Crusted scabies usually occurs in immunocompromised individuals such as those with congenital immunodeficiency disorders (especially cell-mediated immunodeficiency), acquired immunodeficiency syndrome (AIDS)/human immunodeficiency virus (HIV) infection, immunosuppressive treatment (e.g., corticosteroids, calcineurin inhibitors, and cytotoxic drugs), graft-versus-host disease, malignancies (e.g., leukemia and lymphoma), and systemic diseases (diabetes mellitus, systemic lupus erythematosus, dermatomyositis, chronic mucocutaneous candidiasis, and dystrophic epidermolysis bullosa) [6, 8, 10, 11].
