Abstract:
A 33-year-old Caucasian woman presented 6 months postpartum with acute sarcoid arthritis with interstitial lung disease and minimal hilar adenopathy. Nine years before, she had experienced transient ankle arthritis and erythema nodosum. Her chest radiograph at that time was normal, and her symptoms were attributed then to initiation of the birth control pill. It appears that this patient had an incomplete Lofgren's syndrome, which might have initially occurred nearly a decade before a diagnosis of pulmonary sarcoidosis was made. Her sarcoidosis has improved, and she appears to have a good prognosis, which is typical of Lofgren's syndrome.
