Computed tomography (CT) of the chest visualized a tumor of soft-tissue density that expanded from the right pleural cavity into the subcutaneous tissue (Fig. 1A). Fluorine-18 2-fluoro-2-deoxy-d-glucose (18F-FDG) positron emission tomography (PET)-CT revealed an accumulation of 18F-FDG in the mass and along the pleura (Fig. 1B).
Microscopy of the tissue specimen revealed a FBG accompanied by foreign-body giant cells, histiocytes, and inflammatory cells (x10).
