20091083 | Grade/Cell indicator--Lymphoma: How is Grade/Cell indicator coded for anaplastic large cell lymphoma? See Discussion. | The SPCM states cell indicator codes take precedence over grade/differentiation codes for lymphoma and leukemia cases. | For cases diagnosed prior to 1/1/2010:Because there is no cell indicator information, code 9 [cell type not determined] in the grade/cell indicator field. Do not code grade for lymphoma. For lymphoma and leukemia this field is the cell indicator. For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20091065 | Primary Site/CS Extension--Lymphoma: How are these fields coded for a non-Hodgkins lymphoma case with scans that show non-specific parenchymal lung nodules and a large mediastinal mass? See Discussion. |
Patient presented with large bulky mediastinal mass. CT showed no pleural effusion. Findings also show non-specific parenchymal lung nodules. Biopsy of mediastinal mass showed malignant B-cell lymphoma of follicle center cell origin. Abdomen /Pelvis CT showed borderline lymph nodes in bifurcation. Clinical diagnosis was probable stage 3 if not 4 lymphoma. Per lymphoma guidelines, if extra-nodal primary site is assigned to the extranodal site if an extra-nodal site and its regional lymph nodes are involved. Would the parenchymal lung nodules be indicative of pulmonary involvement? If so, would primary site be lung? Or, would the parenchymal nodules be stage 4 disease and primary site be assigned to lymph nodes? |
For cases diagnosed prior to 1/1/2010, this answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2. Code Primary Site to C779 [Lymph node, NOS]. In this case, there is no statement that lymphoma involves the lung. "Nonspecific parenchymal lung nodules" are not indicative of lymphoma involvement. Consequently, this cannot be assumed to be an extra-nodal lymphoma. Additionally, it is not clear whether or not the "borderline" pelvic lymph nodes are involved. If the physician cannot provide more information, follow instruction 4.e in the SEER manual on page 72. For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20091100 | MP/H Rules/Histology--Melanoma: How is histology coded for a "melanoma in situ, lentiginous type," arising in the skin of the lower leg? See Discussion. |
In researching this, acral lentiginous melanoma is observed on the palms, soles and under the nails. To code to 8744, do we specifically have to see the word "acral" lentiginous melanoma? |
For cases diagnosed 2007 to 2020 Assign 8742/2 [lentigo maligna] to "melanoma in situ, lentiginous type." Acral lentiginous melanoma is not the same as melanoma, lentiginous type. "Acral lentiginous melanoma," 8744, should be used only if the report states acral lentiginous melanoma or malignant melanoma, acral lentiginous type. Acral lentiginous melanoma most often occurs on the soles of the feet or the palms of the hands. |

20091047 | MP/H Rules/Histology--Ovary: How is histology coded for "serous carcinoma, papillary invasive pattern"? | For cases diagnosed 2007 or later, code the histology 8441/3 [Serous carcinoma, NOS]. Use the Other Sites rules. Start with rule H8 and stop at rule H11. "Pattern" is not one of the terms used to identify a specific type (See H16), so papillary is ignored. | 2009 | |
|
20091076 | Surgery of Primary Site/Scope Regional LN Surgery--Breast: How should these fields be coded when a sentinel lymph node dissection removes one-to-three axillary lymph nodes and a total/simple mastectomy is done? | Assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast] for Surgery of Primary Site. Assign code 2 [Sentinel lymph node biopsy] for Scope of Regional Lymph Node surgery. Code 41 applies to a total/simple mastectomy with any number of sentinel lymph nodes removed -- as long as all of the nodes removed are designated as sentinel nodes. | 2009 | |
|
20091060 | MP/H Rules/Multiple Primaries--Head and Neck: How many primaries are to be accessioned for a case in which a second tumor occurs in an area previously involved by direct extension from a prior primary located in an adjacent site? See Discussion. | Patient diagnosed in August 2007 with squamous cell carcinoma in the right tonsil. This tumor extended to the base of tongue. Treatment consisted of radiation and chemotherapy. In May 2008, the patient was found to have squamous cell carcinoma of the base of tongue. How many primaries are to be accessioned for this case? Rule M7 states that tumors in sites with ICD-O topography codes that are different at the second or third character are multiple primaries. The topography code for base of tongue differs from that of tonsil. Would rule M7 apply? On the other hand, the base of tongue was involved by the tonsil primary which was diagnosed less than one year before. | For cases diagnosed 2007 or later: The May 2008 diagnosis is not a new primary. Base of tongue involvement was originally present in August 2007. The May 2008 diagnosis does not represent new tumor. The 2007 rules apply to new tumors only; therefore, the 2007 rules do not apply to this case. |

20091009 | MP/H Rules/Histology--Kidney: How do you code histology for a renal cell carcinoma when pathologists disagree as to whether or not the tumor is consistent with thyroid-like follicular carcinoma of the kidney? See Discussion. | Final diagnosis states 'left radical nephrectomy, renal cell carcinoma.' The CAP Histologic Type is listed as: Unclassified, most consistent with primary thyroid-like follicular carcinoma of the kidney.' Because of the unusual histology it was sent for a consult to a genitourinary pathology specialist. His response was: 'histologic features not typical for any of the known subtypes of renal cell carcinoma and are not consistent with primary thyroid-like follicular carcinoma of the kidney, a distinct renal tumor that we have recently published in the literature.' The tumor was TTF-1 negative, arguing against metastasis from a thyroid primary. | For cases diagnosed 2007 or later, assign code 8312 [renal cell carcinoma, NOS]. The diagnosis is renal cell carcinoma, but the specific type is in question. | 2009 |
|
20091072 | Histology--Brain and CNS: How is histology coded for a "rosette-forming glioneuronal tumor" of the fourth ventricle? | Assign histology code 9505/1 [Ganglioglioma, NOS].
Rosette-forming glioneuronal tumor of the 4th ventricle is a new WHO entity. There is no current ICD-O-3 code for this. The best code available at this time is 9505/1. |

20091129 | Primary Site--Breast: What subsite is to be coded for a case of invasive Paget disease of the nipple with an infiltrating ductal carcinoma of the lower inner quadrant? | Code C50.9 [Breast, NOS]. Code the last digit of the primary site to '9' for single primaries when multiple tumors arise in different subsites of the same anatomic site and the point of origin cannot be determined. Nipple [C50.0] and LIQ [C50.3] fit this rule. This is a single primary per MP/H Breast Rule M9. | 2009 | |
|
20091014 | MP/H Rules/Histology--Melanoma: Please clarify what we should code when we see the term 'spitz or spitzoid' in association with melanomas. See Discussion. |
Path reports often diagnose "melanoma with spitzoid features." There is no code for this in ICD-O-3. Would it be melanoma NOS with a specific type for MP/H rule H9 (with features of...), or would we stop at H3? Could the matrix principle apply, changing 8770/0 (one of the synonyms is Spitz nevus) to 8770/3 (although no Spitz synonyms are specifically listed under this code)? What if the path report says "melanoma arising in a Spitz nevus"? |
For cases diagnosed 2007 - 2020 Assign code 8720/3 [Malignant melanoma] for melanoma with Spitzoid features, Spitzoid variant of nevoid melanoma, melanoma arising in Spitz nevus, or Spitzoid melanoma. The WHO Classification of Tumors groups these with Nevoid melanomas and codes them to 8720/3. According to WHO, "Nevoid melanoma is a subtype of malignant melanoma of the skin that is distinctive in that the primary lesion mimics many of the architectural features of a common compound or intradermal nevus ... or a Spitz nevus... These lesions are defined not as atypical nevi, but as melanomas because they involve the dermis and have the potential for metastasis." |
