Since the recognition of Kaposi's sarcoma as a manifestation of the acquired immunodeficiency syndrome, subsequent malignancies such as non-Hodgkin's B-cell lymphoma and primary central nervous system lymphoma have been found to be associated with individuals infected with the human immunodeficiency virus (HIV). The epidemiology, clinical manifestations, and current concepts of pathogenesis are reviewed in this article. In addition, the relation between HIV and other malignancies, including Hodgkin's lymphoma, T-cell lymphomas, and anorectal carcinoma, is discussed. In general, HIV-related malignancies are more aggressive, respond poorly to treatment, and are associated with an extremely high rate of mortality.

The course of disease in 119 HIV-infected patients (117 men, 2 women; median age 38.5 years) with malignant tumours other than Kaposi's sarcoma was analyzed in a multi-centre retrospective study. This was conducted to obtain initial information concerning the incidence, clinical features and results of therapy in HIV-associated neoplasms, especially malignant lymphomas. The most frequent tumour was malignant non-Hodgkin's lymphoma (98 patients, 82.5%), seven patients had Hodgkin's disease, five had solid tumours, four a polyclonal lymphoproliferative syndrome, three an acute lymphocytic leukaemia, and two had other lymphoproliferative diseases. 58% of the non-Hodgkin's lymphomas occurred in patients with marked immunodeficiency, 85% were high grade malignancies and 47% had primary extranodal disease. 56% of primary nodal lymphomas also had visceral spread (Stage IV). Lymphoblastic non-Hodgkin's lymphoma was more common in patients with favourable immunological status, presented less frequently with primary extranodal disease, was diagnosed earlier than other non-Hodgkin's lymphomas, and appeared to carry a better prognosis. 78 out of the 98 patients with non-Hodgkin's lymphoma had been treated, 66 with cytotoxics. The median survival time was 6 months. Longer remission periods, of at least 12 months, were seen in ten of the 78 patients (13%). Despite the overall poor prognosis and the pre-existing immune defect, palliative (chemo-)therapeutic measures are both justified and promising, and may also result in life-prolonging remissions.

The prevalence of dermatologic problems during the course of human immunodeficiency virus infection makes knowledge of these skin manifestations imperative to all practicing dermatologists. Detection of early infection is encouraged as effective therapy now exists both to delay the progression of human immunodeficiency virus-induced immunodeficiency and to prevent opportunistic infections. Skin manifestations of human immunodeficiency virus infection discussed in this article include the following groups: neoplastic, ie, Kaposi's sarcoma, lymphoma, and squamous cell carcinoma; infectious, ie, viral, bacterial, fungal, protozoal, and arthropod infestations; and a miscellaneous group including papulosquamous, papular, vascular, autoimmune, oral, and drug-related skin disorders.

Kaposi's sarcoma (KS) is very unusual in Caucasian women with AIDS. We conducted a retrospective survey of 12 female AIDS patients with KS, including 11 Caucasian women. HIV infection was thought to have been acquired after sexual contact, intravenous drug use (nine cases) or blood transfusion (three cases). In these patients KS was often the first manifestation of AIDS and showed an aggressive course. The disease was associated with a severe immunodeficiency (CD4 T lymphocyte count less than 100 x 10(6)/l in 50% of cases) and a poor prognosis. In four patients, lesions first developed on areas of sexual contact, supporting the hypothesis that KS is a sexually transmitted disease.

We investigated whether elevated serum levels of beta 2-microglobulin and neopterin were related to the abnormal in vivo production of interferon described in patients with human immunodeficiency virus (HIV) infection, and whether these factors might add to measurements of CD4+ T cells in predicting survival and tumor regression in patients with Kaposi sarcoma associated with AIDS. beta 2-Microglobulin and neopterin levels were strongly correlated (r = 0.82), and were each significantly higher in patients with detectable serum interferon-alpha activity. Inverse correlations were observed between prognosis and levels of these serum products. Prediction by CD4+ T-cell count of tumor regression after treatment with interferon-alpha and zidovudine was improved by each of two factors: (a) the presence or absence of endogenous interferon-alpha activity, and (b) a combined variable reflecting relative levels of the interferon-inducible products, beta 2-microglobulin and neopterin. The level of beta 2-microglobulin was the single best predictor of survival. When beta 2-microglobulin was not considered, the endogenous interferon-alpha variable was the best predictor of survival, and the prediction was enhanced by addition of the combined variable, or the neopterin value alone. We conclude that serologic markers, which directly or indirectly reflect activation of the endogenous interferon system, may be valuable adjuncts to CD4+ T-cell counts in assessing prognosis and selecting and evaluating treatments for patients with Kaposi sarcoma and AIDS.

Such aspects are numerous from a disease with multiple factors among them immunodeficiency playing a key-role. O.R.L. aspect are more frequently observed than some ten years ago: this is mainly due to Kaposi's sarcoma in its epidemic form. Nevertheless one has to keep in mind that Kaposi's sarcoma in this endemic african form coexists with its second form without any well-marked border. Finally, many uncertainties are still existing among others its very peculiar cancerous nature.

As the human immunodeficiency virus is being detected in increasing numbers of asymptomatic individuals at risk, newer earlier patterns of disease have become apparent--including cranial and cervical herpes zoster, oral hairy leukoplakia, and oral candidiasis--thus linking viral and other disease to the development of acquired immunodeficiency disease (AIDS). Many similarities between patients with AIDS and other immunosuppressed patients have emerged. As immunosuppressed patients survive longer, they begin to manifest cancers such as lymphomas and squamous cell cancers in addition to Kaposi's sarcoma. Otolaryngologists can learn to identify and treat otitis and sinusitis in the immunosuppressed patient, to identify predictive early signs such as oral hairy leukoplakia, herpes simplex virus, and oral candidiasis, and to diagnose and treat Kaposi's sarcomas of the head and neck, lymphomas, squamous cell cancers, and opportunistic infections as the immunodeficiency disease progresses.

A 56-year-old man was admitted with hemiparesis and shortness of breath. He was positive to human immunodeficiency virus (HIV) antibody and was diagnosed as acquired immunodeficiency syndrome (AIDS) with Kaposi's sarcoma and pneumocystis carinii pneumonia. He developed chronic photosensitivity and vitiligo preceding the onset of the AIDS-related complex (ARC). Association of the two skin lesions with HIV infection is very rare. Although the role of HIV infection in these skin lesions is not significant, the immunological responses in the early course of HIV infection may have contributed to the development of both of these skin lesions.

In an attempt to determine factors predictive of survival in patients seropositive for human immunodeficiency virus (HIV) with acquired immune deficiency syndrome (AIDS)-related lymphoma, the authors studied 60 such patients, all of whom were treated with curative intent. Eleven patients presented with lymphoma primary to the brain (P-CNS); the remaining 49 had systemic AIDS-related lymphoma. Patients with P-CNS lymphoma had more severe underlying HIV-related disease than did patients with systemic lymphoma as evidenced by a higher incidence of AIDS before the diagnosis of lymphoma (73% versus 37%; P = 0.04), and lower median number of CD-4-positive lymphocytes in peripheral blood at diagnosis of lymphoma (30/dl versus 189/dl; P = 0.005). Median survival of such patients was 2.5 months versus 6.0 months for patients with systemic lymphoma (P = 0.04). Forty patients with systemic AIDS-related lymphoma have died; three factors were strongly associated with shorter survival: (1) Karnofsky performance status (KPS) of less than 70% (multivariate relative survival risk [RSR] = 3.1); (2) history of AIDS before the diagnosis of lymphoma (multivariate RSR = 3.0 for opportunistic infection plus Kaposi's sarcoma); and (3) bone marrow involvement (RSR = 3.1)). All three factors (KPS of less than 70%, prior AIDS diagnosis, and marrow involvement) were associated with early demise attributed to AIDS, whereas death attributed to lymphoma per se was associated with only two factors (KPS of less than 70% and marrow involvement). In the absence of all three risk factors, a "good prognosis" group of 17 patients was defined, with a median survival of 11.3 months; the median survival of the remaining patients ("poor prognosis") was 4.0 months (P = 0.0002). Attainment of complete response to therapy (CR) was strongly related to prolonged survival in the patients in the good prognosis group (17.8 months in patients with CR versus 5.0 months in those with less than CR); however, such meaningful prolongation of survival was not seen in patients with poor prognosis who attained CR (6.3 months versus 3.4 months). The patients with poor prognosis may be unable to tolerate the insult of multiagent chemotherapy, experiencing low CR rates (25%) and death caused by lymphoma and AIDS. However, patients in either prognostic category who attained CR remained at risk for dying of AIDS while the lymphoma was in remission. Thus, it is apparent that meaningful prolongation of survival in the patient with AIDS-related lymphoma will require not only effective antineoplastic intervention, but also control of the underlying HIV infection. In addition, future therapeutic trials should stratify patients based upon the prognostic factors defined here in an attempt to clarify the results obtained.

Gastric adenocarcinoma developed in a 33-year-old homosexual man with human immunodeficiency virus (HIV) infection. This type of cancer is very rare in a man of his young age and in the absence of other factors. The tumor was aggressive and led to rapid death. Whereas Kaposi's sarcoma and lymphomas have been associated with HIV, there are only a few documented cases of adenocarcinoma associated with a suppressed immune system. The association between HIV infection and the virulence of this tumor appears to be strong.
