A 55-year-old man presented in January 2002 with a cough, left lower chest wall pain, and fever for 1 month. His medical history was remarkable for a right neck mass in 1998, when an MRI had shown a right submandibular mass with invasion of the surrounding structures (Fig 1
). A wide resection of the mass was performed, with histology showing fibrosis and chronic inflammatory infiltrate (Fig 2
). In 2000, he had presented with right proptosis and right third cranial nerve palsy. His right eye vision was also impaired with a large central scotoma. His eye condition improved with systemic corticosteroid therapy.
