ABSTRACTVaricella is an exantema acute and very contagious, that appears with greater incidence during the childhood. After a period of incubation of 10 to 20 days, the virus scatters itself by the sanguineous torrent towards the skin, which causes rash pruriginous with successive buds of spots and papules that progresses quickly to vesicles, pustules and scabs.
The most frequent complications are the secondary bacterial infections of the skin, produced by staphylococcus and streptococci, those that usually generate impetigo, furunculus, cellulitis, erysipela and rare time gangrene. Four days after the clinical beginning with varicella, a girl of 17 months of age developed necrotic injuries in the neck and the face. The bacteriological culture threw resistant Staphylococcus aureus to the oxaciline.
The virologic diagnosis was confirmed quickly by the cytological examination of the vesicular liquid, the negative tinction for electronic microscopy and the direct immunofluorescence.The Staphylococcus was resistant to oxaciline, the treatment was changed by endovenous vancomicine. After 72 hours the fever disappeared and the necrotic injuries and edema were solved gradually. One discusses to the good use of the microbiological methods and the handling of varicella gangrenous.
