Clinical Presentation

A 28-year-old man presents from jail with chronic cellulitis of the leg with an ulcer.

History and Physical Examination

History. The patient has a 3-month history of a nonhealing ulcer on his leg. It started as a red bump that evolved into a chronic ulcer. The ulcer is currently the size of a quarter and has grown from dime size. It is moderately painful. While in jail, he was given a course of cephalexin and ciprofloxacin with no change in the ulcer. He denies any fever, chills, or rigor and has been gaining weight on a typical incarceration diet. The rest of the review of systems is negative.
