[Non-Hodgkin's lymphoma localized at the right ocular medial rectal muscle].

This paper reports a rare case of extranodal non-Hodgkin's lymphoma localized at the ocular muscle, which achieved a long-term remission by combination chemotherapy and irradiation. A 41-year-old man visited the ophthalmology department of Toho University Hospital in December, 1982 because of right conjunctival injection and right exophthalmos which were first manifested in June. The patient was diagnosed as having non-Hodgkin's lymphoma (diffuse medium-sized cell type) by biopsy of the right medial rectal muscle, and was referred to our department on January 17, 1983. A series of examinations revealed that the disease had no invasion into any lymph nodes and other organs. After treatment with two courses of C-MOPP regimen and two courses of ACOP regimen, the patient achieved complete remission and was discharged on July 30. Subsequently he completed two courses of CHOP regimen followed by irradiation (46 Gy). Seven years and three months after the initiation of chemotherapy, the patient has been in a complete remission, requiring no treatment.
