[ Summary ] We described the characteristics of macroscopic and radiographic findings of lymphomatous lesions originating in the stomach, including lymphoma, arising from mucosally associated lymphoid tissues (MALT lymphoma).
Lymphomatous lesions originating in the stomach include classic malignant lymphoma and MALT lymphoma, regarded as a lymphoma of low malignancy. Among malignant lymphomas, the superficial layer type, ALH (atypical lymphoid hyperplasia) and BLH (benign lymphoid hyperplasia) require differential diagnoses apart from histopathological, radiographic and endoscopic diagnoses. Macroscopic and radiographic findings of these lesions were studied. No evident difference was found between the types of lesion, that is, in the appearance rate of findings according to the difference in histological atypia. Findings common to those lesions were numerous round or oval granular shadows, both large and small, sporagic small shadows and irregular reticular shadows. Therefore, these lesions should be regarded and treated as cases similar to gastric lymphoma from the standpoint of clinical diagnosis.
Systematic analyzation of findings is needed, pending catablishment of diagnostic criteria, including histopathological classification when lymphomatous lesions arising from the stomach have increased, in number.
