manual, top of page 180?
For cases diagnosed 1998-2003:
Yes. Use the scheme on page 180 for MALT lymphoma. The ICD-O-2 morphology code 9715 was omitted in error. It should have been added when the EOD was printed in 1998.
EOD-Extension--Meninges: How do you code extension for a malignant meningioma that invades into the adjacent brain tissue?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 60. Code 60 is defined as a brain tumor that extends into the meninges. It is also the appropriate code to use for a tumor that extends from the meninges to the brain.
Histology--Breast: Please confirm the morphology code for a diagnosis of "encapsulated papillary carcinoma" of the breast. Several articles on the internet lead me to believe it is the same as an intracystic carcinoma, code 8504/2 (our case shows no evidence of invasion).
You are correct in coding 8504/2 for this case. Per the 4th Edition WHO Tumors of the Breast, encapsulated papillary carcinoma (EPC) of the breast is synonymous with intracystic or encysted papillary carcinoma. It is a variant of ductal carcinoma in situ (DCIS).
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?
Code this case as in situ. The specimen from the excision/resection is the more reliable source for determining behavior, compared to a biopsy, especially in this case where the behavior is ambiguous on the biopsy.
Reportability--Heme & Lymphoid Neoplasms: Does the fact that the Hematopoietic Database states the ICD-O-3 code 9970/1 [Lymphoproliferative disorder/disease, NOS] mean that the ICD-O-3 books should be updated to indicate that as of 2010 the code 9970/1 [Lymphoproliferative disorder/disease, NOS] is no longer applicable?
Lymphoproliferative disorder/disease, NOS [9970/1] is not a reportable neoplasm. There are also new codes that define lymphoproliferative disorder/disease more specifically. If you do a "smart search" and enter only the word "lymphoproliferative" into the Heme DB, you will get a listing of all of the reportable and non-reportable terms. That enables you to look at your record and compare the words in the Heme DB to those in the record you are reviewing.

CS Site Specific Factor--Lymphoma: Can the registrar calculate the International Prognostic Index (IPI) score from information found in the H&P or on the back of a TNM form for the SSF 3 field if the physician does not document it in the medical record?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Record the IPI score in SSF3 when the score is documented in the medical record. If the score is not stated, do not calculate it.
Reportability/Histology--Vulva: Is angiomyxoma (8841/1), such as aggressive angiomyxoma of vulva diagnosed in 2022, reportable?
Do not report superficial angiomyxoma (8841/0) or aggressive angiomyxoma (8841/0). WHO Classification of Female Genital Tumors, 5th edition, defines deep (aggressive) angiomyoma as a benign, infiltrative, myxoid spindle cell neoplasm that occurs in deep soft tissue of the pelviperineal region.
EOD/Summary Stage--Eye: How is stage coded for a patient with extranodal non-Hodgkin lymphoma involving bilateral choroids (single focus, both sites) and no lymph node involvement? Since the eyes are a paired site, is this two separate extranodal sites? If so, there are no Summary Stage or EOD tumor codes that best fit this scenario.
Assign as Stage IV as recommended by our expert hematological oncologist. This is a rare occurrence and this type of presentation does not fit the definition of intraocular extension. Stage IV is probably the best stage for this type of presentation, since there are two extranodal organs involved, even though they involve a bilateral site.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed with small lymphocytic lymphoma in 1996, received chemotherapy on and off for 15 years due to relapses, and was subsequently diagnosed with diffuse large B-cell lymphoma in 2012?
Per Rule M10, this case should be accessioned as two primaries. According to Rule M10, one is to abstract as multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm AND there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis.
The histology for the 1996 chronic neoplasm is coded to 9670/3 [small lymphocytic lymphoma]. The histology for the 2012 acute neoplasm is 9680/3 [diffuse large B-cell lymphoma].
