The case of a patient with gastric malignant lymphoma associated with systemic sarcoidosis is reported. The patient's sarcoidosis was identified by the findings of bilateral hilar lymphadenopathy and secondary glaucoma. Biopsy of a cervical lymph node showed epithelioid cell granuloma; the sarcoidosis was diagnosed 15 years previously. She had been treated with prednisolone for 5 years until 1979. Proximal gastrectomy, splenectomy, and lymph node dissection were done in 1989. The tumor was diagnosed as malignant lymphoma of the diffuse large cell type according to the Working Formulation. There was no infiltration of lymphoma cell in the 45 dissected lymph nodes, but sarcoid nodules were observed in all nodes. Only three cases of gastric malignant lymphoma complicating sarcoidosis have been reported to the authors' knowledge. Further study should be done in support of the concept of a sarcoidosis-lymphoma syndrome.
