BACKGROUND: Rouget du porc, or @entity1707 erysipelas, usually occurs in @entity1 as @entity36579 . @entity1407 forms are more uncommon and can be associated with dermal involvement far from the site of inoculation. We report a case in a @entity1 given corticosteroid therapy for systematic lupus. CASE REPORT: A 50-year-old farmer was seen with @entity221 , infiltrative erythema of the long finger and dorsal lesions on the ring finger which developed after a @entity272 caused by a @entity4186 . The diagnosis of septicemic rouget du porc was made after isolating the germ from blood cultures. There was no associated @entity884 . @entity221 and @entity272 totally regressed after treatment with @entity2756 . DISCUSSION: The diagnosis of erysipeloid was supported by epidemiologic arguments and characteristic clinical features. The corticosteroid therapy was probably a favoring factor for development of @entity295 . Positive diagnosis is usually obtained from blood culture but the germ can be isolated from skin biopsies at the site of inoculation. Our @entity1 was free of @entity884 which should always be suspected. @entity884 is frequent and often fatal. Intravenous high-dose @entity3397 is recommanded treatment.
