Reportability/Primary Site--Head & Neck: If a wedge resection/shield resection is performed on the lower lip for SCCA and the path report refers to "lip, NOS" with no mention of vermilion border, is this case reportable?
Review the operative and pathology reports, and the physical exam for mention of "mucosal surface" (reportable) or "skin" (not reportable). If neither are mentioned, lip, NOS is reportable per the ICD-O-3 code of C009.
Reportability/Behavior Code--Soft Tissue: Is a final diagnosis of a forearm mass diagnosed as "Angiomatoid malignant fibrous histiocytoma [see note]" reportable? The NOTE reads "Angiomatoid malignant fibrous histiocytoma is a low grade borderline lesion with a tendency for local recurrence, but a very low potential for distant metastases." Is behavior /1 or /3?
Angiomatoid malignant fibrous histiocytoma is reportable with a behavior code of /3 according to ICD-O-3. The Final Diagnosis takes precedence over the "note."
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.
Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned when a patient was diagnosed in 2003 with malignant lymphoma, mixed cell type, follicular in the inguinal lymph nodes and was recently diagnosed with follicular lymphoma (by a neck lymph node biopsy) involving the neck and mediastinal lymph nodes?
This case should be accessioned as a single primary: malignant lymphoma, mixed cell type, follicular [9691/3] diagnosed in 2003. The following describes how this determination was made.
This case is one in which the terminology for follicular lymphoma has changed over time. In 2003, follicular lymphoma was classified as small cleaved cell, large cell, or mixed cell (both small cleaved and large cell). Those designations are no longer used. This disease process is currently classified as follicular lymphoma NOS, grade 1, grade 2 or grade 3. The change was simply a change in classification/terminology.
Appendix A, Table A3 (Obsolete Terms as Defined in ICD-O-3, Lymphoid Neoplasm Obsolete Terms) should be used to determine the current term when an obsolete term is known/given. Per the Table, "Mixed cell type follicular lymphoma" is currently known as "Follicular lymphoma, grade 2" and the correct histology code is 9691/3. This is the correct histology for the 2003 primary.
Per Rule M15, the histologies must be check in the Multiple Primaries Calculator to determine the number of primaries. Enter [follicular lymphoma, grade 2 (malignant lymphoma, mixed cell type, follicular)] for Histology Code 1 and [follicular lymphoma, NOS] for Histology Code 2. The result is "Same Primary." As a result, accession a single 2003 diagnosed primary with the histology follicular lymphoma, grade 2 [9691/3] when the patient is subsequently diagnosed with follicular lymphoma, NOS.

Behavior Code--Bladder/Lymphoma: Should the "in situ" designation on a bladder primary's pathology report be ignored that states a diagnosis of "in situ lymphoma"?
Ignore the in situ designation. You cannot assign an in situ behavior code to a lymphoma primary. The term or designation of "in situ" is limited to solid tumors; carcinoma and/or cancer.
Reportability/Behavior: Is HGSIL (high grade squamous intraepithelial lesion) of the vulva or vagina reportable and is it a synonym for histology code 8077/2 [squamous intraepithelial neoplasia, grade III]?
For cases diagnosed 2018 and later
HGSIL of the vulva or vagina is reportable. HGSIL is a synonym for squamous intraepithelial neoplasia, grade III.
Primary site--Kidney, renal pelvis: Should primary site be coded C809 [unknown] or C649 [kidney] when a patient is diagnosed with renal cell carcinoma in a transplanted kidney?
Code the primary site to C649 [kidney]. Per the SEER Manual, code the site where the neoplasm originated. There are no separate instructions for coding primary site for transplanted organs. This patient's renal cell carcinoma originated in the kidney [C649].
MP/H Rules/Histology--Prostate: What is the histology code for a prostate case whose histology reads “adenoca with mixed ductal and acinar variants?
Assign 8523/3.
The 2013 revision to ICD-O-3 has a new code for mixed acinar ductal carcinoma; however, this new code will not be implemented in the U.S. until 2018 or later. Page 7 of the Guidelines for ICD-O-3 Update Implementation document released by NAACCR 1/1/2014 instructs us to use 8523/3 in the meantime.
