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.

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.

This is a single primary, essential thrombocythemia [9962/3] diagnosed in 2007. The 2010 Heme DB and Manual should not have been used to determine the number of primaries in this case. The Heme DB applies only to cases diagnosed 2010 and later.

In order to determine the number of primaries, use the rules in place at the time of the subsequent 2009 diagnosis of primary myelofibrosis. Per the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, a diagnosis of essential thrombocythemia [9962/3] followed by a diagnosis of primary myelofibrosis [9961/3] is a single primary.

Abstract two primaries for this scenario per Rule M7. The first primary is the renal pelvis in Oct. 2006; the second primary is the ureter in Nov. 2009. The bladder tumor in July 2008 is not a new primary per Rule M8.

Compare the diagnosis date of the current (most recent) tumor to the diagnosis date of the original tumor. This applies even if the patient had six occurrences in-between these dates; you still compare the current tumor to the diagnosis date of the original tumor and ignore recurrences in this process.

Because the site is specifically stated to "skin" of nipple [C44.5], this case is not reportable.

If possible, you may wish to confirm the type of biopsy performed. If the biopsy was done by FNA or needle biopsy, the biopsy tissue should contain a full-thickness of skin and subcutaneous breast (nipple) tissue. If that is the case, this tumor would likely be a reportable squamous cell carcinoma of nipple [C50.0]. If, however, this was a punch biopsy it is more likely a non-reportable squamous cell carcinoma of the skin [C44.5].

For cases diagnosed 2007 or later, accession a single primary, left upper lobe squamous cell carcinoma diagnosed 7/27/2007.

The steps used to arrive at this decision are:

Go to the General Information notes for Determining Multiple Primaries for Solid Malignant Tumors in the Multiple Primary and Histology Coding Rules Manual.

General Information Rule 7 states "Use the multiple primary rules as written unless a pathologist compares the present tumor to the "original" tumor and states that this tumor is a recurrence of cancer from the previous primary."

Accession a single primary. Do not apply the Multiple Primary rules because the pathologist compared the 2007 and 2010 slides and determined this was a recurrence and not a new primary.

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

Amyloidosis, NOS is not reportable. It is listed in Appendix F of the Heme Manual on the Non-Reportable List for Hematopoietic Diseases.

Amyloidosis (AL) is term that refers to a group of conditions that include benign conditions (e.g., found in the pancreas of type II diabetes patients and in the brain lesions of Alzheimer patients) as well as in malignant diseases (e.g., AL found in multiple myeloma and ACal (calcitonin) found in medullary carcinoma of the thyroid). Amyliodosis, NOS is not a term that equates to a malignant diagnosis.

Check the medical record to see if this disease process is designated as either AL or ACal. There should be a malignant diagnosis such as multiple myeloma or medullary carcinoma of the thyroid in such cases rather than simply a diagnosis of amyloidosis. The malignancy needs to be coded, not the symptoms of the disease process.

Code the histology to malignant melanoma, superficial spreading type [8743/3] based on the final diagnosis. 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 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 from Rule H1 to Rule H10. The rules are intended to be reviewed in consecutive order within the applicable Module. Code the more specific histologic term when the diagnosis is melanoma, NOS [8720] with a single specific type (i.e., superficial spreading) mentioned in the final diagnosis.

The final diagnosis takes precedence over the CAP protocol. The CAP protocol may be used when it provides additional or noncontradictory information, but that does not apply in this case.

Mature teratomas in the ovary are benign [9080/0].

For testis, mature teratoma in an adult is malignant (9080/3); however, mature teratoma in a child is benign (9080/0).

With regard to the thyroid issue, from the information above, the medullary carcinoma in the patient's thyroid is clearly a separate event. According to our expert pathologist consultant, "thyroid tissue is one of the many tissue types that may be seen in teratomas. When the teratoma has exclusively or predominantly thyroid tissue the term struma ovarii is used Adenoma or carcinoma of the thyroid type may be seen in this thyroid tissue. If medullary carcinoma were present in the thyroid tissue in the ovary/teratoma, there would be mention of it in the path report."

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

This case is accessioned as a single primary. Code the histology to 9680/3 [diffuse large B-cell lymphoma] and diagnosis date to 2004. Per Rule M2, abstract as a single primary when there is a single histology.
