Pulmonary toxoplasmosis in human immunodeficiency virus-infected patients in the era of antiretroviral therapy.

Toxoplasmosis is a severe opportunistic infection in patients infected with the human immunodeficiency virus (HIV). The lung is a major site of infection after the central nervous system. In this report we described two cases of pneumonia due to Toxoplasma gondii infection in HIV patients with antiretroviral therapy.

[Rhodococcus equi infection in AIDS patients: retrospective analysis of 13 patients in Argentina].

Introduction: Rhodococcus equi is a gram positive coccoid rod that causes pulmonary infections in immunosuppressed patients.

Methods: We retrospectively analyzed epidemiological, clinical, microbiological, radiological, and immunological features as well as the outcomes of 13 AIDS patients with R. equi infection.

[Brunner's gland adenoma: a rare tumor as cause of pyloric syndrome in an AIDS patient].

Brunner's gland adenoma is a rare neoplasm that accounts for only the 0.008% of all benign duodenal tumors. Here we describe the case ofan HIV-seropositive man who developed a severe pyloric stenosis due to a Brunner's adenoma of the bulb and the first duodenal portion.

[Malignant syphilis in a patient infected by human immunodeficiency virus. Case report and literature review].

Malignant syphilis is a rare form of secondary syphilis strongly associated with human immunodeficiency virus infection (HIV). This clinical form of the disease is characterized by atypical cutaneous ulcerative and disseminated lesions and systemic compromise that can delay the final diagnosis. There are only few reports in the medical literature about malignant lues in HIV-infected patients.

Candida parapsilosis meningitis in a patient with AIDS. Report of a case and review of the literature.

Background: Candida parapsilosis is an important species in the genus Candida that plays a significant role in hospitalized patients with nosocomial infections. In patients with HIV infection or AIDS, central nervous system involvement by Candida species is exceptional.

Case Report: Here we report a case of an acute meningoencephalitis due to C.

Non-Hodgkin lymphomas of the oral cavity in AIDS patients in a reference hospital of infectious diseases in Argentina: report of eleven cases and review of the literature.

Introduction: Extranodal non-Hodgkin lymphoma (NHL) were commonly described in AIDS patients and are related with an atypical morphology and aggressive clinical course.

Materials And Methods: In this single institutional study we evaluated the epidemiological, clinical, immunological, virological, histopathological and the outcome of eleven HIV/AIDS patients with oral cavity lymphomas (OCL).

Results: Nine were males and seven intravenous drug abusers.

Non Hodgkin's lymphoma with cutaneous involvement in AIDS patients: report of five cases and review of the literature.

Cutaneous B cell lymphoma (CBCL) is a lymphoproliferative disorder of neoplastic B cell of the skin with a wide range of clinical manifestations. Commonly, the clinical features of CBCL are plaques, nodules, or ulcerative lesions. Skin is one of the common sites for extra-nodal lymphomas in patients with AIDS and B cell type is less common than T cell type.

Disseminated nocardiosis with psoas abscess in a patient with AIDS: first reported case.

Psoas muscle abscess is an uncommon infection that have been diagnosed increasingly in the last years. We present a case of a patient with advanced human immunodeficiency virus infection who developed a disseminated infection due to Nocardia asteroides sensu stricto type VI with psoas abscess. To our knowledge no other cases of Nocardia psoas abscess in the setting of HIV infection have been reported in the literature.

Oral cavity lymphoma as secondary AIDS-defining neoplasm in a patient on HAART with immune reconstitution.

Lymphomas of the oral cavity are a rare complication of advanced HIV/AIDS disease. The clinical appearance of these neoplasms includes masses or ulcerative lesions that involve the oral soft tissue and the jaw as the predominant manifestation. We report the case of a patient with AIDS who developed diffuse large B-cell non-Hodgkins lymphoma of the oral cavity during highly active antiretroviral therapy, with undetectable plasma viral load and immune reconstitution.
