Abstractor Notes
(This code is effective for cases diagnosed 2021 and later. For cases diagnosed prior to 2021 see code: 9702/3.)
ALK- ALCL involved both lymph nodes and extranodal tissue (e.g., the bone, soft tissue, and skin), although extranodal sites are less commonly involved than in ALK+ ALCL.
Most patients present with advanced stage (III-IV) disease, with peripheral and/or abdominal lymphadenopathy and B symptoms.
For breast implant-associated anaplastic large cell lymphomas, the tumor cells may be localized to the seroma cavity or may involve the pericapsular fibrous tissue, sometimes forming a mass. Locoregional lymph nodes may be involved. For this diagnosis, primary site is the breast (C50_)

Diagnostic Confirmation
This histology can be determined by positive histology (including peripheral blood) with or without genetics and/or immunophenotyping. Review the Definitive Diagnostic Methods, Immunophenotyping and Genetics Data sections below, and the instructions in the Hematopoietic Manual for further guidance on assigning Diagnostic confirmation.

Definition
Anaplastic large cell lymphoma, ALK-negative (ALK-) is defined as a CD30+ T-cell neoplasm that is not reproducibly distinguishable on morphological grounds from ALK-positive (ALK+) ALCL, but lacks ALK protein expression.
ALK-ALCL must be distinguished from primary cutaneous ALCL (C-ALCL), other subtypes of CD30+ T-cell or B-cell lymphoma with anaplastic features, and classic Hodgkin lymphoma (CHL).
Breast implant-associated anaplastic large cell lymphoma is a provisional entity that is a T-cell lymphoma with morphological and immunophenotypic features indistinguishable from those of ALK-negative anaplastic large cell lymphoma (ALCL), arising primarily in association with a breast implant.
