In 1998 and 1999, we diagnosed avascular necrosis of bone in 6 patients in our human immunodeficiency virus clinic practice, an incidence of 0.45%, which is 45 times greater than would be expected in the general population. Antiphospholipid antibodies and hyperlipidemia secondary to protease inhibitor therapy have been implicated as possible etiologies; however, these abnormalities cannot expla...

Patients with the acquired immunodeficiency syndrome are at risk to develop a variety of different cancers. Based on epidemiolÃ3gica! data, Kaposi's sarcoma and non-Hodgkin's lymphoma have been clearly asso ciated with infection by the human immunodeficiency virus (HIV). Ad ditional cancers such as basal cell and squamous cell carcinomas, mela noma, and hepatocellular carcinoma have also been r...

The life span of patients with primary and secondary immunodeficiency is increasing due to recent improvements in therapeutic strategies. While the incidence of primary immunodeficiencies (PIDs) is 1:10,000 births, that of secondary immunodeficiencies are more common and are associated with posttransplantation immune dysfunction, with immunosuppressive medication for human immunodeficiency viru...

Kaposi's sarcoma (KS) is a malignant vascular neoplasm that typically appears opportunistically in patients with acquired immunodeficiency syndrome (AIDS); it can also arise organ transplanted subjects and exceptionally carriers of autoimmune diseases, such as Behçet's disease. A 23-year-old man disease who debuts clinically histologically compatible dermatosis KS. Conclusions. KS not exclusive...

Syphilis is considered one of the greatest imitators which can mimic any skin disease. Keen examination together with a sound brain and high degree suspicion required for its diagnosis. Syphilis, sexually transmitted disease caused by spirochete Treponema pallidum pallidum, was more common during Second World War. Later, as human immunodeficiency virus cases increased, there increased,incidence...

Epstein-Barr virus (EBV) is a ubiquitous DNA virus that normally infects silently, establishing lifelong latency. Substantial empirical observations support the view that immunodeficiency is permissive in EBV-induced lymphoproliferative diseases (LPD). Primary immune deficient patients such as those with X-linked lymphoproliferative disease and individuals with acquired immune deficiency second...

Patients with the acquired immunodeficiency syndrome are at risk to develop a variety of different cancers. Based on epidemiological data, Kaposi's sarcoma and non-Hodgkin's lymphoma have been clearly associated with infection by the human immunodeficiency virus (HIV). Additional cancers such as basal cell and squamous cell carcinomas, melanoma, and hepatocellular carcinoma have also been repor...
