Twenty-seven cases of primary peripheral T-cell lymphomas of the intestine (PTLI) were investigated. Seven patients had histories of malabsorption. The most frequent symptoms at presentation were weight loss,
abdominal pain
, and acute abdomen. The jejunum was the most common site of lymphoma and multifocal disease was found in 72% of the cases. Twenty-two patients (92%) presented with localized disease confined to the intestine and abdominal lymph nodes, only two patients had generalized disease. According to the pattern of lymphoma infiltration and the morphology of the uninvolved small intestinal mucosa, 21 cases were separated histologically into three categories; 1) enteropathy-associated
T-cell lymphoma
(EATCL, n = 9) showing predominant intramucosal lymphoma spread and villous atrophy of uninvolved mucosa with high density of intraepithelial lymphocytes (IEL), 2) EATCL-like lymphoma without enteropathy (EATCL-LLWE, n = 5) but with an infiltration pattern similar to EATCL, and 3)
T-cell lymphoma
without features of EATCL (Non-EATCL, n = 7). Distinctive features of EATCL were the high incidence of malabsorption states, multifocal intestinal disease in all cases, and the high frequency of intestinal recurrences. On frozen sections four of eight PTLI showed the phenotype CD3+ CD4- CD8- HML-1+, which is also expressed on a small subset of normal IEL. The morphologic and immunomorphologic findings suggest that the majority of PTLI is derived from mucosal T lymphocytes. This derivation may be responsible for certain biologic features, such as the preferential spread to and relapse of PTLI at small intestinal sites.

A case of intestinal cytotoxic/suppressor
T-cell lymphoma
with repeated episodes of perforation was seen in a 77-year-old Japanese male who was admitted complaining of severe
abdominal pain
accompanied by high grade fever. Surgery revealed diffuse peritonitis due to perforation in the sigmoid colon. After a loop sigmoid colostomy the patient recovered to some degree. Seven days later, however, another perforation occurred. Several aneurysmal swellings accompanied by perforation in the small intestine, forming a mass of 5 x 5 cm, were seen. Although the patient tolerated this operation, generalized emaciation proceeded and the patient died 10 days late. Histological examination at the second operation showed diffuse medium-sized lymphoma of the Lymphoma Study Group (LSG) classification infiltrating the entire depth of the intestinal wall. Destruction of muscle cells was prominent. An immunohistochemical study using fresh frozen material was positive for CD3, and CD8. This marked destruction of the muscle layer by lymphoma cells may be associated with repeated episodes of perforation.

We describe a case of intestinal
T-cell lymphoma
which was histologically diagnosed of malignant histiocytosis of the intestine. A 47-year-old man was admitted to our hospital because of fever and generalized lymphadenopathy. Mild anemia, leukocytosis, positive CRP and a high level of LDH were noted. Pathological finding of the lymph node was compatible with dermatopathic lymphadenopathy with a slight increase in atypical lymphoid cells. At the 14th day after admission, he suffered from
abdominal pain
and was diagnosed as having perforative peritonitis. In laparotomy, the infiltration of histiocyte-like atypical cells were found around a site of small perforation of the terminal ileum. The findings were compatible with that of malignant histiocytosis of the intestine (MHI). He had recurrent perforations of the small intestine and died of peritonitis and sepsis at the 42nd day. Southern blot analysis of the biopsied lymph node showed TCR-beta gene rearrangement. Some patients diagnosed clinically and pathologically as having MHI may have a
T-cell lymphoma
like our case.

A 40-year-old woman had been diagnosed with Crohns disease in September 1994, but later examinations revealed a primary
T-cell lymphoma
of the colon. Colonoscopic and histological examination showed ulcerative lesions simulating Crohns disease involving the entire colon and the terminal ileum, and she was first diagnosed as having Crohns disease. Differential therapeutic strategies, including corticosteroid, had improved the symptoms which were dominated by
abdominal pain
. When she visited our institute in April 1995, she presented with bloody stool twice a day, 7 kg weight loss in a period of six months and a slightly painful abdomen. Colonoscopic finding showed geographic ulceration on the entire colon, especially rectum and terminal ileum. The histologic examination of specimens from colonoscopic biopsy showed primary peripheral
T-cell lymphoma
of the colon. Any dense lymphocyte infiltrates seen in the biopsy specimens obtained from lesions simulating ulcerative colitis or Crohns disease should be assessed to exclude intestinal lymphoma.

A 63-year-old woman with a 1-year history of
abdominal pain
and intrahepatic cholestasis developed anorexia, weight loss, lassitude and diarrhoea. Studies led to a diagnosis of primary intestinal
T-cell lymphoma
involving especially the proximal small intestine and infiltrating the mesenteric lymph nodes, bone marrow and skin. An associated severe hypoalbuminaemia (1.3 g dL-1) was most probably the result of protein-losing enteropathy. Liver biopsy demonstrated concentric fibrosis of the bile ducts ('onion skin' lesions, with an inflammatory cell infiltrate and lymphoid aggregates) and was considered almost pathognomonic of primary sclerosing cholangitis. Sudden death due to pulmonary embolism occurred and a limited autopsy confirmed the diagnosis. Other associated diseases such as coeliac disease or inflammatory bowel disease were not found. This first report of the simultaneous occurrence of two rare diseases - primary sclerosing cholangitis and intestinal
T-cell lymphoma
- may indicate an intriguing association, possibly mediated by the effect of cytokines released by the infiltrating T-cells into the portal circulation.

A 48-year-old man was admitted to Keio University Hospital in April 1995 with complaints of right
abdominal pain
and weight loss. Hypotonic duodenography showed a mass located in the 3rd portion of the duodenum. Endoscopic biopsy specimens disclosed diffuse large cell non-Hodgkin's lymphoma of the duodenum. The patient was initially treated with 2 courses of CHOP, albeit with no response. A pancreatoduodenectomy and radiotherapy yielded a complete remission. A year later, lymphoma recurred in the right mandible salivary gland, and a second complete remission was obtained after 6 courses of CHOP and radiation. However lymphomas also recurred in the intestine, and lungs, and the patient died of disease progression 38 months after diagnosis. Lymphoma cells were surface CD3 and CD56 positive. An examination of resected intestinal tissues disclosed lymphoma cells morphologically resemble large granular lymphocytes with rearranged TcR genes. These findings indicated the diagnosis of natural killer-like (NK-like)
T-cell lymphoma
. Compared with previously reported cases of NK-like
T-cell lymphoma
, this case was noteworthy for an unusual clinical course characterized by initial appearance in the duodenum, recurrence in a variety of extranodal organs, and the relatively long-term survival of the patient.

We describe a 52-year-old woman who presented with severe diarrhea, nausea, intermittent
abdominal pain
and weight loss of 18 kg within ten months. Jejunal and duodenal ulcers were detected by endoscopy and multiple biopsies revealed villous atrophy of the jejunum. However, neither gliadin nor endomysium antibodies were detected and no clinical and histological improvement was achieved after gluten withdrawal. Despite strong clinical suspicion for intestinal lymphoma many unrevealing biopsies were done. The patient developed intermittent septic fever and diagnostic laparotomy revealed jejunal perforation. Partial jejunal resection was performed and histology confirmed the diagnosis of an intestinal
T-cell lymphoma
without celiac disease. Malabsorption and all intestinal ulcers disappeared during the course of chemotherapy (six cycles CHOP) and the patient recovered remarkably.

A case of primary gastric
T-cell lymphoma
, which was positive for granzyme B, is reported. The patient was a 47-year-old Japanese female who complained of a dull upper
abdominal pain
. Radiographic and endoscopic examinations revealed an ulcerative infiltrative lesion in her stomach. Following the confirmation of a high-grade malignant lymphoma, a distal gastrectomy with regional lymph nodal dissection was performed. The histology of the gastric lesion revealed a malignant lymphoma of the diffuse pleomorphic type without lymph nodal involvement. Immunohistochemistry revealed that the tumor cells were positive for LCA, CD3, TIA-1 and granzyme B, but were negative for CD4, CD8, CD56, CD30, L-26, EMA, TCR alpha/beta and TCR gamma/delta. Because the tumor cells showed T cell nature with cytotoxic activity proved by TIA-1 and granzyme B, and without evidence of further maturation of T cell, a malignant lymphoma originating from extrathymic-derived T cells was suggested.

A 61-year-old male with non-Hodgkin's lymphoma (peripheral
T-cell lymphoma
, unspecified, clinical stage IVb) received autologous peripheral blood stem cell transplantation (PBSCT) during first remission. He was seropositive for cytomegalovirus (CMV) prior to autologous PBSCT. His posttransplant clinical course was complicated by refractory CMV enteritis, which manifested persistent
abdominal pain
, diarrhea, and bloody stool. Generally, gastrointestinal CMV disease is relatively rare after autologous PBSCT. However, our case indicates that CMV infection must be considered as a differential diagnosis in cases of unexplained hemorrhagic enteritis following autologous PBSCT.

Although primary gastric malignant lymphoma accounts for slightly more than 10% of all lymphomas at extranodular sites, it is relatively rare clinically, representing only 1% of all malignant diseases of the stomach. In addition, most such diseases tend to be B-cell lymphoma, while
T-cell lymphoma
is extremely rare. We encountered a patient with primary gastric T-cell malignant lymphoma who, although demonstrating a very rare phenomenon, was negative for antihuman T-lymphotropic virus type 1 antibody. A 73-year-old man was admitted to the hospital with the chief complaint of upper
abdominal pain
. The primary lesion was a type 3 tumor located at the cardia to the posterior wall of the upper body of the stomach, which had invaded the tail of the pancreas and a part of the transverse colon. A total gastrectomy, pancreatosplenectomy, and partial resection of the transverse colon were performed. The surgical section contained a giant ulcerative lesion with its bank cleaved, and a histological examination revealed a diffuse, small cell (Lymphoma Study Group classification) malignant lymphoma. An immunohistochemical analysis of the surgical specimen was positive for LCA/CD45, UCLH-1/CD45RO, and Leu-4/CD3, and negative for L-26/CD20, and it was diagnosed to be primary gastric T-cell malignant lymphoma.
