Adult-onset Still’s disease is a rare condition that typically presents itself with intermittent fever, arthralgia and salmon colored rash. The involvement of the in lung is less common and very rare. Diagnosis is relatively difficult because of the presence of non-specific symptoms and the lack of serological markers specific to the disease. We report the case of a patient having a pulmonary infiltrate/infiltration compatible with pneumonia, cutaneous/skin rash and persistence of fever with multiple admissions to the Emergency Room due to the failure of treatment with antibiotics. After an appropriate work-up, a diagnosis of adult-onset Still’s disease was made.
