Bulla repens L03.01

Acute, vesicular, superficial form of an acute paronychia. Bulla repens can also be described as a special form of (blistered) Impetigo contagiosa on the groin skin.

Staphylococcus aureus, rarely strep.

The clinic of bulla repens, as pyoderma of the groin skin, is defined by the anatomical peculiarity of the groin skin. The purulent exudation of the dermis leads to a subepithelial pustule with a "thick" stratur corneum forming the cover. Since this does not burst in contrast to the thin field skin, the exudation can only migrate subepithelially. A large, bulging pus blister is formed. At the tip of the finger or toe there is a "circulating" blister which is in reality a pustule.

Mostly solitary, mostly turgid blister surrounded by an inflammatory cavity with initially clear contents, later purulent clouding (pus blister). There is a tendency to grasp the nail (circulation). Possible involvement of the nail fold and bed with loosening or detachment of the nail.

• Opening of the bladder, removal of the bladder cover, baths with aqueous quinolinol solution(e.g. Chinosol 1:1000), R042, diluted potassium permanganate solution (light pink), ointment therapy with iodine-polyvidone ointment (e.g. R204, Braunovidon).
• Apply sterile dressings with gauze grid (e.g. Hansaplast), if necessary use gauze grid with antibiotic additives (Fucidine gauze, Branolind). Removal of ointment residues with iodine-polyvidone solution (e.g. Braunoderm).
