Code the histology to 9735/3 [plasmablastic lymphoma] and the primary site to C809 [unknown] per Rule PH27.

Code the histology specified when the only histology for the case is preceded by ambiguous terminology. For this case, code the histology to plasmablastic lymphoma because it is the only histology mentioned in the diagnosis.

Per the Heme DB Abstractor Notes section for plasmablastic lymphoma, most patients present with Stage III-IV disease. The positive pleural fluid is likely due to advanced disease. In the absence of any other information for this case, Rule PH27 applies, "Code primary site to unknown primary site C809 when there is no evidence of lymphoma in lymph nodes AND the physician documents in the medical record that he/she suspects that the lymphoma originates in an organ(s) OR multiple organ involvement without any nodal involvement."

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.

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.

Yes, this is a reportable case. The histology is coded to 9962/3 [essential thrombocythemia]. The positive JAK2 mutation testing and bone marrow biopsy results taken together support the diagnosis of essential thrombocythemia in this case.

In the Abstractor Notes section of the Heme DB, it indicates that only 50-60 percent of patients with essential thrombocythemia will have a positive JAK2 mutation. A diagnosis of essential thrombocythemia can still be made in the absence of a JAK2 mutation. For example, if the bone marrow biopsy final diagnosis or a physician's clinical diagnosis is essential thrombocythemia, despite a negative JAK2 mutation test, the neoplasm is still reportable.

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.

Code the primary site to C068 [overlapping lesion of the mouth] per Rule PH24. Code the primary site to the organ when lymphoma is present only in an organ.

This lesion overlaps the left soft tissue of the maxilla (the maxillary gingiva) [C030] and the left vestibule of the mouth [C061]. There is no documentation indicating in which specific site the lesion arose. The maxilla is the upper jawbone. The soft tissue that overlies the maxilla is a part of the oral cavity. It is reasonable to interpret the documentation such that the tumor in the maxilla is an extension of the overlapping oral mucosa tumor.

This is a reportable primary. Langerhans cell histiocytosis (LCH) [9751/3] is a reportable neoplasm.

The term "self-healing" means that the neoplasm regressed without treatment. This is a known phenomenon.

Smoldering multiple myeloma [9732/3] has always been a reportable neoplasm. Per the Abstractor Notes section in the Heme, smoldering multiple myeloma is a variant of multiple myeloma in which the diagnostic requirements for multiple myeloma are met, but there is no organ damage. The patient is usually asymptomatic.

Smoldering myeloma is listed under the Alternate Names section in the Heme DB for multiple myeloma [9732/3] to clarify that it is a reportable neoplasm.

Report all new diagnoses of smoldering multiple myeloma now. Registries are not required to spend time and effort to find these cases if they have not been reporting them in the past. However, report earlier earlier cases if encountered today while performing casefinding or chart review procedures.
