[Scar sarcoidosis: a usually progressive disease (about a case)]. / Sarcoïdose cutanée sur cicatrice: forme habituellement évolutive (à propos d'un cas).

The sarcoidosis is a systemic granulomatous disease. It is usually characterized by skin manifestations which may be suggestive of progressive sarcoidosis with visceral involvement. We here report a case of pulmonary sarcoidosis revealed by the reactivation of an old cutaneous scar following a trauma occurred 20 years earlier. Radiological assessment showed mediastino-pulmonary sarcoidosis stage 2. The diagnosis of sarcoidosis should be suspected in patients with any recent scar modification in order to establish early management.

Generalized annular pustular psoriasis (Milian-Katchoura type) induced by systemic steroids.

The aim of my clinical image is to recall this rare and benign form of pustular psoriasis and to insist on the role of the triggers of pustular psoriasis, mainly the drugs.
