Question:

Multiple Primaries (Pre-2007)--Skin: If a patient presents with two separate lesions on the left cheek (i.e., left lateral cheek and left upper cheek) that both are histologically confirmed to be superficial spreading melanoma on the same day, is this coded as one or two primaries?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Code as one primary.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
