Introduction:
Sarcoidosis is an unexplained systemic granulomatosis. Bone localizations of the disease are rare. We report a maxillary localization.
Case:
A 35-year-old patient consulted for facial dysmorphia first observed 2 years before. This swelling was associated to nodular panniculitis lesions and xerostomia. The facial asymmetry was due to maxillary gingival and alveolar swelling. It was associated with scarring in the legs and a purple nodular facial lesion. Lip and jaw biopsies revealed epithelioid and giant cell granulomas without caseous necrosis. The panoramic dental X-ray showed diffuse horizontal alveolar ridge lysis and CT scan revealed an osteolytic lesion of the right maxilla associated to a bone-condensing lesion of the left hemi-mandible.
Discussion:
The diagnosis of sarcoidosis is made in case of epithelioid and giant cell granulomas without caseous necrosis and the ruling out of other possible diagnoses, including tuberculosis. Bone involvement is rare; face and maxillary localization are extremely rare. The recommended treatment is corticosteroids. Facial remodeling surgery is not recommended.

01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
