Abstract;A 64-year-old woman presented with swelling of upper eyelid and proptosis in her left eye since 2 months before. Magnetic resonance imaging(MRI) showed swollen superior rectus muscle leading to the diagnosis of orbital myositis. Clinical remission was obtained following systemic prednisolone. She developed severe ocular pain, headache and diplopia in her left eye 18 months later. A tumorous lesion was detected in the left orbit extending from the superior rectus muscle by MRI. The lesion was diagnosed as malignant lymphoma by immunohistochemistry and rearrangement analysis of immunoglobulin of biopsied specimen. This case illustrates that malignant lymphoma may develop from orbital myositis. (author abst.)
