Lymphomatoid papulosis (LyP) with DUSP22 rearrangement is an uncommon subtype of lymphomatoid papulosis featured histologically by two distinct patterns of epidermotropic cells, weakly CD30+ small- to medium-sized T-cells and a dermal infiltrate of strongly CD30+ medium- to large-sized T-cells. DUSP22 rearrangement is detected more frequently in anaplastic large cell lymphoma (ALCL) than in LyP. Here, TNFRSF8 is linked to anaplastic large cell lymphoma.
