Question:

Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient has a history of chronic myelomonocytic leukemia and a 12/08/2011 subsequent biopsy of the left leg that confirms leukemia cutis? See Discussion.

Discussion:

Patient with a history of chronic myelomonocytic leukemia has been undergoing treatment with Dacogen for three years. On 12/8/11 the patient had a biopsy of the left leg that confirmed a diagnosis of leukemia cutis. How is the leukemia cutis coded?

Answer:

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

Accession a single primary, chronic myelomonocytic leukemia [9945/3], per Rule M2. Accession a single primary when there is a single histology.

This is not a new primary. Leukemia cutis is the infiltration of neoplastic leukocytes into the skin from the existing leukemia. This is an advanced phase of the leukemia and has a poor prognosis.
