An adult presented with a 1-year history of worsening, painful lesions on the fingers of the right hand. The patient first noticed 1 lesion at the fingertip of the right third digit about 2 weeks after an injury to the hand. The lesion subsequently worsened and spread up this digit and affected the second digit as well. Treatment with multiple courses of antibiotics over the next few months for presumed cellulitis was followed by mild improvement but subsequent worsening after stopping antibiotic treatment. A diagnosis of psoriasis was made, based on a biopsy of a lesion on the patient’s trunk, and treatment was begun with topical corticosteroids without any improvement after 2 months. There was no relevant medical or family history.
