20130122 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when an excisional biopsy of a chest wall nodule shows diffuse large B-cell lymphoma (40%) and follicular lymphoma, grade 3A (60%)? See Discussion.

The patient presented with a right chest wall nodule. The PET scan showed widespread disease: subcutaneous nodule/mass in the left scalp and right chest wall; large right paraspinal mass; soft tissue density likely a second early paraspinal mass at the right costovertebral junction; right paravertebral mass; and abnormal bony foci in the right humeral head, right iliac crest, right acetabulum and right femur. The physical exam showed 2 cm left supraclavicular lymphadenopathy and a firm 3 cm mass in the right chest wall. Lungs were clear. Abdomen showed no masses or ascites, and no palpable hepatosplenomegaly.

Chest wall nodule excisional biopsy pathology: Lymph node and adjacent soft tissue: Malignant lymphoma with components: 1. Diffuse large B-cell lymphoma (40%). 2. Follicular lymphoma, grade 3A (60%). Pathology report note states the diffuse large cell lymphoma is probably arising from the follicular center cell lymphoma.

Should this be a single primary? There is no mention of cutaneous lymphoma.

Accession a single primary per Rule M4. Code histology to 9680/3 [diffuse large B-cell lymphoma] per Rule PH11.

Per Rule M4, accession a single primary when two or more non-Hodgkin lymphomas are present in the same lymph node or organ.

Per Rule PH11 code the histology to diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow.

Reportability--Brain and CNS: Are the terms 'mass' and 'lesion' reportable terms for accessioning brain and CNS primaries? See Discussion.

With respect to reportability, the SEER Manual mentions 'tumor' and 'neoplasm,' but not 'mass' or 'lesion.' The SEER MP/H Manual states tumor, mass, lesion and neoplasm are equivalent terms for determining multiple primaries, but does this apply to reportability? If not, what is the distinction?

'Mass' and 'lesion' are not reportable terms for benign/borderline brain and CNS tumors.

Reportable terms for benign/borderline brain and CNS primaries are 'tumor' and 'neoplasm.' These terms appear in the ICD-O-3. 'Lesion' and 'mass' do not appear in the ICD-O-3. Do not use the MP/H Manual to determine reportability; page 2 of the SEER Manual is the correct source for reportability instructions.

Multiple primaries/Primary site--Heme & Lymphoid Neoplasms: How many primaries are there and how should I code the primary site(s)? See discussion.

Patient had a hemicolectomy and a salpingo-oophorectomy and was found to have diffuse large B cell lymphoma in the colon (10 cm cecal mass), 3/16 regional lymph nodes involved with lymphoma. Fallopian tube showed involvement with diffuse large B Cell lymphoma.

Multiple primaries - Colon and fallopian tube?

One primary - Colon? Stage IV, or lymphoma from an unknown primary? Note: There were no other lymph nodes involved.

Use Rule M2. Abstract as a single primary when there is a single histology.

When you have questions about how to code the primary site, start with the abstractor notes. If the answer isn't found there go to Module 7 (a specific module to help code primary site for lymphomas).

The abstractor notes for DLBCL in this case do not provide information you can use for this case. Go to Module 7 in the PH rules.

Use Rule PH25 Code the primary site to the organ when lymphoma is present in an organ and that organ’s regional lymph nodes. Code the primary site to colon (organ and regional lymph nodes involved). The fallopian tube is secondary involvement. As is common with lymphomas, there can be more than one organ involved. You can differentiate the primary site from the secondary site(s) because of the large colon mass with regional lymph node involvement.

20130060 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a diagnosis of bilateral extranodal orbital lymphoma when the same histology is present in both orbits?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

This case should be accessioned as a single primary lymphoma of bilateral orbits per Rule M2. Abstract a single primary when there is a single histology. Both orbits showed the same histology. Note 1 for Rule M2 states bilateral involvement of lymph nodes and/or organs is a single primary.

Reportability--Heme & Lymphoid Neoplasms: Is Mast Cell Activation Syndrome (MCAS) reportable?

MCAS has been given an ICD-9 code of 202.60 by our medical record coders. In the Progress Notes, the physicians state this is not the same as systemic mastocytosis. There is no listing for MCAS in the Hematopoietic and Lymphoid Database.

Mast Cell Activation Syndrome (MCAS) is not a reportable neoplasm unless it is specifically stated to be a result of a mast cell proliferative disorder that is reportable.

Per our expert pathologist, MCAS is a relatively new term used for conditions in which patients experience the symptoms of mast cell mediators in the absence of an increase/proliferation of mast cells. The diagnosis of this group of disorders is based in part on a complex of symptoms and on the demonstration of no increase in mast cells. Some of these diseases are difficult to separate from mastocytosis (which is reportable). Currently, this group of disorders is not part of the systemic mastocytosis/mast cell leukemia/mast cell sarcoma spectrum.

20130061 Histology--Heme & Lymphoid Neoplasms: How is the histology coded for "post-transplant lymphoproliferative disorder (diffuse large B-cell lymphoma)"?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the histology to diffuse large B-cell lymphoma [9680/3] per Rule PH1. Code the histology as 9680/3 [DLBCL], the histology of the accompanying lymphoma, when the diagnosis is PTLD and any B-cell lymphoma.

20130149 MP/H Rules/Histology--Testis: What is the histology code for a testis primary with embryonal carcinoma (70%), yolk sac tumor (30%), and a focus of seminoma (<1%)? See Discussion.

The right orchiectomy specimen showed a mixed histology tumor. The retroperitoneal lymph nodes showed teratoma, NOS only. Does the presence of teratoma in the lymph nodes change the histology coding?

The MP/H Rules for Other Sites, Table 2 (Mixed and Combination Codes) does not include the combination of embryonal carcinoma, yolk sac tumor and seminoma. SINQ 20110013 does state the combination of embryonal carcinoma and yolk sac tumor should be coded to histology 9065/3 [germ cell tumor, nonseminomatous]. In this case, is the focus of seminoma comprising <1% included when coding the histology? If the seminoma is included, Table 2 still does not address this combination.

Code the histology to mixed germ cell tumor [9085/3] per Rule H16; code the appropriate combination/mixed code when there are multiple specific histologies.

According to the WHO Classification of Tumors of the Male Genital Organs, tumors of more than one histologic type (mixed forms) can occur in any combination of various germ cell histologies including embryonal, yolk sac, teratoma, and choriocarcinoma. Mixed teratoma and seminoma is included under histology code 9085/3 [mixed germ cell tumor] in the ICD-O-3. The revised MP/H rules will expand on these mixed testicular histologies.

Priority for coding histology is using the diagnosis from the primary site (when possible) over the histology from a metastatic site. The presence of teratoma, NOS in the retroperitoneal lymph nodes does not change the histology code.

MP/H Rules/Histology--Head & Neck: How is the histology coded for a mammary analogue secretory carcinoma (MASC) of the parotid gland? See Discussion.

There is no histology listed in the ICD-O-3 for a mammary analogue secretory carcinoma. The pathologist stated that, "MASC is a recently described salivary gland tumor type which, as the name implies, resembles secretory carcinoma of the breast." Should the histology be coded 8550/3 [acinar carcinoma] or 8502/3 [secretory carcinoma of breast]?

Assign code 8502/3 [secretory carcinoma of breast].

Acinar carcinoma [8550/3] describes a very typical type of salivary gland tumor only. This histology code does not adequately capture the histology in this case which describes a secretory carcinoma that is similar to mammary cancer. Both of these elements are reflected in the histology code 8502/3 [secretory carcinoma of breast].

20130179 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries and what is the histology for each primary if a diffuse large B-cell lymphoma [9680/3] and a focus of splenic marginal zone lymphoma [9689/3] occur in a splenectomy specimen? See Discussion.

Patient presents with a huge mass in the spleen with direct extension to gastric fundus.

12/1/12 Splenectomy: Macroscopic nodules compatible with diffuse large B-cell lymphoma [9680/3]. Further, in the white pulp there are changes compatible with focus of splenic marginal zone lymphoma [9689/3].

Under the Transformations To section in the Heme DB, splenic marginal zone lymphoma transforms to diffuse large B-cell lymphoma.

Per Rule M4, this is a single primary. According to Rule M4, one is to abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s).

Per Rule PH11, code the histology to 9680/3 [diffuse large B-cell lymphoma] and the primary site to C422 [spleen]. According to PH11, one is to code the primary site to the site of origin, lymph node(s), lymph node region(s), tissue(s) or organ(s) and histology to diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow.

20130131 Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded, and which PH rule applies, when chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is diagnosed simultaneously by biopsies of both lymph node(s) and the bone marrow?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the primary site to C421 [bone marrow] per Rule PH5 when CLL/SLL [9823/3] involves the bone marrow.

In the later stages of CLL/SLL, there may be involvement of bone marrow AND lymph node(s), lymph node region(s), organ(s), or tissue(s). As long as the peripheral blood and/or bone marrow are involved, the primary site is bone marrow.

WHO states that the diagnostic criteria for CLL versus SLL is not clearly defined. According to WHO guidelines, it is better to code to CLL/SLL and code the primary site to bone marrow when the marrow is involved and to lymph nodes, organ, or tissue when there is no bone marrow involvement.
