Reportability: Are malignant tumors of genital skin reportable? On page 1 of the 2004 SEER Manual, Reportable Diagnoses, 1.b.i. Exceptions: malignant and invasive histologies not required by SEER - Skin. There is no longer a note that states that lesions ARE reportable for skin of the genital sites. Has SEER discontinued the collection of malignant skin tumors of the genital sites OR is the manual in error?
The histologies listed in the exception on page 1 are NOT reportable when the topography code is C440-C449. The manual specifically lists the topography codes in 1.b.1. Diagnoses with the listed histologies ARE reportable when the topography code is NOT C440-C449. Genital skin sites are not coded C440-C449 so a note is not needed.
MP/H/Histology--Pituitary: Would you code Crooke cell adenoma as 8272/0 pituitary adenoma?
Yes, code Crooke cell adenoma to 8272/0 pituitary adenoma. According to the WHO classification, it is a variant of adrenocorticotropic hormone (ACTH) producing adenoma (8272/0).
Surgery of Primary Site--Skin: For skin primaries diagnosed 1998-2002, what is the difference between code 40 [Wide excision or re-excision of lesion or minor (local) amputation, NOS] and 50 [Radical excision of a lesion, NOS]?
Codes 40 and 50 are not in the scheme for 2003 forward. See history for coding cases diagnosed 1998-2002.
Primary Site--Unknown & Ill-defined Site: What is the primary site code for multiple malignant rhabdoid tumors (extra renal) in a newborn infant?
Search for additional information on the location of the primary in this case. A tissue specimen (biopsy) is required for a diagnosis of rhabdoid. Additionaly, there should be scans describing any tumors located in sites other than the biopsy site. If the biopsy site is not assumed to be a metastatic site and is the only location of tumor, code the site of the biopsy as the primary site.
If it is not possible to obtain further information for this case, code the primary site C809 [Unknown primary site].
According to our pathologist consultant, extra-renal rhabdoid tumors have been described in organ sites (liver, GI tract, thyroid, CNS, skin, to name a few) as well as in the soft tissue. Many of the organ site tumors are multiple/multifocal, so multiple tumors in one organ do not necessarily imply metastatic disease and therefore unknown primary site.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a diagnosis of bilateral extranodal orbital lymphoma when the same histology is present in both orbits?
This case should be accessioned as a single primary lymphoma of bilateral orbits per Rule M2. Abstract a single primary when there is a single histology. Both orbits showed the same histology. Note 1 for Rule M2 states bilateral involvement of lymph nodes and/or organs is a single primary.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
Reportability: Is "Castleman's Disease" reportable?
For cases diagnosed prior to 1/1/2010:Castleman's Disease is not reportable to SEER. Synonyms for this disease process include: Castleman-Iverson Disease, benign giant lymph node hyperplasia, and angiofollicular mediastinal lymph node hyperplasia. Castleman's Disease is a rare disorder characterized by non-cancerous growths that may develop in the lymph node tissue throughout the body. The plasmacellular form of this disease may progress to lymphoma or plasmacytoma.
For cases diagnosed 2010 forward, 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.
Extension/Ambiguous terminology: How should the terms "entrapped by tumor" and "encased by tumor" be interpreted when coding these fields?
Each case must be reviewed in its entirety to determine the appropriate coding of these fields. However, in general the terms "entrapped" and "encased" should NOT be interpreted as involvement unless there is other clinical or pathologic evidence to support involvement.
Primary site--Melanoma: Should melanoma of the nipple be coded to C50.0 [Nipple] or C44.5 [Skin of the trunk]?
Code to C44.5 [skin of trunk]. External melanoma is an epidermal malignancy, beginning in melanocytes in the basal layer of the epidermis. C50.0 excludes skin of breast.
Primary Site--Hematopoietic, NOS: Are there any guidelines for the use of topography code C420 [blood] rather than C421 [bone marrow], or C424 [Hematopoietic system, NOS] for hematopoietic diseases other than Waldenstrom macroglobulinemia?
For cases diagnosed prior to 1/1/2010:There are no specific guidelines concerning code C420 versus C421 or C424, other than the suggested topography codes in ICD-O-3 (see Rule H). The Hematopoietic task force is in the early phases of developing guidelines for these diseases. This issue will be presented to the task force for their consideration.
For cases diagnosed 2010 forward, 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.
Surgery of Primary Site--Brain and CNS: How is this field to be coded when a patient undergoes stereotactic biopsy of a brain tumor? Path specimen consists of four fragments of tissue measuring .7, .6 and .3 cm.
Assign code 20 [Local excision (biopsy) of lesion or mass. Specimen sent to pathology from surgical event 20].
