Abstract
Psoriasis is a chronic inflammatory disease that affects the skin variably, according to genetic and environmental factors. Some patients may benefit from systemic treatment with immunobiological agents, drugs that can be accompanied by several adverse effects. A case of a 58-year-old patient undergoing treatment for psoriasis with adalimumab for five years is reported. Alterations compatible with interstitial pneumonia were detected with important regression after adalimumab discontinuation. This case is relevant due to the scarcity of reports on late pulmonary adverse effect of anti-TNF treatment of psoriasis.
