In spite of remarkable progress in the diagnostic techniques of gastric lesions, the diagnosis of gastric lymphoma in its early stage is still not always easy.
Since the present author has experienced the case which was initially diagnosed as reactive lymphoreticular hyperplasia (RLH) on radiology, endoscopy and histology of gastric biopsy in 1972 and was proved to be malignant lymphoma about a year later, the case is reported.
A 34-year-old female with complaints of nausea and vomiting was referred from other hospital where early gastric cancer was suspected on examinations.
Initial examinations in our hospital suggested RLH. Because of no agreement for gastric resection, strict follow-up observation in the out-patient clinic was intended. However, she was hardly seen for a while. When she came in a year later complaining of fever and hunger pain, radiological and endoscopic examinations disclosed a marked progression of the gastric lesion.
Total gastrectomy was carried out under the diagnosis of malignant lymphoma.
A transition of RLH to malignant lymphoma remains to be settled at present; and according to Nakamura's study its frequency is quite rare.
In careful review of biopsy material of this particular case by deeper cuttings, a minute focus suggesting malignant lymphoma was found. This suggests that malignant lymphoma had been already present one year previously.
In this report, X-ray films at initial examination are presented and the diagnosis of gastric lymphoma especially at relatively early stage is discussed.
