Studies were made on a case of well-differentiated adenocarcinoma of the lung in which the serum levels of secretory IgA (sIgA) were very high. Immunofluorescent studies showed that secretory component (SC) was found to be diffusely distributed in cancer cells. The SC was detected in the supernatant
Five classes of serum immunoglobulin levels were investigated in 107 children with malignant or benign tumors. Hyperimmunoglobulinemia D (hyper-IgD) was observed in 31 of 82 children who were in complete remission off chemotherapy with a median follow-up of 4.5 years after cessation of chemotherapy.
Periodic fever syndrome (PFS) conditions are characterized by recurrent attacks of fever and localized inflammation. This study examined the diagnostic pathway and treatments at tertiary centers for familial Mediterranean fever (FMF), tumor necrosis factor receptor-associated periodic syndrome
An SIV-infected rhesus macaque presented with anemia, hypercalcemia, and hyperglobulinemia. Neoplastic round cells with plasma cell morphology infiltrated multiple organs and stained immunohistochemically positive for CD45, MUM1/IRF4, CD138, VS38C, and Kappa light chain and variably positive for
The adult form of Gaucher disease (type I GD) is associated with a high prevalence of hypergammaglobulinemia and monoclonal gammopathy of undetermined significance (MGUS). A significantly increased risk of cancer, especially of hematological types, has been found in Ashkenazi-Jewish GD type 1
OBJECTIVE
Antiphospholipid antibodies (aPL), anticardiolipin antibodies (aCL) or lupus anticoagulant (LA), are indispensable for the diagnosis of antiphospholipid syndrome (APS). However, antiphospholipid assays can generate false positive results.
METHODS
We have studied the influence of
A 76-year-old female struck her head in the parietal region and noticed a soft scalp mass. Approximately 3 months later, the mass was enlarged and she was evaluated at a local hospital. Although the tentative diagnosis was old subcutaneous hematoma, incision of the scalp revealed not hematoma but
Peripheral blood mononuclear cells (PBM) from a patient with Sézary syndrome exhibiting massive hyperimmunoglobulinemia E were examined in vitro. The patient's PBM and B cells (Bp) but not normal individuals' PBM and B cells (Bn) produced spontaneously large amounts of IgE. The addition of pokeweed
The neoplastic T cells of a series of seven patients with chronic T-cell neoplasia were tested for helper activity on pokeweed mitogen (PWM)-induced and interleukin 2 (IL-2)-induced Ig synthesis. The neoplastic T cells of all patients had a T3+4+8-11+I1- phenotype but differed in expression of the
The case of a 14-year-old boy presenting with hypergammaglobulinemia (immunoglobulin (Ig)G and IgA) and a cerebellopontine angle tumor is reported. The tumor was histologically confirmed as meningioma infiltrated with plasma cells, lymphocytes, and histiocytes. Immunohistochemical studies showed
OBJECTIVE
To investigate the clinical and laboratory characteristics of tumor like Sjögren's syndrome (TLSS) patients and non-tumor like Sjögren's syndrome (NTLSS) and the incidence of lymphoma in patients of Sjögren's syndrome (SS).
METHODS
A retrospective analysis was carried out in 199 primary SS
A 73-year-old male was admitted in January 1999 with hyperimmunoglobulinemia with a serum IgG level of 6530 mg/dl, bilateral eyelid tumors, bilateral submandibular swelling, and swelling of the superficial lymph nodes. A left submandibular gland biopsy showed severe chronic sialoadenitis with
The association of adenopathies, having sometimes a tumoral aspect, and a polyclonal hypergammaglobulinemia in the blood can be observed in various illnesses. In all these diseases the increase in the volume of the lymph nodes is partly due to the hyperplasia of the lymphoid B regions. Lymph node
