[Sarcoidosis in a cicatrix: apropos of 5 cases].
The authors report 5 cases of sarcoidosis developed on scars. Sarcoidosis may be isolated (1 case); it may precede (1 case) or accompany systemic sarcoidosis, or occur during a relapse (3 cases). Dermatologists who observe cicatricial changes always suspect sarcoidosis. It is therefore important that physicians should examine the scars of their patients with suspected sarcoidosis, since biopsy of these scars is easily performed, confirms the diagnosis and avoids more invasive explorations.
