Under the Alternate Names section of the Heme DB, systemic mastocytosis with Associated Clonal Hematological Non-Mast Cell Lineage Disease (SM-AHNMD) is a synonym for systemic mastocytosis. Per Rule M2, this is one primary. Abstract a single primary when there is a single histology. Code the histology to 9741/3 [systemic mastocytosis].

Per the pathology report, the two diagnoses of systemic mastocytosis and mantle cell lymphoma meet the criteria for SM-AHNMD. The B-cell lymphoma is a symptom/marker of the AHNMD. In systemic mastocytosis with AHNMD, a myeloid or lymphatic malignancy is diagnosed with the SM. The prognosis is usually dominated by the non-mast cell malignancy.

Code the histology to diffuse large B-cell lymphoma [9680/3] because the physician states this is a DLBCL and is treating the patient accordingly. Although the pathology report was only compatible with DLBCL, there was a subsequent clinical diagnosis that confirmed a diagnosis of DLBCL. In addition, the patient was treated for DLBCL.

For cases diagnosed 2007 or later, the correct histology code is 8244/3 [composite carcinoid]. The steps used to arrive at this decision are:

Step 1: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Colon Histology rules because site specific rules have been developed for this primary.

Step 2: Start at the SINGLE TUMOR module, rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at rule H9. Code the histology as 8244/3 [composite carcinoid] when the diagnosis is adenocarcinoma and carcinoid tumor.

Neuroendocrine tumor, grade 1 (G1) is synonymous with carcinoid tumor [8240/3] for the purpose of rule H9.

If the bone is involved, code the primary site to bone. Langerhans more commonly starts in the bone and extends to the soft tissue.

If bone is not involved, code primary site to C492, Connective, subcutaneous and other soft tissues of lower limb and hip.

This case is not reportable. Neither plasma cell dyscrasia nor MGUS are reportable. Smoldering myeloma was given as a possible diagnosis, but never confirmed.

Per Rule M10, abstract two primaries. Per the Heme DB, polycythemia vera [9950/3] transforms to an acute myelogenous leukemia [9861/3]. According to Rule M10, one is to abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm (e.g., polycythemia vera) AND there is a second diagnosis of an acute neoplasm (e.g., acute myelogenous leukemia) more than 21 days after the chronic diagnosis.

For cases diagnosed 2018 and later

HGSIL of the vulva or vagina is reportable. HGSIL is a synonym for squamous intraepithelial neoplasia, grade III.

Per Rule M3, abstract a single primary when a sarcoma (myeloid sarcoma) is diagnosed either simultaneously or after a leukemia of the same lineage (acute myeloid leukemia). Per the notes for Rule M3, the sarcoma is a solid manifestation of the associate leukemia.

Per PH10, code the histology to 9861/3 [acute myeloid leukemia] and the primary site to C421 [bone marrow]. PH10 states one is to code the primary site bone marrow (C421) and code the histology acute myeloid leukemia, NOS (9861/3) or any of the specific AML histologies (9840/3, 9865/3-9867/3, 9869/3-9874/3, 9891/3, 9895/3-9898/3, 9910/3, 9911/3 and 9931/3) when the diagnosis is myeloid sarcoma (9930/3) AND there is a simultaneous or previous diagnosis of acute myeloid leukemia.

Code the primary site to C419 [bone, NOS] per Rule PH30.

This patient has widely metastatic disease. Per Rule PH30, one needs to reference the Heme DB to determine the primary site and histology for this case. Per the Abstractor Notes section, Langerhans cell histiocytosis arises in the bone and many times can involve multiple bones, along with other organs and lymph nodes. Although the right femur was biopsied, this does not prove that the primary site is the femur [C402] because the patient has what was described as extensive bony metastatic disease.

Hyalinizing trabecular neoplasm is not reportable.

Hyalinizing trabecular neoplasm, or hyalinizing trabecular tumor, is a synonym for hyalinizing trabecular adenoma [8336/0] in the ICD-O-3. The 2004 WHO classification states that "fine needle aspiration biopsy is often interpreted as papillary carcinoma because of the nuclear features in the tumor."
