Achenbach's syndrome corresponds to a pathology characterized by the appearance of ecchymoses and bruises on the fingers of the hands and eventually on the feet. It is a benign and self-limited disease, which is accompanied by pain. It generates great concern because its sudden appearance leads women who are the most affected to consult the emergency services. At present, its pathophysiology is unknown and requires knowledge of the disease to diagnose it. It is a must for poorly trained professionals.
