A case of early gastric malignant lymphoma diagnosed and completely resected by strip biopsy.
A case of early gastric malignant lymphoma definitively diagnosed by strip biopsy is reported. The subsequent operation revealed that the strip biopsy had resulted in radical resection. A 55-year-old woman visited our hospital for detailed examination of a small gastric lesion. Histologic findings of the specimens obtained by conventional forceps biopsy indicated reactive lymphoid hyperplasia, although the possibility of malignant lymphoma was not completely ruled out. Strip biopsy was, therefore, performed to establish a definitive diagnosis. Histopathological examinations of the strip biopsy specimen revealed definitive findings of malignant lymphoma, which was B-cell phenotype immunocytochemically. The margin of the resected specimen was free of invasion by malignant lymphoma and no lymph node involvement was suggested by endoscopic ultrasonography, computed tomography, and gallium scintigram. Subtotal gastrectomy was subsequently performed to rule out the possibility of remaining malignant lymphoma cells. It was proven that the strip biopsy removed the lesion completely and no perigastric lymph nodes were involved. While is still controversial as to whether strip biopsy should be adopted for the radical resection of early gastric lymphoma, this procedure can definitely provide excellent specimens for the accurate diagnosis of gastric malignant lymphoma and probably for group III lesions in the stomach.
