Question:

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?

Discussion:

Answer:

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

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.
