hypergammaglobulinemia/sarcoma

Granulocytic sarcoma (GS), is an extramedullary tumorous aggregate of neoplastic myeloid precursor cells, most often associated with acute myeloid leukemia (AML). Primary GS occurs in patients with normal bone marrow and no history of hematological disorders. It is a rare disease, which can involve

Within the Lukes-Collins classification system of malignant lymphoma, a tumor of large transformed lymphocytes, termed immunoblastic sarcoma (IBS), is described. This morphological type would have been included within the "histiocytic" category of Rappaport. Immunoblastic sarcoma may be of

A case of immunoblastic sarcoma in a 56-year-old man is presented. He had no history of predisposing diseases. His clinical condition was typical of a highly aggressive disseminated malignant lymphoma and he presented important heterogenous hypergammaglobulinemia. The patient died 9 months after the

Besides the AIDS-related form of Kaposi sarcoma (KS) there are few well-known aggressive types of this disease. These non-epidemic invasive variants of KS have been recognized in young black males of equatorial Africa and in renal transplant recipients after iatrogenic immunosuppression. We report

Positive direct antiglobulin results prior to transfusion in some of our AIDS patients, as well as some reports in the literature on red cell antibodies in AIDS patients, prompted us to investigate the prevalence of erythrocyte antibodies in AIDS patients with transfusion requiring anemia. In

Human herpes virus 8 (HHV-8) or Kaposi sarcoma-associated herpes virus is the etiologic agent of Kaposi sarcoma, primary effusion lymphoma, and plasma cell-type multicentric Castleman disease (MCD). HHV-8 encodes a viral homolog of human IL-6, called viral IL-6 (vIL-6), which does not require the

We report the case of 43-year-old homosexual patient with HIV infection and a history of travel to the Far East in whom visceral leishmaniasis was the first infectious complication. Symptoms were fever, malaise, weight loss, hepatosplenomegaly, generalized lymphadenopathy, and oral thrush.

We report 31 cases of AIDS-Kaposi's sarcoma (KS) studied at the Hôpital Saint-Louis, Paris, France, from January 1983 to January 1986. Twenty-nine cases were cutaneous KS and 2 were lymph-node KS. Twenty-eight patients were homosexual or bisexual males, 1 was a woman with transfusion-AIDS and 1 was

The objective of this study is to systematically review the epidemiology and the clinical and virologic aspects of multicentric Castleman's disease in HIV-positive patients and to evaluate treatment strategies and outcome, especially in relation to HAART administration. The authors have conducted a

Inflammatory myofibroblastic tumors (IMT) are rare, benign lesions. They mimic, clinically and radiologically, malignant tumors-especially sarcoma. IMT most often are seen in the lung of young adults, but there have been reports of these tumors occurring in children, in various sites. The authors

Twenty-five cases of acquired immune deficiency syndrome (AIDS) complicated by opportunistic infections were diagnosed at Lenox Hill Hospital during an 18 month period and followed for at least 1 year or until the patients' deaths. Twenty-three patients were homosexual men, including 1 i.v. drug

Some immunologic diseases are characterized by profound loss or primary dysfunction of a given population of cells. The atypical cellular disorders discussed here all bear some similarities in that abnormal proliferations of lymphocytes and macrophages or dendritic cells result in lymphadenopathy,
