For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Abstract the anaplastic T cell lymphoma as a new primary. Code the histology to 9714/3 [Anaplastic large cell lymphoma, ALK-positive].
Rule M15 applies to this cases which instructs you to use the Multiple Primaries Calculator. The result for 9695/3 and 9714/3 is "New Primary."
Apply Rule PH30 to code histology which instructs you to use the Heme DB to determine the histology when rules PH1-PH29 do not apply. In searching the Heme DB for "anaplastic" the first term returned is Anaplastic large cell lymphoma, ALK-positive [9714/3].
