Question:

Histology/Reportability--Heme & Lymphoid Neoplasms: Is a diagnosis of follicular lymphoma in situ of the gallbladder reportable for 2010? See Discussion.

Discussion:

Coding the histology to 9690 [Follicular lymphoma] with a behavior of 2 [in situ] causes many edits including SEER and CS edits to fail. According to the chief of pathology, this is a recently identified pathologic entity.

Answer:

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Currently, lymphoma in situ is not reportable. It is true that this is a recently identified pathologic entity. Our experts say that there is still some controversy to be ironed out regarding the criteria for identifying an in situ lymphoma. Their recommendation was to wait until clear guidelines had been established for the pathologists before we start collection of in situ lymphomas. We anticipate collecting these entities in the future.
