A 54-year-old woman with well-controlled chronic plaque psoriasis presented with a 2-day history of painful rash and fever. Widespread erythematous patches with overlying, coalescing pustules were seen on examination.

A 77-year-old man presented to our dermatology clinic with several erythematous, purpuric, scaling plaques over his genital and suprapubic regions, which had appeared over the previous year (Figure 1A). Similar lesions had developed in both axilla (Figure 1B) over the previous 6 months. He had no history of cancer. Initially, the lesions were assumed to be eczema and then fungal infections, treated with topical steroids and antifungal agents, respectively, without improvement.
