Recent polymerase chain reaction (PCR)-based studies focused on the detection of immunoglobulin heavy chain gene (IgH) rearrangements have suggested that clonal populations may be amplified more easily from certain categories of B-cell neoplasia than others and that primer makeup can be a critical factor in successful amplification. However, these(More)
The presence of occult bone marrow metastases (OM) has been reported to represent an important prognostic indicator for patients with operable breast cancer and other malignancies. Assaying for OM most commonly involves labor-intensive manual microscopic analysis. The present report examines the performance of a recently developed automated cellular image(More)
Using an antibody to the nerve growth factor receptor (NGFR), we examined dendritic reticulum cells (DRCs) immunohistochemically in 62 formalin-fixed, paraffin-embedded lymph nodes from patients with reactive follicular hyperplasia or with various types of lymphoma. A dendritic staining pattern within germinal centers was present in 25 of 26 routinely(More)
Mantle cell lymphomas (MCLs) are typically CD5-expressing B-cell non-Hodgkin's lymphomas (NHLs) that frequently harbor the chromosomal translocation t(11;14) or bcl-1 gene rearrangements. Insufficient data are available on the biologic features and clinical behavior of rigorously characterized MCL. As these NHLs have been reported to exhibit various(More)
Flow immunophenotyping, DNA content analysis, and polymerase chain reaction (PCR) amplification for t(11;14) and t(14;18) were performed on 11 cases of typical mantle cell lymphoma (MCL), 5 cases of apparent MCL with proliferation centers (MCL-PC), and 5 cases of small lymphocytic lymphoma (SLL). Immunophenotyping showed IgM (P < .001), Ig light (P < .001),(More)
The relationship of various verruciform squamous cell proliferations of the penis such as verrucous carcinoma, with or without anaplasia and giant condyloma, is uncertain. We conducted clinicopathologic, flow cytometric, and HPV typing studies on 15 cases of penile verrucous carcinoma to investigate its place in the spectrum of genital squamous(More)
Cytomegalovirus (CMV) is a common cause of lower respiratory tract infections in immunocompromised individuals. Bronchoalveolar lavage (BAL) is a noninvasive means to procure large numbers of bronchial and alveolar cells from the lung. To assess various methods of detecting CMV in the lavage specimen, 26 BAL specimens from 16 patients at high risk for CMV(More)
Forty-two patients with advanced-stage nodular sclerosing Hodgkin's disease (NSHD) were treated uniformly with combination chemotherapy and radiation therapy at the University of Nebraska Medical Center between 1982 and 1987. The cases were subclassified into low-grade (13 cases) and high-grade (29 cases) categories using the British National Lymphoma(More)
To investigate the issue of clonality in Richter's syndrome, phenotypic, molecular genetic, and cytogenetic studies were performed on tumor tissue from a patient with concurrent chronic lymphocytic leukemia and diffuse large cell lymphoma in a single lymph node specimen. The tumor was biphenotypic for immunoglobulin (Ig) expression with surface Ig(More)
Many nonrandom chromosome abnormalities have been associated with non-Hodgkin's lymphomas (NHL). Some of these are nonspecific changes seen in many different histologic subtypes. We describe a series of abnormalities of chromosome bands 10q23-25 seen in 159 consecutive NHL patients with abnormal cytogenetic findings. The proportion of karyotypes with(More)
