Blistering Distal Dactylitis

Excerpt

Blistering distal dactylitis (BDD) is a localized bacterial infection manifesting as fluid-filled lesions over the fingers especially in children. Classically, BDD is localized to the volar fat pad of the distal phalanx of the digits presenting as a medium to large non-tender blister filled with a thin, white fluid. Bacterial cultures from this fluid most commonly grow group A beta-hemolytic Streptococcus. Hays and Mullard originally described BDD in 1972.
