A case of ocular reticulum cell sarcoma responded to radiation therapy

We report a case of reticulum cell sarcoma with involvement both in the brain and the eyes. The patient was a 49-year-old man. In 1985, he suffered steroid-resistant uveitis of unknown etiology in his right eye. After that, in 1986, he was aware of a weakness in the right arm and leg and of right sensory disturbances. Histopathological study of a biopsy specimen revealed a malignant lymphoma in the left thalamus, and the lesion was effectively treated by radiation to the brain. In 1987, he complained of visual disturbances in the left eye. According to the history and ocular manifestation, the disease was diagnosed as ocular reticulum cell sarcoma. Radiation therapy to his left orbital cavity was effective and inflammatory signs in the left eye subsided.
