Gianotti-Crosti syndrome preceded by oral polio vaccine and followed by varicella infection.

Gianotti-Crosti syndrome (papular acrodermatitis of childhood) is considered a nonspecific cutaneous host response to a variety of infectious agents, particularly viruses. Herein we report a case of Gianotti- Crosti syndrome preceded by oral polio vaccine and followed by varicella infection. The present case may support the hypothesis of initial immunization and following viral infection as a possible mechanism for Gianotti-Crosti syndrome.

Combined vaccination by measles and hepatitis B vaccines: a new cause of Gianotti-Crosti syndrome.

An 11-month-old boy presented with Gianotti-Crosti syndrome. He had received measles and a third dose of hepatitis B vaccines 2 weeks before the onset of the eruption. There were no clinical symptoms of any viral infection at the presentation.

Disseminated pagetoid reticulosis: plaques and tumoral lesions occurring simultaneously in the same patient.

Disseminated pagetoid reticulosis is considered to have a poor prognosis. Some authors regard this disease as an epidermotropic type of mycosis fungoides rather than a distinct entity. We report the case of an 83-year-old woman with disseminated pagetoid reticulosis who subsequently developed tumoral lesions and died soon after the appearance of these tumours.
