Control 18FDG-PET/CT image after interferon alpha administration shows refractory disease (SUVmax 7.4-9.4) (B). Control 18FDG-PET/CT image after 3 months of cobimetinib administration shows disease regression (SUVmax 3.2) (C). Pulmonary tissue sample shows fibrosis with foamy histiocytes and lymphoplasmocytic infiltration (arrow) (hematoxylin eosin x100) (D).
