A 55-year-old woman with a history of psoriasis, hidradenitis suppurativa, and back pain was referred to our emergency department because of fever and pain around her left eye. She had no respiratory, abdominal, or urinary tract symptoms. Upon physical examination, we noticed erythema around her left eye and swelling of the eyelid. Physical examination of the heart, lungs, and abdomen was unremarkable. On her back, however, we saw a reticular, brown coloured skin lesion (Fig. 1), which was present since a few months.
