Review Case Reports[Listeria monocytogenes infection in HIV patients: 2 new cases].
Two new cases of infection due to Listeria monocytogenes in two females with HIV are discussed, one of them with full blown AIDS and the other pregnant and without knowledge of her seropositivity until that moment. Its clinical manifestation as a meningeal manifestation and bacteremia, coincide with the few cases described until now; different hypothesis invoked until now are reviewed to justify this infrequent association HIV-Listeria.

Case Reports[A toxic syndrome and subcutaneous nodules as the only clinical manifestation of systemic sarcoidosis].
Sarcoidosis is a systemic disease with frequent cutaneous manifestations. Among these exists a predominance of the so-called unspecific lesions because of their histopathological features. Within the specific lesions, that is those which showed non-caseous granulomas, subcutaneous nodules are underlined, which have been associated with chronic sarcoidosis with a frequency of 1.4%-6%. ⋯ Histopathological study of these nodules showed the existence of non caseous granulomas formed by histiocytes, epithelioid cells, Langhans and foreign body giant cells. Lobulet hepatic granulomas were showed together with mediastinal pulmonary captation of gallium. We conclude that sarcoidosis must be considered when performing the differential diagnosis of the disease which debut with subcutaneous nodules.
