Pretreatment lymph nodes, bone marrow, and blood were examined in 176 cases of non-Hodgkin's lymphoma. By the criteria of the Lukes and Collins functional--morphological classification, 158 (90%) were B-cell lymphomas and 17 (10%) were T-cell lymphomas. Bone marrow involvement was present in 53% of cases: 51% of B-cell types and 65% of T-cell types. Marrow involvement was most frequent in small...

Cells from an established line of Burkitt's lymphoma (Daudi) and a mouse myeloma (P(3)K) were pulse-labeled in vitro with (3)H-leucine, and immunoglobulin was immunologically precipitated from cell lysates and secretions. In contrast to P(3)K cells, Daudi cells synthesize a small amount of Ig which is not secreted. Subcellular fractionation experiments indicated that Ig of Daudi cells is synthe...

most bladder tumors are epithelial in origin. nonepithelial cancers are rarely located in the bladder. sarcomas are the most common malignancies among nonepithelial cancers. primary bladder lymphoma is rare and mostly low grade. here, we have reported a case of diffuse large cell lymphoma of the bladder. the patient, a 64-year-old man, had urinary frequency for 18 months. abdominal sonography i...

a forty two years old woman with a history of bilateral breast augmentation for cosmetic reasons was presented for poor healing of the surgical site. tissue and periprosthetic fluid were removed from the wound site revealing an atypical lymphoid infiltrate. subsequently the patient developed axillary lymph adenopathy. excisional biopsy was performed. flow cytometry was non-diagnostic. she conti...

primary non-hodgkin’s lymphoma of the cranial vault is extremely rare. this case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. biopsy revealed a diagnosis of diffuse large b cell lymphoma (dlbcl)...

an 11 year – old mixed female labrador was presented with two masses in trunk and neck. the tumoral masses were excised and sent for histopathological and immunohistochemical analyses. histopathological examination of masses revealed diffuse infiltration of small sized lymphoid cells in subcutaneous tissue which were intense around the blood vessels. more than 10% lymphoid cells were cd3 positi...

Burkitt’s lymphoma is a highly aggressive lymphoma often presenting at extranodal sites or as an acute leukemia. It is synonymous with L3 B ALL in the FAB, small non-cleaved cell, Burkitt’s type in the working formulation (WF). Historically, the prognosis in adults was poor despite early CR rates, however, recently more dose-intense regimens with CNS prophylaxis similar to pediatric regimens ha...
