Amyloid tumor of the orbit.

abstract：:We investigated nine patients with rhabdomyosarcoma in the head and neck (6-53 years of age), using CT and MRI. The tumours originated in the paranasal sinuses (3), cheek (2), soft palate (1), orbit (1), sternocostoclavicular muscle (1) and parapharyngeal space (1). The histological subtype was embryonal in five, alve...
