[Congenital psoriasiform erythroderma with bullous eruptions].

A 39 years old female patient with congenital erythroderma is reported. The condition was considered as the non bullous type of Brocq's congenital ichthyosiform erythroderma until recently. The patient was admitted as she had generalized erythema, desquamation and oedema, pyrexia and oliguria. The scales were fine and small, quite different from those of lamellar ichthyosis. The patient developed a recidivant pustular eruption on palms, face and trunk. So the diagnosis was changed to congenital psoriasiform erythroderma and this was supported by histopathological examination of both scaling and pustular lesions. There was a remarkable improvement on amethopterin therapy. The case is discussed and the relevant litterature is reviewed.
