Angioimmunoblastic T-cell lymphoma (AILT) is a peripheral T-cell lymphoma often complicated autoimmune phenomena such as autoimmune cytopenia, and is a truly rare type of NHL. In order to investigate the clinical features, pathological manifestation of this lymphoma, and to explore its therapy protocol, a 37-years old patient with AILT was investigated. The routine blood examination, bone marrow smear, lymphonodus biopsy, Coombs test, flow cytometry for bone marrow mononuclear cells, serological test, immunochemistry method etc were performed for this patient. The results showed that the systemic lymphadenectasis and hepatosplenomegaly were seen in patient, the cervical lymphonode biopsy revealed AITL. The hematoglobin level and number of reticulocytes were very low. Coombs test was positive. Simultaneously, the bone marrow aspirate revealed erythroid aplasia. The warm type autoimmune hemolytic anemia (AIHA) and pure red cell aplasia (PRCA) were co-existed. After one course of chemotherapy with CHOP-E, infiltration sign of AITL patient with AIHA and PRCA disappeared. In conclusion, the AITL patient complicated with AIHA and PRCA was successfully diagnosed, the lymphonode biopsy and bone marrow smear showed more significant, the chemotherapy protocol of CHOP-E can give some effect to cure such angioimmunoblastic T cell lymphoma.

One case of arthritis complicating leukemia is described in which leukemic cells were identified in synovial fluid by light microscopy. Although arthritis is a well-known manifestation of leukemia with an incidence of 13.5%, the pathogenesis often is unclear, and the direct demonstration of leukemic cells in synovial fluid has been very uncommon. A 16 year-old male patient was admitted due to left elbow joint pain and swelling. Synovial fluid examination revealed blast cells and this finding has directed to a final diagnosis of acute lymphoblastic leukemia.

PURPOSE: To present a case of peripheral T-cell lymphoma presenting as painful ophthalmoplegia. METHODS: A 61-year-old woman presented with a 2-week history of headache and eyeball pain. Examination showed mild exophthalmos, complete ophthalmoplegia, and ptosis of the left eye. Under the impression of nonspecific orbital inflammation, she was treated with oral prednisone with initial response. Two months later, she revisited the clinic with exacerbated symptoms. Anterior orbitotomy and incisional biopsy was performed for the inferior rectus muscle lesion. RESULTS: Histopathologic examination revealed an infiltrate of atypical lymphoid cells between degenerative muscle bundles. It was consistent with peripheral T-cell lymphoma. A metastatic workup was performed without any evidence of extraorbital tumor. The patient was recommended to be treated with chemotherapy, however, refused to take the treatment. The patient died of progression of the disease in a month. CONCLUSIONS: T-cell lymphoma in the orbit can present as painful ophthalmoplegia and take a rapid clinical course. The disease should be regarded as one of the differential diagnosis for painful ophthalmoplegia refractory to corticosteroid therapy.

Primary non-Hodgkin's lymphoma of bone (PLB) is rare, and generally presents as a single extensive and destructive bone lesion. Histopathologically, most cases present as diffuse large B-cell lymphoma, and T-cell lymphoma is rare. By contrast, multiple myeloma is a disease defined as the neoplastic proliferation of a single clone of plasma cells producing a monoclonal immunoglobulin. We report a case of multiple myeloma that developed during treatment of PLB in a type of T-cell. A 48-yr-old man was diagnosed as T-cell PLB, stage IE, 18 months ago. The patient received the chemoradiotherapy and salvage chemotherapy for PLB. However, the lymphoma progressed with generalized bone pain, and laboratory findings showed bicytopenia and acute renal failure. On bone marrow biopsy, the patient was diagnosed as having multiple myeloma newly developed with primary T-cell lymphoma of bone. In spite of chemotherapy, the patient died of renal failure.

Enteropathy-associated T-cell lymphoma (EATL) is an unusual primary gastrointestinal lymphoma, particularly associated with celiac sprue. This tumor usually affects the jejunum and grossly presents as multiple circumferential ulcers without the formation of definite tumor masses. Moreover, mesenteric lymph nodes are commonly involved. The patients have typically suffered from abdominal pain, diarrhea, or weight loss whereas some patients may manifest with nonspecific symptoms for a period of years or an acute emergency of perforation, obstruction, or hemorrhage. The clinical course of EATL is very unfavorable and the prognosis is poor. Both celiac sprue and EATL are very rare diseases in Asia, except India and Middle East. We report a 60-year-old male diagnosed as having EATL after segmental small bowel resection, who presented with recurrent gastrointestinal bleeding.

Natural killer (NK)/T-cell lymphomas represent a rare type of lymphoma derived from either activated NK cells or cytotoxic T cells. They are most commonly extranodal and tend to present as destructive lesions within the midline facial structures. Other than the nasal cavity and Para nasal sinuses, several other extra nodal sites of involvement have been reported, including the pharynx, gastrointestinal tract, and testis. Occasionally, pleural effusion has also been observed. Here, a case of lymphoma of NK/T-cell type presented as pleural effusion was reported. The patient was previously misdiagnosed as B cell non-Hodgkin's lymphoma by pathological and immunohistochemistry (IH) analysis for pleural membrane biopsy specimen. After the analysis of the pleural fluid cells by a combination of morphologic, immunophenotypic, cytogenetic and molecular (MICM) methods in Beijing Dao-Pei hospital, some lymphoblasts were found morphologically, which expressed cytoplasmic CD3 (cCD3) and CD56 by flow cytometry analysis and had a clonal T-cell receptor gamma (TCR-gamma) gene rearrangement by molecular analysis, so that the diagnosis was finally corrected as NK/T-cell lymphoma and an allogeneic stem cell transplantation was successfully performed. In conclusion, this unusual case highlights the significance of MICM combined techniques for the diagnosis of lymphoma, as well as an unusual presentation of a rare disease and the successful treatment.

Extranodal NK/T cell lymphoma is a relatively uncommon type of non-Hodgkin's lymphoma, which is prevalently distributed in Asia and South America, and is highly associated with Epstein-Barr virus (EBV) infection. Due to its highly aggressive course and poor response to treatment because of its multi-drug resistance, for the timebeing there is not yet a definite treatment strategy. The clinical manifestation, pathological diagnosis and the progress of treatment methods of ENTNKCL are reviewed below.

Enteropathy-type T-cell lymphoma (ETTL) is a rare disease with a poor prognosis. According to the World Health Organization (WHO) classification, it is a subtype of the peripheral T-cell lymphomas. This disease is associated with gluten-sensitive enteropathy, has a high risk of intestinal perforation and obstruction, and is refractory to chemotherapeutic treatment. We report the case of a 73-year-old woman who was diagnosed with enteropathy-type T-cell lymphoma of the small intestine, which was positive for the markers of cytotoxic T cells, CD3, CD8, and CD56, on immunohistochemical staining after resection of the perforated terminal ileum.
