A 69-year-old woman was admitted to hospital due to abdominal pain. An enlarged spleen was detected and extirpated. Histological examination and FACS analysis could not clearly differentiate between a splenic marginal zone lymphoma and a mantle cell lymphoma. Using molecular cytogenetic techniques, a complex karyotype including a translocation between chromosome 11 and 14 consistent with a triple fusion between heavy chain immunoglobulin locus (IgH) and cyclin D1 (CCND1) was demonstrated. Overexpression of cyclin D1 was detected by immunostaining. Thus the diagnosis of a splenic blastoid mantle cell lymphoma could be established. In this report, various aspects of differential diagnosis of splenic lymphomas are discussed.

We performed a clinical analysis on 8 patients with primary follicular lymphoma in the duodenum taken from among 26 cases of primary gastrointestinal malignant lymphoma treated in our division. The median age was 60 years (range 48 to 82 yr). The ratio of males to females was 4:4. The chief complaints were no symptoms in 4 cases, heartburn in 2 cases, lower abdominal pain in 1 case, and back pain in 1 case. All patients were in clinical stage I EA. Gastroendoscopic findings showed multiple whitish granules around the ampulla of Vater in all patients. Involvement of the site in 6 cases was only located at the second portion; lesions in the other 2 cases were located at the second portion, and at the third portion or fourth portion, respectively. A histological study showed follicular lymphoma grade 1, and an immunohistological study demonstrated that the lymphoma cells were positive for CD79a, CD10, CD20, and bcl-2. Five patients were positive for the FISH analysis fusion signal of IgH/bcl-2 genes. Rituximab with CHOP therapy was performed for 7 patients. Seven patients are currently alive, and one died of uterine cancer. At the medium-term 39 month-follow-up, 7 patients were in complete remission, and 1 patient was in partial remission. Rituximab with CHOP (CVP) therapy is a possible treatment for primary follicular lymphoma in the duodenum. Further consideration of appropriate therapy for this disease might be necessary.

We report the case of an eight-yr-old child with early onset PTLD half a year after renal transplantation. The patient developed gastrointestinal pain and bowel biopsies revealed imposing lymphoid infiltrates with small spots of lymphoid blasts in the colonic mucosa. These findings were interpreted as transplantation associated B-cell stimulation. However, the persistent severe abdominal pain led to the resection of a jejunal segment. Here, gut wall perforation caused by a tumor mass was seen. Histologically, a blastic lymphoid cell proliferation of B-cell origin with high proliferation rate and EBV association could be demonstrated. IgH rearrangement analysis and in situ hybridization revealed an oligoclonal B-cell pattern. Reduction of immunosuppression and treatment with rituximab led to lymphoma remission and conversion of EBV serology four wk later. The report presented herein demonstrates the evolution of an oligoclonal lymphoproliferation with direct disease progression towards EBV associated PTLD by analyzing different stages of the disease.
