IntroductionPyoderma gangrenosum (PG) is a neutrophilic dermatosis that is traditionally associated with systemic disorders such as chronic inflammatory bowel diseases, rheumatoid arthritis and malignant hematologic disorders. Its association with systemic lupus erythematosus (SLE) is rare and not well known. We report a case of this association with a review of the literature.Case ReportA 43-year-old female patient, followed for 4 years for SLE, presented a deep ulceration of the anterior face of the left thigh with inflammatory borders, an ulcerated nodule of the right shoulder and four small ulcerations of the back of the right hand. The biopsy of the ulceration of the left thigh concluded to PG. The patient was treated by corticosteroids with complete healing of lesions.ConclusionThe prognosis of lupus does not seem to be aggravated by PG and the treatments of a SLE flare are usually enough for treating associated PG.Copyright © 2019 Société Nationale Française de Médecine Interne (SNFMI).
