Inquiry Details

Heme & Lymph Manual & DB
Question:
Primary Site--Heme & Lymphoid Neoplasms: How is the primary site coded for a B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma when a biopsy of the paraspinal muscle and epidural tissue is positive, but there is no indication of lymph node involvement in the chart?
Discussion:
Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to soft tissue of the back, NOS [C496] per Rule PH24 and the Abstractor Notes in the Heme DB for B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.
Code the primary site to the organ when lymphoma is present only in an organ. The lesion is described as epidural (tissue surrounding the dura) and involving paraspinal muscle, NOS. Both are connective or other soft tissues of the trunk, NOS [C496].
B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is a synonym for DLBCL 9680/3. When there is no primary site listed in the Heme DB, go to the Abstractor Notes. In the Abstractor Notes section it states that patients present with lymphadenopathy OR mass lesions in extranodal sites.
SEER*Educate provides training on how to use the Heme Manual and DB.

History:
Code to the soft tissue of back. The lesion is described as epidural (tissue surrounding the dura). Although the muscle was also positive, it is a less likely primary site. B-cell lymphoma intermediate between diffuse B-cell and Burkitt lymphoma is a synonym for DLBCL 9680/3. When there is no information in the primary site box, go to the Abstractor Notes. The abstractor notes state that patients present with lymphadenopathy OR mass lesions in extranodal site(s).
