Blistering Distal Dactylitis is a skin infection caused most often by group A beta-hemolytic streptococcus or, rarely, group B beta-hemolytic streptococcus or Staphylococcus aureus.

Signs and Symptoms

Tender superficial bullae occur on the distal volar finger pads or, less often, the toes; erythema usually surrounds the bullae.

There is generally an absence of systemic symptoms.


The diagnosis is usually made based on the clinical findings. Gram stain or bacterial culture of the bulla is often confirmatory.


Drainage of the bullae can decrease pain if it is present.

Oral antibiotics is usually used to treat the infection.
