["Folie a deux" in the age of lasers]. / "Folie à deux" im Laserzeitalter.

We report on a 59-year-old teacher suffering for approximately 5 years from multiple dermatological changes, some of which are artificially induced and some of which are imaginary. The patient believes these manifestations are the result of neighbors shooting at her with lasers. Her husband is also convinced of the veracity of these impressions. We interpret her notion of almost daily laser attacks to a skin-related paranoid/hallucinatory psychosis with the involvement of her husband in a "folie à deux".
