title: [Rapid bone marrow dissemination of gastrointestinal lymphomas after surgical resection].
abstract: We describe two cases of gastrointestinal lymphoma associated with rapid bone marrow dissemination after surgical resection. Case 1: A 73-year-old male was diagnosed as having malignant lymphoma originating from ileocaecal region (diffuse medium-sized, B cell type). Tumor (8 x 8 cm) was resected but infiltrated to the peritoneum and curative operation could not be done. Two weeks after operation, elevation of LDH, pancytopenia and bone marrow infiltration of lymphoma cells developed and he died of respiratory failure. Case 2: A 69-year-old female was diagnosed as having remnant gastric lymphoma (diffuse large, B cell type). Tumor size was 5 x 4 cm and swelling of the third lymph nodes was found, so curative operation could not be done. Two months after operation bone marrow infiltration of lymphoma cells was observed and she is now undergoing chemotherapy. Surgical resection is performed in the majority of patients with localized gastrointestinal lymphoma. But the operation of the advanced case must be carefully done, because the operative procedure may sometimes facilitate growth and metastasis of tumor.
