Primary cutaneous CD30+ T cell lymphoma is rare lymphoma originally in and confined to the skin. These lymphomas usually present as a large solitary and often ulcerated nodule. Its prognosis is a good and has a good response to radiotherapy. We report a 34- year- old man who had primary cutaneous CD30+T cell lymphoma on his face, which presented as an ulcerated nodule.

Fine-needle aspiration biopsy (FNA) is an accurate and cost-effective procedure for evaluating salivary gland lesions. Lymphoproliferative lesions may manifest as salivary gland enlargement. We report our experience with 43 cases of reactive and neoplastic lymphoproliferative lesions of the salivary glands evaluated by FNA, including 23 cases of reactive lymphoid hyperplasia and 20 neoplastic l...

Morphometric techniques were applied to cytocentrifuge smears from 27 patients with histologically confirmed follicular non-Hodgkin's lymphoma to determine the usefulness of this method in diagnosis. Analysis of quantitative data confirmed that most subtypes were classified correctly on the basis of the proportion of large cells, small cleaved, and large non-cleaved cells, and nuclear, nucleola...

Burkitt's lymphoma is a highly aggressive lymphoma identified and described in the last century by Denis Burkitt in Africa, in areas endemic for malaria. Since its description in African children, it has been recognized outside areas with endemic malaria, frequently also in children as well as among individuals with an underlying immunodeficiency. Since its initial designation as Burkitt's lymp...

Although many recurring chromosome abnormalities have been found in malignant lymphoma (ML) in recent years, their relationship to histology remains largely undefined. We have correlated, in the same tumor mass, chromosome findings with histology, defined by the International Working Formulation for Clinical Usage, in 120 patients. We find differences among histologies in the frequency of norma...

background plasmablastic lymphoma (pbl) is a relatively new entity, classified by who as a rare variant of diffuse large b cell lymphoma. the present case report introduces a 17 year old girl with chronic diarrhea, abdominal pain, intra-abdominal venous thromboses, ascites, mesenteric lymphadenopathies and small intestinal polyposis, the pathologic and immunohistochemistric examinations of the ...

mantle cell lymphoma is an aggressive type of b-cell non-hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. the gastrointestinal tract is the predominant site of extranodal involvement in the form of multiple lymphomatous polyposis. multiple lymphomatous polyposis due to mantle cell lymphoma presenting with intussusception is ...

Non-Hodgkin lymphoma is very uncommon in infancy and skin as the primary site of involvement in Non-Hodgkin lymphoma is rarely encountered. We describe a 10-month-old infant with T-cell Non-Hodgkin lymphoma who presented with multiple skin nodules as the predominant feature of her disease. The clinical manifestations, treatment strategy and disease outcome are reviewed. Key words: Non-Hodgk...

Oral cavity T-cell lymphoma occurs rarely. This case report describes a patient with such a tumor. The case was a 75 years old man presented with a painless swelling on his hard palate mucosa. He had suffered from nose- bleeding and nasal obstruction. Pathology revealed the presence of a T-cell lymphoma tumor in the palate. Though rare, the signs and symptoms of the case suggest that T-cell lym...

To evaluate the effects of polyphyllin D on proliferation and apoptosis human colon cancer SW480 cell lines to reveal whether this process is mediated by micro ribonucleic acid-21/phosphatase tensin homolog deleted chromosome 10 pathway. Human cells were transfected with acid-21-mimic or mimic-negative control treated at different concentrations (control, 0.25, 0.5, 1 2 μM) for 24 h 48 h. Compa...
