[Acitretin-induced pneumonia: an underestimated complication of treatment of psoriasis].
BACKGROUND
Retinoids are known to induce side effects which can be severe. Alveolar and interstitial pneumonia of uncertain pathogenesis can rarely occur when retinoid are used among patients with psoriasis.


METHODS
We report an observation of acute respiratory distress beginning 26 days after introduction of acitretin, a second-generation retinoid. Treatment withdrawal and corticotherapy allow a spectacular amelioration of respiratory conditions.


CONCLUSIONS
Pneumonia induced by retinoid must be known as a side effect of treatment of psoriasis.
