[Late relapse of sarcoidosis. Report of 3 cases].

We report patients who were treated with corticosteroids for sarcoïdosis and developed recurrent disease after 9 and 28 years of remission. The clinical latency, the type III radiographic aspect different from the initial presentation and the spontaneous course with periods of partial or total remission are characteristic of these late relapses. Clinicians should be aware of this uncommon clinical course and monitor cured cases for prolonged periods.
