Discussion:
6/12/12 Excisional biopsy left shoulder soft tissue mass: Suspicious for large B-cell lymphoma.
7/10/12 Excisional biopsy three skin nodules of back: "Composite lymphoma" - primary cutaneous anaplastic large cell lymphoma (CD3 pos, CD4 pos, CD30 pos, ALK neg with partial loss of CD5) and CONCURRENT cutaneous follicular center lymphoma (CD20 pos, PAX5 pos, BCL-6 pos, partially CD10 pos) and flow cytometry revealed results compatible with involvement by a lymphoproliferative disorder of T-cell lineage.
Per imaging performed, there was no involvement of lymph nodes or other organs.
Is the primary site C449 Skin, NOS and histology 9718/3 [Lymphoma, primary cutaneous anaplastic large cell] be correct?
Answer:
Code primary site to C445 [skin, back] and histology to 9718/3 [cutaneous anaplastic large cell lymphoma] .
Per Rule M6, abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location. For this case, there is cutaneous follicular (follicle) center lymphoma (9597/3) and cutaneous anaplastic large cell lymphoma (9718/3).
Per Rule PH22, code the primary site to the site or origin (skin, back) and the histology to the NHL with the numerically highest ICD-O-3 code. In this case, that would be 9718/3.
History:
Code primary site to C445 and histology to 9718/3.
Per Rule M4, abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location. For this case, there is cutaneous follicular (follicle) center lymphoma (9597/3) and cutaneous anaplastic large cell lymphoma (9718/3).
Per Rule PH15, code the primary site to the site or orgin (skin, back) and the histology to the NHL with the numerically highest ICD-O-3 code. In this case, that would be 9718/3.
