PYODERMA-GANGRENOSUM AND STERILE MULTIFOCAL OSTEOMYELITIS PRECEDING THE APPEARANCE OF TAKAYASU ARTERITIS

A 9-month-old infant had pyoderma gangrenosum (PG) and sterile osteomy elitis. Three years later the patient developed Takayasu arteritis (TA ). Sterile osteomyelitis was reported in approximately 30 patients wit h different skin lesions, but never together with pyoderma gangrenosum . The association of PG and TA has been reported rarely, and then main ly in adults or in children over age 9 years. This rare association sh ould alert physicians with a case of infantile PG of unknown etiology to consider the possible diagnosis of TA.
