Question:

Histology--Heme & Lymphoid Neoplasms: How is the histology coded if a biopsy final diagnosis is diffuse large B-cell lymphoma but the physician's final diagnosis favored anaplastic large cell lymphoma? See Discussion.

Discussion:

Patient has diffuse intrathoracic, intraabdominal and pelvic lymphadenopathy. An inguinal lymph node biopsy showed diffuse large B-cell lymphoma. The physician's final diagnosis favored anaplastic large cell lymphoma, but wanted to confirm this with FISH. The patient clinically deteriorated so the FISH studies were not done. Which histology is coded?

Answer:

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

The histology should be coded as diffuse large B-cell lymphoma [9680/3]. The biopsy pathology report definitively diagnosed DLBCL. The physician's diagnosis cannot be used because it is an ambiguous diagnosis only, "favored anaplastic large cell lymphoma." "Favor" is an ambiguous term.
