Dermatitis repens has many names, including acrodermatitis continua of Hallopeau. François Henri Hallopeau, an accomplished French dermatologist in 1800s, discovered this condition and named it after himself as "Hallopeau Syndrome II."
Definition
Dermatitis repens is a rare, non-contagious, chronic, sterile, localized pustular eruption of the fingers and toes. It can spread, eventually covering the hands or feet and causing deformation or loss of toenails and fingernails.
Cause
Acrodermatitis continua of Hallopeau is typically initiated by a localized trauma or infection on a single finger or toe, although it may also be caused by a staphylococcal (bacterial) infection.
Prevalance
Dermatitis repens most commonly affects middle-age to elderly women, but anyone can contract this disease.
Treatment
Dermatitis repens is typically difficult to treat. Standard treatment starts with a steroid based ointment, followed by oral drugs if needed. For severe cases, PUVA (Psoralen and UVA treatment) will be used.
Connection to Psoriasis
The Psoriasis Association reports that dermatitis repens is a rare type of pustular psoriasis, an uncommon skin condition. Treatments for both conditions are very similar.
