Blistering distal dactylitis caused by Staphylococcus aureus.

Blistering distal dactylitis is a superficial infection of the anterior fat pad on the volar surface of the distal portion of ordinarily a single finger. Although most commonly caused by group A beta-hemolytic streptococci, we report a case of blistering distal dactylitis caused by Staphylococcus aureus involving all the fingers and thumbs of a child. After results of a Gram's stain and culture established the diagnosis, the child responded rapidly to oral amoxicillin trihydrate/clavulanate potassium (Augmentin). Multiple fingers affected in blistering distal dactylitis may be a predictor of S. aureus as the causative agent.
