[Medical certificates and the new firearm regulation in France]. / Certificats médicaux et nouvelle réglementation des armes à feu en France.

France has adopted a new firearms regulation. Firearms are now classified into four categories (A, B, C, and D). The administrative procedure for acquisition and possession of firearms of categories B and C requires medical advice. The medical certificate must be dated less than a month, and detail a state of health compatible with the acquisition and possession of a firearm. There are no guidelines mentioning the conditions that can lead to incompatibility. Compatibility does not apply to the handling and use of the firearm. If the applicant is undergoing or has undergone treatment in a psychiatric institution, he must also produce a medical certificate issued by a psychiatrist. The hunting license application requires a medical certificate mentioning a state of physical and mental health compatible with the possession of a firearm. Its validity is acquired for life. The practice of shooting sports or skeet requires an annual medical certificate of non-cons in reference to the rules of sports federations.

Tufted angioma with Kasabach-Merritt syndrome mistaken for child abuse.

We report the case of a 2-month-old infant with a single apparently ecchymotic lesion on the shoulder that raised suspicions of abuse. The medicolegal examination concluded that the appearance of the lesion was only mildly suggestive of an ecchymosis. A second, temporally remote examination confirmed this doubt. The evolution of the lesion, notably an increase in its volume, allowed us to rule out a traumatic lesion and was suggestive of a vascular tumor. The histological type of the tumor was a tufted angioma. There was thrombocytopenia and consumptive coagulopathy. All these data confirmed the diagnosis of Kasabach-Merritt syndrome. In contrast to benign infantile hemangiomas, which are frequent and well-known in clinical practice, vascular tumors complicated by Kasabach-Merritt syndrome are rare. They deserve to be widely known because they mandate rapid medical management and because they are one of the only differential diagnoses of ecchymosis, especially in children. When there is doubt about the traumatic nature of a cutaneous lesion, a temporally remote examination is essential. The evolution of the lesion may then suggest a dermatologic origin.
