We have experienced a case of primary malignant lymphoma of the stomach associated with Sjögren's syndrome.
A 71-year-old male was admitted for surgery in our hospital with the diagnosis of malignant lymphoma of the stomach. Diagnosis of Sjögren's syndrome had been determined two years previously with the main complaints of xerostomia and xerophthalmia.
Total gastrectomy with lymph node excision was performed. The pathological findings were malignant lymphoma (non-Hodgkin's lymphoma of B-cell phenotype, diffuse, median cell type based on L.S.G. classification). Chemotherapy was given for the malignant lymphoma for 5 days. Prognosis was death from acute renal failure in 6 months postoperatively.
