Code the behavior to /3 [malignant, invasive].

"Stromal invasion" means the cancer is invasive. "Stroma" is the supporting connective tissue around and between ducts. It is outside the duct basement membrane. If the tumor cells extend into the stroma, the proper behavior designation for the tumor is invasive.

When there is a question of whether the SEER MP/H Rules or Hematopoietic and Lymphoid Neoplasm Rules apply, check the histology and refer to the Case Reportability Instructions in the Hematopoietic and Lymphoid Neoplasm Manual. All ICD-O-3 morphology codes in the range 9590 - 9992 are included in the Hematopoietic Rules. Mycosis Fungoides [9700/3] is included in this range. Therefore, the SEER MP/H Rules do not apply to mycosis fungoides.

This case should be accessioned as a single primary: mycosis fungoides [9700/3] of the skin, NOS [C449]. Per Rule M2 abstract a single primary when there is a single histology.

Note that in the Primary Site(s) section of the Heme DB, it states the primary site must always be coded to skin (C440 - C449) for mycosis fungoides. Because the primary site is stated in this section of the Heme DB, it is not necessary to use the Primary Site Rules to determine the primary site. Code the primary site to C449 [skin, NOS] because the patient has multiple sites of skin involvement and there is no documentation indicating which subsite of skin was the origin of the mycosis fungoides.

The behavior code for hemangioblastoma can be coded to /3 when a pathologist indicates that the behavior is malignant. The behavior code should be based on a pathologist's opinion. It is usually not possible for a radiologist or patient care physician to make this determination clinically.

The histologic appearance of hemangioblastoma may resemble metastatic renal cell carcinoma; therefore, one will often see renal cell carcinoma listed as a possible diagnosis. This does not indicate that the hemangioblastoma is malignant. Do not code the behavior as /3 based on a differential diagnosis of renal cell carcinoma.

This case should be accessioned as two primaries per Rule M15. Rule M15 instructs one to 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. Code the histology for the 1999 primary to 9687/3 [Burkitt high grade B cell lymphoma] and code primary site to C739 [thyroid.] Code the second primary to 9680/3 [diffuse large B-cell lymphoma] with primary site coded to C079 [parotid gland] per Rule PH24 which instructs one to code the to the when lymphoma is present only in an .

According to the MP/H rules, code histology to 8010/2 [intraepithelial carcinoma] for cases diagnosed 2007-2014. Borderline mucinous tumor is not reportable to SEER.

The steps used to arrive at this decision are:

Go to the Other Sites Histo rules found in the Multiple Primary and Histology Coding Rules Manual.

Start at the SINGLE TUMOR: IN SITU ONLY module, rule H1. Code the histology when only one histologic type is identified. The only reportable histology in this case is intraepithelial carcinoma [8010/2].

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

Macrocytic anemia is not reportable. Anemia refers to a condition of having a low count of red blood cells. The term "macrocytic" refers to the enlarged size of the red blood cells. Macrocytic anemia is usually caused by vitamin deficiencies, alcohol use, medications or thyroid disorders.

Do NOT use the Collaborative Stage Manual to determine the histology code. For CS STAGING purposes only, coding should be based on the squamous cell carcinoma component of this tumor.

The Multiple Primary and Histology Coding Rules Manual is the correct source for coding histology. For cases diagnosed 2007 or later, the following steps are used to determine the histology code:

Open the Multiple Primary and Histology Coding Rules manual. For an esophagus primary, use the Other Sites Histo rules to determine the histology code because esophagus does not have site specific rules.

Start at Rule H8 because this is an invasive histology (assuming this is a single tumor). which states that one should code the appropriate combination/mixed code from Table 2 when there are multiple specific histologies.

Find Other Sites for Table 2 under the Terms & Definitions section of manual.

Locate the appropriate mixed code for squamous cell carcinoma and adenocarcinoma in column 1. Per column 3, the correct histology is adenosquamous carcinoma. Per column 4, the correct histology is 8560/3.

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

Common variable immunodeficiency (acquired hypogammaglobulinemia) is not a reportable condition.

Common variable immunodeficiency represents a group of approximately 150 primary immunodeficiencies that have a common set of symptoms but different underlying causes, both benign and malignant.

The case is not reportable unless this immunodeficiency diagnosis is accompanied by a diagnosis of a cancer or a reportable hematopoietic or lymphoid neoplasm.
