Varicella is a self-limited disease,but sometimes it may be associated with some serious life-threatening complications.Necrotizing fasciitis is a rare complication of varicella.This is a case of a 7-year-old girl with septic shock caused'by necrotizing fasciitis as a complication of varicella.Swelling and pain in the left inguinal region and left axillary region were found five days after varicella.Then a high fever occurred followed by hypotension.Fluid infusion,vasopressor and antibiotics were administered.Group A beta-hemolytic Streptococcus was isolated from exudates from the wounds.The clinical symptoms markedly improved after surgical drainage and removal of the necrotic tissue.Both wounds were covered with skin grafts after healthy granulation tissue formed.Although there have been few reports of life-threatening necrotizing fasciitis following varicella in western countries,it is rare in China.Usually patients with varicella were admitted to pediatric or infectious disease department but not surgical departments; so that the clinicians should be aware that varicella may be complicated by life-threatening surgical infections.Necrotizing fasciitis should be suspected in patients of varicella who showed an increasing pain and swelling in any body areas associated with increasing fever and local erythema.Early identification,surgical drainage and debridement are essential for successful treatment of necrotizing fasciitis.
