[An unusual case of "acute abdomen". Dimethylformamide poisoning].

Dimethylformamide, an industrial solvent largely used, causes intoxication both by inhalation and cutaneous adsorption. The Authors report the case of a young worker suffering from abdominal pain and hepatopathy who was heavily exposed to the solvent. A first diagnosis made by the surgery department was that of acute cholecystitis without gallstones. In the three successive years the worker was controlled and did not show relevant consequences of intoxication.
