  • Figure 1
    Mandible X-ray
     

    Oblique view. A scalloped lytic lesion in the anterior region of the body of the mandible.

     
    Area of Interest: Head and neck; Imaging Technique: Plain radiographic studies;

    AP view. The lytic lesion is in the right side of the body of the mandible.

     
    Area of Interest: Head and neck; Imaging Technique: Plain radiographic studies;
     
     
  • Figure 2
    Ultrasound

    Heterogeneous soft-tissue lesion, with some calcifications and well defined lobulated contour.

     
    Area of Interest: Head and neck; Imaging Technique: Ultrasound;
     
     
  • Figure 3
    CE-CT (soft-tissue window)
     

    Axial view of the soft tissue mass. It is a rather homogeneously enhancing mass with well defined limits, growing outside the bone.

     
    Area of Interest: Head and neck; Imaging Technique: CT;

    Axial image 20 mm above Fig 4a where the mass reaches its maximum length. Notice the way it displaces the tongue but does not invade any of the nearby structures suggesting a benign behaviour.

     
    Area of Interest: Head and neck; Imaging Technique: CT;
     
     
  • Figure 4
    CT (bone window)
     

    Lytic expansive lesion in the mandible. Some irregularity and disruption of the cortex can be seen.

     
    Area of Interest: Head and neck; Imaging Technique: CT;

    Lytic lesion in the right side of the maxilla, without perceptible cortical rupture.

     
    Area of Interest: Head and neck; Imaging Technique: CT;

    Histologic samples
     

    Numerous osteoclastic multinucleated giant cells are present in sheets of stromal, ovoid to spindle, stromal cells. There is no nuclear atypia.
