Crusted (Norwegian) scabies as a strong marker of adult T‐cell leukemia/lymphoma in HTLV‐1 infection

Abstract

Key Clinical Message We present a rare case of crusted scabies in an human T‐cell lymphotropic virus type 1 (HTLV‐1) infected woman prior to onset of adult T‐cell leukemia/lymphoma (ATL). We highlight the importance of this rare form of scabies as a prediagnostic sign of ATL, requiring high suspicion and monitoring of possible symptoms for early detection of ATL.
