Neck Lymph Node (neck + lymph_node)
Selected AbstractsSclerosing encapsulating peritonitis (abdominal cocoon) associated with liver cirrhosis and diffuse large B-cell lymphoma: Autopsy casePATHOLOGY INTERNATIONAL, Issue 9 2009Sohsuke Yamada A case of sclerosing encapsulating peritonitis (SEP) associated with liver cirrhosis (LC) and complicated by diffuse large B-cell lymphoma (DLBCL) is reported herein. A 49-year-old Japanese man had undergone peritoneo-venous shunt against refractory ascites due to hepatitis C virus-positive uncompensated LC for 2 years. After he received a diagnosis of DLBCL of the left neck lymph node 3 months before his death, palliative care was given because of his poor general condition. He developed severe abdominal distention and pain over 1 week and was found to have marked ascites and whole bowel lumped together on abdominal CT. At autopsy, the peritoneum was covered with a thick white membrane and the bowel could not be distinguished, which was macroscopically characterized by a cocoon-like appearance. Histology indicated a proliferation of diffusely thickened or hyalinized fibrocollagenous tissue in the entire peritoneum with a slight chronic inflammatory infiltrate and without remarkable change of mucosa. A diagnosis of SEP, also known as abdominal cocoon, was established based on these features. Additionally, in the abdominal cavity, a large amount of serous ascites and multiple peritoneal nodules or masses involved by DLBCL were recognized. To the authors' knowledge this is the first case report of SEP associated with LC and complicated by the invasion of DLBCL in the abdominal cavity. [source] Radiotherapy for extranodal, marginal zone, B-cell lymphoma of mucosa-associated lymphoid tissue originating in the ocular adnexaCANCER, Issue 4 2003A multiinstitutional, retrospective review of 50 patients Abstract BACKGROUND Due to the small number of patients and differences in the pathologic classification in most radiotherapy series, information regarding the adequacy of tumor control in patients with ocular-adnexal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is limited. METHODS A multiinstitutional, retrospective study was performed on 50 patients with Stage IE ocular-adnexal MALT lymphoma who were treated with radiotherapy between 1989 and 1999. The impact of patient characteristics and other variables on tumor control was analyzed. RESULTS Responses to radiotherapy include a complete response (CR) in 26 patients, a partial response (PR) in 20 patients, and no change in 4 patients. Forty-nine of 50 patients obtained tumor control in the ocular adnexa at 24 months. Overall, 6 patients exhibited disease recurrence at 4,97 months. Three patients developed recurrence in the ocular adnexa. Two patients had isolated extranodal failure involving the oral floor and the submandibular gland, and one patient experienced failure in the neck lymph node. The initial tumor response had a marginal impact on the development of recurrence. None of the 26 patients who achieved a CR experienced ocular-adnexal recurrence. All three patients who experienced local treatment failure belonged to the initial PR group. In total, five of six patients who developed recurrent disease had obtained a PR after initial radiotherapy. Age, gender, tumor location, and dose of radiotherapy did not influence the development of recurrence. There was only one death due to lymphoma. The 5-year overall survival rate was 91% with a median follow-up of 46 months. CONCLUSIONS Radiotherapy offers excellent local control with a prolonged clinical course for patients with MALT lymphoma in the ocular adnexa. The initial response to radiotherapy marginally influenced the probability of recurrence. Cancer 2003;98:865,71. © 2003 American Cancer Society. DOI 10.1002/cncr.11539 [source] Castleman's disease with numerous mantle zone lymphocytes with clear cytoplasm involving the skin: case reportJOURNAL OF CUTANEOUS PATHOLOGY, Issue 8 2009Dario Tomasini Castleman's disease (CD) is an unusual lymphoid hyperplasia occurring in the mediastinal lymph nodes and, less frequently, in the neck lymph nodes. CD is classified clinically into a unicentric and a multicentric type, whereas three histomorphological variants are recognized: the hyaline vascular type, the intermediate type and the plasma cell type. We report the clinical and pathological features of a 54-year-old female suffering with multiple sclerosis and developing a lymph node hyaline-vascular type CD relapsing in the skin after 24 months. Histological features showed a nodular dermatitis with atrophic germinal centers and an ,onion skin' rimming of lymphocytes in the mantle zone with numerous mantle zone lymphocytes with clear cytoplasm, with a CD20+, CD79a+, IgM+, IgG,, IgA,, CD5,, CD10,, CD43,, CD45RO,, bcl-2+ and bcl-6, phenotype with polytypic nature supporting the diagnosis of lymphoid variant of hyaline-vascular CD. This case shows that skin CD recapitulates all the histological variants of lymph node CD. Considering the many similarities between the present case and the primary cutaneous marginal zone lymphoma, it is important to bear in mind this atypical lymphoproliferative disorder in order to avoid overdiagnosis and overtreatment. [source] Medullary thyroid carcinoma as part of a multiple endocrine neoplasia type 2B syndromeCANCER, Issue 1 2002Influence of the stage on the clinical course Abstract BACKGROUND Multiple endocrine neoplasia type 2B (MEN 2B) is an exceptional syndrome, for which the optimal age of thyroidectomy is poorly established and the course of medullary thyroid carcinoma (MTC) is ill-defined. PATIENTS All the 18 patients with a MEN 2B syndrome examined at the Institut Gustave Roussy were included in a single-center retrospective study. RESULTS There were 9 men and 9 women with a mean age of 13 years (range, 2,27 years) at diagnosis. The diagnosis of MTC was based on the presence of a thyroid nodule or involved neck lymph nodes and on dysmorphic features of MEN 2B in 60% and 40% of the cases, respectively. The classic M918T mutation in exon 16 was found in the 16 patients in whom it was investigated. At diagnosis, 2 patients had Stage I MTC, 15 patients had Stage III, and 1 patient had Stage IV disease. T1 MTC was found in 4 patients aged 2.1,3.7 years. However, two of these patients already had N1 disease. One patient with Stage I MTC, aged 3.4 years and 2 patients with Stage III disease, aged 14 and 25 years, had undetectable basal calcitonin (CT) after initial surgery. During follow-up, basal CT became detectable in one of three patients. Among the 15 other patients with an elevated postoperative CT level, metastases were demonstrated in 5 patients after a mean follow-up of 2 years. Five patients died, three of MTC, one of the MEN 2B syndrome, and one of intercurrent disease. Five- and 10-year overall survival rates were 85% and 75%, respectively. CONCLUSIONS This study confirms the need for early treatment of MTC in patients with the MEN 2B syndrome, preferably within the first 6 months of life. The phenotype of MTC occurring in the MEN 2B syndrome was not more aggressive than sporadic MTC or MTC occurring in other familial syndromes. Cancer 2002;94:44,50. © 2002 American Cancer Society.
