Question
MP/H Rules/Multiple primaries/Histology: How many primaries are accessioned and how is the histology coded if a patient has a 1.2 cm hepatocellular carcinoma and a 7 cm hepatocellular carcinoma, solid, acinar and trabecular type? See Discussion.

Discussion
FINAL Diagnosis: 2 separate lesions of the liver 1)1.2 cm hepatocellular carcinoma and 2) 7 cm hepatocellular carcinoma, solid, acinar, and trabecular type.

Answer
For cases diagnosed 2007 or later, accession a single primary, hepatocellular carcinoma [8170/3].

The steps used to arrive at this decision are:

Step 1: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text) and go to the Other Sites MP rules because liver does not have site specific rules developed.

Step 2: Start at the MULTIPLE TUMORS module, rule M3. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule M16. There is one tumor with HCC and another tumor with a specific type of HCC.

Hepatocellular carcinomas vary and often display different architectural patterns such as solid, acinar and trabecular.
