This is a single primary with the histology coded as infiltrating duct and infiltrating lobular carcinoma [8522/3].

For cases diagnosed 2007 or later, the steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules manual. For a breast primary, start with the Breast Multiple Primary Rules because there are site specific rules for breast primaries.

Start at Rule M4 because this patient has multiple tumors in the same breast. The rules are intended to be reviewed in consecutive order within the applicable Module. Abstract a single primary as tumors that are lobular [8520] and intraductal or duct are a single primary.

Use the Breast Histology Coding Rules to determine the correct histology for these multiple tumors abstracted as a single primary. Start at Rule H20 as there were multiple tumors present but it is a single primary. Code the histology to 8522 [duct and lobular] when there is any combination of lobular [8520] and duct carcinoma.

The Note for Rule M10 indicates Table 1 and Table 2 are used to identify specific intraductal and duct carcinomas. Referring to Table 2 (Duct 8500/3 and Specific Duct Carcinomas) note that pleomorphic carcinoma is listed as a specific type of duct carcinoma. Pleomorphic is a word that describes the cellular appearance rather than a specific histology. It is coded when that is the only description/diagnosis given (pleomorphic carcinoma/pleomorphic duct carcinoma). In this case, both duct and lobular are describing the actual histologic types. Ignore the term "pleomorphic" and code the actual histologic descriptors, ductal and lobular. We will make appropriate changes to the breast rules in the MP/H revisions so this distinction is clear.

Code the primary site to C119 [nasopharynx] per Rule PH25.

Per our subject matter expert, use Module 7 Rule PH25 to code the primary site to an organ (nasopharynx and maxillary sinus) because an organ(s) and its regional lymph nodes are involved. The distant lymph nodes are simply part of the staging (the lymphoma has progressed to another lymph node region).

Diffuse large B cell lymphoma originating in the oral cavity and maxillofacial region is rare, but documented. The most common sites for this rare neoplasm are Waldeyer ring, tonsils, nasopharynx, base of tongue, and palatine tonsil. There are also rare cases of diffuse large B cell lymphoma originating in the maxillary sinus. The percentage of cases arising in the nasopharynx is greater than those originating in the maxillary sinus.

Hemophagocytic syndrome, also known as hemophagocytic lymphohistiocytosis (HLH), is not reportable. Per Appendix F, HLH is caused by an over stimulated immune system (infection, etc.). It is a clinical syndrome associated with a variety of underlying conditions. To be reportable, a child's diagnosis must state "fulminant hemophagocytic syndrome" to be reportable (9724/3). This is not the situation in this case.

"Hemophagocytic lymphohistiocytosis" is also listed in Appendix F: Non-Reportable List for Hematopoietic Diseases.

For cases diagnosed 2007 or later, code the primary site to ovary [C56.9] and the histology to papillary carcinoma, follicular variant [8340/3].

The steps used to arrive at this decision are:

Refer to the 2012 SEER Manual for help to determine the primary site. This neoplasm is arising in a teratoma of the ovary. Per the 2012 SEER Manual, in this case the site is coded to ovary [56.9] because that is where the tumor originated. Although the teratoma contains thyroid tissue, it arose in the ovary. Teratomas are unusual in that they contain all three germ cell layers from which an embryo forms. It is not unusual to have malignancies that are usually primary to the thyroid, liver, brain, lung, etc., originate in a teratoma.

Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Other Sites Histology rules because site specific rules have not been developed for this primary.

Start with the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Code the histology as papillary carcinoma, follicular variant [8340/3].

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

Code grade to 6 [B-cell] for the histology malignant non-Hodgkin lymphoma, large B-cell type, with features consistent with T-cell rich variant [9680/3]. Under the Definition section for histology code 9680/3 it states there are morphologic variants of the disease: centroblastic, immunoblastic, plasmablastic, T-cell/histiocyte-rich, anaplastic.

Rule G3 in the Heme Manual confirms the grade listed in the Heme DB under its Grade section for the histology 9680/3. While the patient presented with a variant of DLBCL that is T-cell/histiocyte rich, it is still a B-cell phenotype. The grade is coded accordingly.

Per Rule 18, code the primary site to C775 [pelvic lymph nodes]. Per Rule PH18, code the primary site to the specified lymph node region when the site of lymphoma is described only as a mass. This rule also indicates that the Code pelvic lymph nodes [C775] when the lymph nodes are described as a pelvic mass.

This rule has been effect for SEER for over 20 years. It is based on the fact that a number of lymphomas that originate in nodes are not diagnosed until those nodes become matted or fixed. The presentation is then one of a "mass" in those nodal regions.

Arimidex has not been approved to treat endometrial cancer. It is not prescribed for pre-menopausal women. Clarify with the physician why the drug was being used. If the physician states Arimidex was given to reduce tumor burden, code as hormone therapy.

Code the histology to duct and lobular carcinoma in situ [8522/2].

For cases diagnosed 2007 and later, 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. Start at the MULTIPLE TUMORS Module Rule M4 because the patient had multiple foci of DCIS and a separate, single focus of LCIS. The rules are intended to be reviewed in consecutive order within the applicable Module. Tumors that are lobular and duct are a single primary.

Go to the Breast Histology rules found in the Multiple Primary and Histology Coding Rules Manual. Start at the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY Module Rule H20 because the patient has multiple foci of DCIS and LCIS. Code the histology as 8522/2 [duct and lobular carcinoma in situ] when there is any combination of lobular [8520] and duct carcinoma.

The DCIS and LCIS are separate tumors. The DCIS was removed by the lumpectomy and the LCIS by the mastectomy. The most representative specimen for the DCIS is the lumpectomy. The most representative specimen for the LCIS is the mastectomy. Both pathology reports must be used in this case to determine the histology.

Code the histology as superficial spreading melanoma [8743/3]. For cases diagnosed 2007-2014, the steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules manual. For a melanoma primary, use the Melanoma Histology rules to determine the histology code because there are site specific rules for cutaneous melanomas.

Start at Rule H1. The rules are intended to be reviewed in consecutive order within the applicable Module. Code the most specific histologic term when the diagnosis is melanoma, NOS [8720] with a single specific type, superficial spreading in this case. The subtype of this invasive melanoma is "superficial spreading."

A change will be made to Rule 9 in next update to indicate "growth pattern" can be used to describe an invasive histology.

Per Rule PH30, use the Heme DB to determine the primary site and histology when rules PH1-PH29 do not apply. Code the primary site to C419 [bone, NOS], assuming there are multiple bones involved in this case. If only one bone is involved, code the primary site to the specified bone.

In the Abstractor Notes section in the Heme DB, it indicates the primary site may differ for LCH in the solitary disease and multisystem disease. This patient has multisystem disease with involvement of the bone, liver, spleen and retroperitoneum. The most common sites for multisystem involvement include three of the four above sites (bone, liver, and spleen).

Determine the primary site based on the knowledge of the usual sites of involvement for this disease, the actual sites of involvement for the case presented, and identifying which sites of involvement are likely metastatic and which are the potential primary sites. There are two potential primary sites of involvement: the bone and the retroperitoneum. Bone is a common site of involvement for LCH while the retroperitoneum is not. Code the primary site to C419 [bone, NOS] because multiple bones are involved for this patient and bone is the most common site for LCH based on the documentation in the Abstractor Notes.

The spleen and liver are typically not primary sites for this disease process. They become involved when there is multisystem involvement because they filter the blood. They are typically sites of metastatic involvement. This information will be added to the ABSTRACTOR NOTE section.
