Current best practice guidelines for pathologic diagnosis of BIA-ALCL are to produce air-dried smears stained with Wright–Giemsa stain, a cell block for hematoxylin and eosin staining, detection of CD30 by immunohistochemistry and polymerase chain reaction, and T-cell receptor gene rearrangement to detect clonality [7]. Here, TNFRSF8 is linked to anaplastic large cell lymphoma.
