Erythema endemicum, Lombardy leprosy, elephantiasis italica, dermatagra, maidism, psychoneurosis maidica. An affection characterized by gastrointestinal disturbances, erythema followed by desquamation, and nervous and mental disorders. It is endemic in Spain and Italy and is not uncommon in parts of the United States; it was formerly believed to be an intoxication caused by eating diseased maize, but now believed by many to be a disease of protozoan causation.

A disease, particularly noticed among the Milanese, which consists in the skin becoming covered with wrinkles, and assuming a scaly appearance, especially in the parts exposed to the air. The strength diminishes, the intellectual faculties and sensations become obscure, and cramps, convulsions, and other lesions of muscular contractility supervene. It is a singular endemic affection, and has been supposed to follow everywhere the introduction of Indian corn: hence the name Raphania maiztica, given to it by some of the Italian physicians. An affection endemic in the Asturias is said to be a variety of pellagra. It is the Rosa seu Lepra Asturica, Mai de la Rosa.

Syn.: dermatagra, lombardian leprosy, endemic erythema, malrisso. An endemic trophic disease formerly attributed to eating spoiled maize, but probably caused by the bite of an infected sand fly. It is characterized by gastro-intestinal, cerebrospinal, and cutaneous symptoms. The skin is affected with an erythematous eruption, especially of the exposed parts of the body, and sometimes with desquamation, erosion, or crusting. It comes on rapidly and the eruption is confined to parts which are exposed to the sun. Therefore it is apt to begin on the back of the hands. The digestive derangement may consist of either anorexia, dyspepsia, vomiting, or diarrhea. The nervous symptoms, which are usually grave, may assume the form of either melancholia, mania, convulsions, or idiocy. [Ital.]
