ALK+ ALCL in the setting of adalimumab-related hidradenitis suppurativa

Clin Case Rep. 2023 Apr 12;11(4):e7156. doi: 10.1002/ccr3.7156. eCollection 2023 Apr.

Abstract

This ALK-positive anaplastic large cell lymphoma (ALCL) case highlights the importance of considering ALCL in the setting of iatrogenic immunosuppression in hidradenitis suppurativa patients. Diagnosis of ALCL can be challenging in situations with very low viability/cellularity, negative CD3 and/or other T-cell markers, and immunosuppression.

Keywords: ALCL; ALK; KRAS; adalimumab; iatrogenic immunodeficiency‐associated.
