1/716. Poor outcome of autologous stem cell transplantation for adult T cell leukemia/lymphoma: a case report and review of the literature.A limited number of patients with adult T cell leukemia/lymphoma (ATL) who received autologous stem cell transplantation (ASCT) have been reported. We report here a case of fatal systemic candida krusei infection in a female patient with ATL undergoing ASCT. All of the eight patients (including seven patients in the literature) with ATL who received ASCT developed relapse of ATL or death due to ASCT complication, irrespective of subtype or remission state of ATL, source or selection of SCT or conditioning regimen. At present, ASCT appears to provide little benefit for ATL in contrast to that for other types of aggressive non-Hodgkin's lymphoma.- - - - - - - - - - ranking = 1keywords = lymphoma, leukemia, l (Clic here for more details about this article) |
2/716. Two cases of toxoplasmic encephalitis in patients with acute T-cell leukaemia and lymphoma.Two cases of opportunistic cerebral infections in hiv-negative cancer patients due to chemotherapy induced immunosuppression are reported. A 61-year-old patient with low grade lymphoma (immunocytoma as referred to the Kiel classification) developed stereotactical biopsy proven toxoplasmic encephalitis 6 months after initiation of fludarabine treatment. The lymphoma had been diagnosed 8 years earlier and had been treated with several different regimens. In the second case, a 55-year-old patient developed neurological symptoms while in complete remission from acute T-cell leukaemia. The patient had been treated with a multidrug chemotherapy regimen including radiotherapy of the brain and intrathecal chemotherapy. When toxoplasmic encephalitis was bioptically diagnosed the patient was on maintenance chemotherapy with methotrexate and mercaptopurine for 12 months. The patients' characteristics and outcome are reported and the potential pathogenesis is discussed.- - - - - - - - - - ranking = 0.9996011361588keywords = lymphoma, l (Clic here for more details about this article) |
3/716. Intrasellar malignant lymphoma developing within pituitary adenoma.A mixed lymphoblastic T cell lymphoma and gonadotroph cell pituitary adenoma occurred 25 years after first resection of the adenoma. Within 1 year the lymphoma overgrew the adenoma, but was still restricted to the sellar region. Histologically, lymphoma and adenoma components were tightly admixed. Possible pathogenetic pathways for intra-adenomatous lymphoma development include monoclonal expansion of T cell infiltrates, expression of adhesion molecules specific for adenoma endothelium, and production of mitogenic pituitary hormones.- - - - - - - - - - ranking = 1.3327993840725keywords = lymphoma, l (Clic here for more details about this article) |
4/716. Primary T-cell lymphoma of the thyroid.BACKGROUND: The routine use of immunocytochemical analysis has led to the recognition that many thyroid neoplasms previously diagnosed as anaplastic or small cell carcinomas are actually lymphomas of the thyroid. The great majority are B-cell lymphomas which can be associated with Hashimoto's thyroiditis. In spite of this, thyroid lymphomas are still not commonly recognized as a significant part of thyroid differential diagnosis. methods: A rare case of a primary T-cell lymphoma of the thyroid gland is presented along with general clinical history and physical findings which should make the practitioner suspicious of a thyroid lymphoma. The usefulness of radiology scans and fine-needle aspiration are discussed. RESULTS: Both prognosis and treatment options are very different for thyroid lymphomas and anaplastic carcinoma. CONCLUSIONS: cyclophosphamide/adriamycin/vincristine/prednisolone chemotherapy/radiotherapy regimens have proven to be very effective for most thyroid lymphomas.- - - - - - - - - - ranking = 1.8325978067514keywords = lymphoma, l (Clic here for more details about this article) |
5/716. Auditory brainstem response and neuropathology in a case of systemic T-cell lymphoma with intracranial metastasis.A 58-year-old male with systemic T-cell lymphoma involving the brainstem eccentrically, showed varying abnormal auditory brainstem responses (ABRs). The initial ABR demonstrated a prolonged V wave peak latency and an I-V IPL on admission. Four months later, all waves were absent bilaterally. Neuropathological examination at autopsy revealed that most of the nuclei and tracts associated with the auditory system were destroyed by lymphoid cell infiltration. It suggested that in the early stages of this disease, lymphoid cells could have involved the lower brainstem and, subsequently, in the advanced stages invaded the inferior colliculus.- - - - - - - - - - ranking = 0.83300192463459keywords = lymphoma, l (Clic here for more details about this article) |
6/716. Primary pulmonary collision tumor including squamous cell carcinoma and T-cell lymphoma.We report a very rare occurrence of a primary collision tumor in the lung consisting of squamous cell carcinoma and T-cell lymphoma. A squamous cell carcinoma was diagnosed histologically following a transbronchial lung biopsy in a 71-year-old woman, but the other component was diagnosed histologically and immunohistochemically only on examination of the resection specimen. The malignant lymphoma was stained by the monoclonal antibody UCHL-1 (anti-D45RO) against t-lymphocytes but was not stained by the L26 (anti-CD20) antibody against b-lymphocytes. Immunostaining for CD3 was positive, confirming a T-cell lineage. Despite systemic chemotherapy, the patient died 7 months after operation, from progression of the lymphoma. Our case, which illustrates interesting attributes of collision tumors, consisted of an ordinary squamous cell carcinoma and a rare T-cell lymphoma arising in the lung, with the latter part of the combination dictating subsequent treatment and outcome.- - - - - - - - - - ranking = 1.3328021862282keywords = lymphoma, l (Clic here for more details about this article) |
7/716. Primary esophageal T cell lymphoma.A 60 year-old woman with primary esophageal T-cell lymphoma in clinical stage I(E)B is presented. Immunohistologic examination showed tumor cells to be positive for anti-LCA, anti-UCHL-1, anti-MT-1, anti-CD3 antibodies, and negative for anti-L26 antibody. Disappearance of dysphagia and improvement in esophageal findings were noted after 65 Gy of irradiation, and biopsy specimens from the esophagus revealed no malignancy. Primary esophageal lymphoma is extremely rare, and this T-cell lymphoma is only the fourth case reported in the literature.- - - - - - - - - - ranking = 1.1661989466051keywords = lymphoma, l (Clic here for more details about this article) |
8/716. Myositis and malignancy: is there a true association?There may be an association between polymyositis/dermatomyositis and malignant disease. Cancer occurs in patients with polymyositis/dermatomyositis with a frequency estimated between 2.5% and 29% (relative risk 1.0 to 6.5). We present two such cases, associated with colorectal carcinoma and non-Hodgkin's lymphoma respectively, together with an overview of existing controlled studies in the area.- - - - - - - - - - ranking = 0.16660061260207keywords = lymphoma, l (Clic here for more details about this article) |
9/716. Natural killer cell lymphoma of the small intestine: diagnosis by flow cytometric immunophenotyping of paracentesis fluid.Natural killer (NK) cell lymphoma is a mass-forming neoplasm of putative NK cell lineage that typically appears in extranodal locations and has the following immunophenotype: CD2 positive, surface CD3 negative, cytoplasmic CD3 positive, and CD56 positive. We report a case of small-intestinal NK cell lymphoma that was originally diagnosed as an enteropathy-associated t-cell lymphoma based on paraffin immunohistochemistry. However, subsequent flow cytometric immunophenotyping of paracentesis fluid resulted in the correct diagnosis. We describe the case to illustrate the usefulness of this technique, which has not previously been described in such a case.- - - - - - - - - - ranking = 1.1662022741651keywords = lymphoma, l (Clic here for more details about this article) |
10/716. Primary T-cell lymphoma of the duodenum: report of a case.A case of primary non-Hodgkin's T-cell lymphoma of the duodenum is presented. A 41-year-old man was hospitalized in 1984 complaining of abdominal distention and vomiting. Hypotonic duodenography showed an encircling filling defect in the second portion of the duodenum, and a biopsy specimen revealed features of malignancy suggestive of either undifferentiated carcinoma or malignant lymphoma. Radical surgery (pancreaticoduodenectomy) was performed, after which chemotherapy was administered. A histological evaluation of the duodenal tumor showed it to be non-Hodgkin's lymphoma. It was a diffuse, large-cell type, which immunohistochemically suggested it to be of T-cell origin. Currently the patient is doing well, with no evidence of disease recurrence 13 years after surgery.- - - - - - - - - - ranking = 1.166199384442keywords = lymphoma, l (Clic here for more details about this article) |
