A case of shared paranoid psychotic disorder, with primary diagnosis of persecutory delusional disorder in the husband is described. The delusion and its consequent safety behaviors were so strong that led to the family complete isolation, ceasing their relationship with the external world, gradual starvation and death of the daughter.
