20051040 Primary Site--Sarcoma: What is the correct topography code for a partial lung lobectomy with pathology diagnosis of "pulmonary sarcoma with smooth muscle differentiation"? See Discussion.

Operative report: palpable 2x2cm mass in the mediastinal surface of the rt middle lobe and the contiguous upper lobe together.

Path comment after partial lung lobectomy: In all likelihood this is a malignant process occurring in smooth muscle changes surrounding vessels within the lung versus an undifferentiated epithelial tumor.

ADDENDUM DX: low grade pulmonary sarcoma with smooth muscle differentiation.

Consultant's report concurs with that of the original pathologist's report of malignant neoplasm compatible with smooth muscle origin.

This case is unique. Assign topography code C493 [Connective, subcutaneous and other soft tissue of thorax]. Based on the information provided, this sarcoma has smooth muscle differentiation and originated in the muscle. Code the primary site to muscle.
20130165 MP/H Rules/Multiple primaries--Thyroid: How many primaries are reported and what is histology for the papillary carcinomas if a Classical cytomorphology with a follicular architecture is on the right and a Columnar cell cytomorphology with a follicular and papillary architecture is on the left? See Discussion.

  • Dominant Tumor: Tumor
  • Laterality: Right lobe
  • Tumor Size: Greatest dimension: 9 cm
  • Histologic Type: Papillary carcinoma
  • Variant, specify: Classical
  • Architecture: Follicular
  • Cytomorphology: Classical
  • Tumor Size: Greatest dimension: 6 cm
  • Histologic Type: Papillary carcinoma
  • Variant, specify: Columnar cell
  • Architecture: Solid, follicular, and papillary
  • Cytomorphology: Columnar cell
  • The answer seems to hinge on whether or not the two tumors differ at the third digit of histology. Can we code the histology based on the terms listed for variant or architecture?

    This is a single thyroid primary. The tumors are both papillary carcinoma with follicular architecture for the most part. Apply Rule M6 and abstract a single primary.
    20071080 First Course Treatment--Liver: Given that agents can be used that are not chemotherapy drugs, how should treatment be coded for a procedure called a "chemoembolization" when the agent used is not documented? This issue was discussed among the national standard setters and per the SEER website this issue has been resolved as follows: When "chemoembolization" is done but the agents used are not chemotherapy drugs, then treatment should be coded as "Other Therapy." See http://seer.cancer.gov/tools/codingmanuals/embolization.html
    20100011 Reportability: Should a benign gangliocytic paraganglioma [8683/0] be considered a reportable (malignant) tumor based on the presence of lymph node metastases? See Discussion. "Resection, periampullary duodenum: Gangliocytic paraganglioma, with metastasis to one large periduodunal lymph node. Six other small lymph nodes negative. COMMENT: The primary tumor in the duodenum is made up mainly endocrine cell component. This component appears to have metastasized to a periduodenal lymph node." This neoplasm is reportable because it is malignant as proven by the lymph node metastases. Code the behavior as malignant (/3) when there are lymph node metastases.

    Laterality--Head & Neck: Does the site code C098 need a laterality code? See Description.

    In the SEER EOD-88 3rd edition, page 36, site code C098 does not need laterality. In the SEER Program code manual, 3rd edition, page 93, site code C098 is listed as a site that needs a laterality code 1-9. Topography code C098 [Overlapping lesion of tonsil] requires a laterality code of 1-9. Follow the laterality guidelines in the SEER Program Code Manual.
    20041007 Other Cancer-Directed Therapy--Hematopoietic, NOS: How is this field coded when transfusions are used to treat acute leukemia or thrombocythemia? Transfusions are NOT recorded as treatment for acute leukemia or thrombocythemia. .
    20061086 Reportability--Melanoma: Is an excisional biopsy of the skin with a diagnosis on the pathology report of "Tumoral melanosis" reportable by itself or must there be a pathologist note, such as "Note: Unless proven otherwise, tumoral melanosis should be considered as a regressed melanoma", in order for it to be considered reportable? See Discussion.

    Skin, left upper back, exc Bx: Tumoral melanosis. Note: Unless proven otherwise, tumoral melanosis should be considered as a regressed melanoma.

    If reportable, do we report a diagnosis of tumoral melanosis without a similar note?

    Tumoral melanosis (TM) alone is not reportable. It is not listed in ICD-O-3. TM can be associated with a regressed melanoma, but it can also occur with other cutaneous tumors. The case is reportable if there is a diagnosis of melanoma.
    20140005 Primary site--Testis: In the absence of a specific statement that the patient's testicle(s) are descended, should the primary site for a testicular tumor be coded as C621 (Descended Testis) when the mass is palpable on physical exam or demonstrated on scrotal ultrasound? See discussion. It seems the non-specific Testis, NOS (C629) code is being over used. Many testis cases have no documentation of the patient's testicular descention. However, testicular tumors in adults are frequently detected by palpation or scrotal ultrasound. An undescended testis (a testis absent from the normal scrotal position) would be non-palpable or not amenable to imaging via a scrotal ultrasound. Unless the testicle is stated to be undescended, it is reasonable to code C621 for primary site. Reserve C629 for cases with minimal or conflicting information.
    20031203 Surgery of Primary Site--Skin: Should this field be coded to 45 [wide excision or reexcision of lesion or minor (local) amputation with margins more than 1 cm, NOS], 46 [with margins between 1 and 2 cm], or 47 [with margins greater than 2 cm] for a skin primary diagnosed in 2003 when margins are stated exactly as 2 cm? Use code 46 [Wide excision...with margins more than 1 cm and less than 2 cm] when margins are exactly 2 cm.

    Surgery of Primary Site--Head & Neck: Is a composite resection performed for an oral cavity primary coded to 40 [Radical excision of tumor, NOS], 41 [Radical excision of tumor only], 42 [Combination of 41 with resection in continuity with mandibles (marginal, segmental, hemi-, or total resection], 43 [Combination of 41 with resection in continuity with maxilla (partial, subtotal, or total resection)]? See discussion.

    Example:

    Patient underwent composite resection of left soft palate, tonsillar fossa, medial pterygoid and lateral tongue for a primary of the retromolar trigone. There was no mention of an excision of the mandible; however, the procedure included the application of a mandibular reconstruction plate.

    Use surgery codes 40-43 for composite resection of an oral cavity primary. In the case example, code Site-Specific surgery as 42 [Combination of 41 WITH resection in continuity with mandible]. Even though excision of mandible was not mentioned, there was mention of a mandibular reconstruction plate. Since the retromolar trigone is ON the mandible, resection of the mandible is likely.
