20130043 | Reportability--Heme & Lymphoid Neoplasms: Is reactive plasmacytosis a reportable diagnosis that is equivalent to plasmacytoma? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Reactive plasmacytosis is not reportable unless there is another indication of a reportable neoplastic disease. Reactive plasmacytosis is "a well known pathological process described as occurring in a variety of situations including infections, autoimmune disease, diabetes mellitus, sideropenia, liver cirrhosis and neoplastic conditions including leukemia. This process, by definition, is assumed to be a reaction of the immune system to an unknown or poorly defined stimulus." Based on this definition, reactive plasmacytosis is not the same as a plasmacytoma, although it may indicate the presence of a neoplastic process, such as leukemia.

20130106 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2009 diagnosed Hodgkin lymphoma, nodular sclerosis type is treated and subsequently presents in 2010 with the same diagnosis? See Discussion. | 2009 diagnosis of Hodgkin lymphoma, nodular sclerosis type involved the superior mediastinal nodes, AP window nodes, bilateral axillary nodes and pulmonary nodules. The patient received chemotherapy and went into remission.
Patient presents in 2010 with Hodgkin lymphoma, nodular sclerosing type in the superior mediastinum.
Does timing play any part in determining if this reported as one or two primaries? There is no timing rule in the Heme Manual. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Accession a single primary, Hodgkin lymphoma, nodular sclerosis type [9663/3] diagnosed in 2009 per Rule M2.
Accession a single primary when there is a single histology. Note 2 for Rule M2 indicates timing is not relevant. This is disease progression or recurrence and not a new primary.

20130193 | Sex: How is sex coded for a transsexual diagnosed with a testicular primary? See Discussion. | The Physical Exam states patient is male. There is a note that the patient is transsexual. There is no indication that the orchiectomy was part of gender reassignment surgery. | Code sex to 1 [male]. When the natal sex is known, code that over transsexual. | 2013 |

20130148 | Reportability--Brain and CNS: Are "spinal" schwannomas reportable if stated to be extradural, vertebral nerve sheath, or of specific vertebrae? See Discussion. | Are any of the following cases reportable?
Example 1: Clinical Diagnosis: Extradural spinal cord tumor compatible with schwannoma. What assumptions should be made about reportability if the tumor is described as being extradural? The extradural spinal cord includes epidural fat surrounding the thecal sac and exiting nerve roots. Does this mean there are not nerve roots in the extradural spinal cord?
Example 2: Final Pathologic Diagnosis: Designated "C3-4 nerve sheath tumor" excision: Morphologic and immunohistochemical findings consistent with cellular schwannoma. When stated to be a "nerve sheath tumor" does that mean peripheral nerve (C47_) involvement or nerve root (C72_) involvement?
Example 3: Final Pathologic Diagnosis: T-8 vertebral tumor resection: Schwannoma with degenerative changes (calcification, cyst formation) - ganglion and nerve are identified. There is no mention clinically or pathologically whether this tumor is "intradural" or "of the nerve root." In the absence of information about whether the location of the tumor is intradural or involving the nerve root, is it assumed that it does involve this part of the spinal cord when a specific vertebrae is removed? |
Extradural schwannomas are not reportable. Neither vertebral nerve sheath nor a location of/on a specific vertebrae confirm the origin as being either extradural or intradural. Do not report a schwannoma if it cannot be determined to be "intradural" or "of the nerve root." | 2013 |

20130149 | MP/H Rules/Histology--Testis: What is the histology code for a testis primary with embryonal carcinoma (70%), yolk sac tumor (30%), and a focus of seminoma (<1%)? See Discussion. | The right orchiectomy specimen showed a mixed histology tumor. The retroperitoneal lymph nodes showed teratoma, NOS only. Does the presence of teratoma in the lymph nodes change the histology coding?
The MP/H Rules for Other Sites, Table 2 (Mixed and Combination Codes) does not include the combination of embryonal carcinoma, yolk sac tumor and seminoma. SINQ 20110013 does state the combination of embryonal carcinoma and yolk sac tumor should be coded to histology 9065/3 [germ cell tumor, nonseminomatous]. In this case, is the focus of seminoma comprising <1% included when coding the histology? If the seminoma is included, Table 2 still does not address this combination. |
Code the histology to mixed germ cell tumor [9085/3] per Rule H16; code the appropriate combination/mixed code when there are multiple specific histologies.
According to the WHO Classification of Tumors of the Male Genital Organs, tumors of more than one histologic type (mixed forms) can occur in any combination of various germ cell histologies including embryonal, yolk sac, teratoma, and choriocarcinoma. Mixed teratoma and seminoma is included under histology code 9085/3 [mixed germ cell tumor] in the ICD-O-3. The revised MP/H rules will expand on these mixed testicular histologies.
Priority for coding histology is using the diagnosis from the primary site (when possible) over the histology from a metastatic site. The presence of teratoma, NOS in the retroperitoneal lymph nodes does not change the histology code. |

20130055 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a lymphoma with multifocal bone and epidural involvement but no lymph node involvement if the physician does not clearly state the primary site? See Discussion. | MRI Lumbar spine: Bony metastatic disease most evident at L5, L3 and T10. There is marrow tumor in the posterior elements of T12 and T10. The 14 mm epidural mass represents epidural tumor, likely metastatic, extending into the left intervertebral foramen at T12-L1.
PET scan: Hypermetabolic activity corresponding to epidural mass at the level of T12 and L1 concerning for malignancy. Other small areas of hypermetabolic activity in the left mandible and both femoral necks. There is no hypermetabolic activity corresponding to the areas of abnormal marrow edema in the vertebral bodies which enhanced on MRI scan in the lumbar and lower thoracic spine. No lymph nodes mentioned.
Biopsy epidural mass: Diffuse large B-cell lymphoma with a background of follicular lymphoma, consistent with a large cell transformation. Flow cytometry confirms a mixed large and small cell population of lymphoma (55% large cells).
T12/L1 Bone Biopsy: Bone and marrow with atypical paratrabecular lymphoid infiltrates, suspicious for involvement by follicular lymphoma. Negative for large cell lymphoma. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site of the diffuse large B-cell lymphoma [9680/3] to C809 [unknown primary site] per Rule PH27. The patient has involvement of multiple bones and an epidural mass with no evidence of nodal involvement. Code the primary site to unknown [C809] when multiple organs are involved without any lymph node involvement, even when there is no statement from the physician regarding primary site.

20130065 | Histology--Heme & Lymphoid Neoplasms: Should the higher histology code associated with grade 1 follicular lymphoma [9695/3] be used rather than grade 2 follicular lymphoma [9691/3] in cases of follicular lymphoma grade 1-2? | Code histology to 9691/3 [follicular lymphoma, grade 2], histology. For follicular lymphoma, when there is a grade such as 1-2 indicated, take the histology associated with the higher grade disease process, even though the lower grade histology code is higher. | 2013 | |
|
20130107 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded for a diagnosis of polycythemia vera with myeloproliferative syndrome? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9950/3 [polycythemia vera], the more specific histology, per Rule PH29. Myeloproliferative syndrome is a non-specific (NOS) histology and polycythemia vera is a specific type of myeloproliferative disease.

20130222 | MP/H Rules/Histology--Bladder: How is the histology coded for a single bladder tumor showing invasive urothelial carcinoma with extensive divergent differentiation including small cell carcinoma, micropapillary carcinoma, and squamous cell carcinoma features? See Discussion. | MP/H rules seem to lead to Rule H8 which indicates that one use the numerically higher ICD-O-3 code. If one applies Rule H8, the histology is coded to 8131/3 [micropapillary urothelial carcinoma]. That would ignore the small cell carcinoma, which seems prognostically more significant. | Code the histology to 8045/3 [mixed small cell carcinoma], a combination of small cell with other types of carcinoma. There is currently no rule in the urinary site MP/H Rules for this combination of histologies. This will be included in the next revision of the MP/H Rules. | 2013 |
