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.
MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned when a pathology specimen reveals one tumor with invasive mucinous carcinoma [8480/3] and a second tumor with in situ ductal carcinoma, solid and cribriform types [8523/2]?
For cases diagnosed 2007 or later, accession two primaries, invasive mucinous carcinoma [8480/3] and in situ ductal carcinoma, solid and cribriform types [8523/2].
The steps used to arrive at this decision are:
Go to the Breast MP rules found in the Multiple Primary and Histology Coding Rules Manual after determining the histology of each tumor (8480/3 and 8523/2).
Start at the MULTIPLE TUMORS module, rule M4. These tumors have ICD-O-3 histology codes that are different at the second (xxx) and third (xxx) number and are, therefore, multiple primaries.
Reportability--Skin: Is atypical intradermal smooth muscle neoplasm (AISMN) of the skin reportable? The comment on the path report states: Atypical intradermal smooth muscle neoplasm (AISMN) was previously termed "cutaneous leiomyosarcoma."
Atypical intradermal smooth muscle neoplasm (AISMN), previously termed "cutaneous leiomyosarcoma," is not reportable. It is classified as a borderline, /1, neoplasm.
EOD-Clinical Extension--Prostate: How is this field coded when biopsies of the prostatic apex are positive and the physician clinically stages the case as T1c?
For cases diagnosed 1998-2003:
Code clinical extension to 33 [arising in the prostatic apex] when a biopsy of the prostatic apex is positive for malignancy, with no further evidence of involvement. If biopsies of both the apex and another site within the prostate (for example right lobe) are positive and there is no mention that the malignancy arose in the apex, code extension to 34 [extending into the prostatic apex].
Histology (Pre-2007)--Prostate: What code is used to represent the histology "adenocarcinoma, cribriform type"?
For tumors diagnosed prior to 2007:
Code the Histology field to 8201/3 [cribriform carcinoma]. The word "type" is a term that indicates majority of the tumor. The term "cribriform" would be a term used to determine the histology code.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported for a patient with a 6/5/12 RUL biopsy that is positive for MALT lymphoma and a 6/7/12 cervical lymph node biopsy that is positive for follicular lymphoma?
Per Rule M15, abstract two primaries for this case. According to M15, use the Heme DB Multiple Primaries Calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. The result is two primaries, MALT lymphoma [9699/3] and follicular cell lymphoma [9690/3].
SEER*Educate provides training on how to use the Heme Manual and DB.

Reportability--Skin: Effective 2021, a cutaneous leiomyosarcoma is a related term for smooth muscle tumor, NOS (8897/1) in ICD-O-3.2. Currently, we have been capturing these as a C44_ (leiomyosarcoma, 8890/3) but the 2019 SEER inquiry states that atypical intradermal smooth muscle neoplasm (AISMN) was previously termed cutaneous leiomyosarcoma. This is not documented on the 2018 ICD-O-3 updates. Should this 2019 case be 8897/1 or 8890/3?
Cutaneous leiomyosarcoma is reportable for 2019. Code histology to leiomyosarcoma 8890/3.
As of cases diagnosed 1/1/2021, it is no longer reportable based on assignment to 8897/1 in ICD-O-3.2.
Reportability/Terminology--Head & Neck: Is an "evolving" squamous cell carcinoma of the vermillion border of the left lower lip reportable?
For solid tumors, ignore the term "evolving" and apply the registry rules for reportability to this case. Squamous cell carcinoma of the vermillion border of the lower lip (C001) is reportable.
