A case of mandibularis tori, lobular type is reported. Tori appear more frequently during middle age; it is well known in the dental literature but rarely mentioned in the dermatological one.

We report a case in which a 21-week pregnant woman was stung by a Euscorpius flavicaudis (De Geer, 1778) scorpion. Symptoms and signs experienced by the patient were the same as those documented in the literature and with no ill-effects for the pregnancy. Envenoming was local and of low degree of intensity. It is important to emphasize that the patient was stung in her home, which differs from stings in most other parts of the world, in which scorpionism is mostly a risk in outdoor areas.

In the period between June 2008 and August 2009, three cases of stings of Euscorpius scorpions indigenous to Italy were treated at two different emergency departments (ED) in hospitals of the Piedmont region, northwest Italy: Santa Croce e Carle General Hospital in Cuneo, and Santissima Annunziata Hospital in Savigliano. Scorpion stings in Italy are rare and not well documented in the literature; this situation may raise doubts among medical personnel as to how such lesions are best treated. Analysis of the incidents confirms that the venom of Euscorpius do not provokes systemic poisoning in humans and in these cases even dermatological reactions were not significant.
