[Lichen planus and hepatitis C virus infection. Study of 6 cases].

Lichen planus is an inflammatory dermatosis that has been associated to different chronic hepatopaties with a variable frequency. In recent years several case reports have been published dealing with lichen planus and its association to hepatitis C virus infection. We report six patients with lichen planus (four males, two females; aged 30-75) who also suffered a chronic hepatitis C virus infection. Lichen planus was confirmed by biopsy and viral infection was based on ELISA and RIBA-4 tests in all patients and also on PCR in five of them. A patient had also been diagnosed of porphyria cutanea tarda. Two patients were treated with alfa-Interferon. It did not modify the evolution of their lichen planus. We recommend to search for hepatitis C virus infection in lichen planus patients and also look for lichen planus patients suffering of chronic hepatopathies to improve our knowledge of the possible relation between both diseases.

[Polymicrobial endocarditis: presentation of 3 cases].

We present three cases of polymicrobian endocarditis (PE), two of them in parenterally drug addicts (PDA) and the other one in a central catheter carrier. In all these three cases, the form of clinical presentation was similar to the monomicrobian endocarditis and the valve affected was the tricuspid one, as it occurs in most of the described PE. PE must be suspect in PDA or central catheter carriers if a rare germ is isolated (commensal of skin, oropharynx or gastrointestinal tract) or if there is a poor response to the antibiotic treatment, as it is the case in the patients described here.
