Question
Multiple primaries--Heme & Lymphoid Neoplasms: Is this two primaries or one? See discussion.

Discussion
Extensive right-sided cervical, supraclav, hilar, mediastinal, gastrohepatic adenopathy. 03/16/2012 bx of cervical nodes shows Diffuse Large B Cell Lymphoma. 04/18/2012 bone marrow shows follicular lymphoma. Treatment started after the bone marrow, pt was given CHOP/Rituxan.

Answer
This is one primary, histology 9680/3.

Rule M12 states that if the original diagnosis is the acute neoplasm (the DLBCL) and a second diagnosis is the chronic (follicular lymphoma) and there is no treatment for the acute neoplasm, it is a single primary. Code the acute neoplasm: the DLBCL.
