[Extrapulmonary and disseminated pneumocystosis in AIDS. A review of the literature].

We present a literature review about extrapulmonary and disseminated pneumocystosis in AIDS. The prevalence of such infections seems low but is probably under-estimated. Disseminated pneumocystosis occurs in patients with profound immunosuppression, who do not receive prophylaxis against Pneumocystis carinii pneumonia or are treated with aerolized pentamidine. The lack of specificity of symptoms may delay the diagnosis. Most organs may be involved. Three different presentations may be individualized: disseminated pneumocystosis, intra-thoracic only disseminated pneumocystosis, in an intra-thoracic localization alone, and localized extrapulmonary pneumocystosis. The mortality from disseminated disease is high, especially in the presence of low serum albumin level.
