Impetigo herpetiformis (two cases)

The hepetiformis impetigo is a pustulosis dermatosis. It is rare and specific to pregnancy. It can menace the prognostic of the mother and the child. This entity is actually considered as a pustulor psoriasis. We report two cases. Two patients, respectively, aged 24 and 21, presented erythematous, pustular and extensive plaques for which the diagnosis of hepetiformis impetigo was clinically and histologically posed. For the first patient, the lesions appeared in the two pregnancies and were more severe and foetal repercussions (oligoamnios and hypotrophy) during the second pregnancy. For the second patient, the pregnancy was complicated with premature interruption of the membrane, giving birth to a deed fetus and causing an aggravation of the cutaneous lesions. The treatment was oral steroid followed by acitretin for the first patient, however, for the second patient; the treatment was by local steroid associated with UVB during the pregnancy. Then, acitrétine was used and was efficient. Our two cases show the importance of gynaecological control in order to avoid complications which can be sometimes fatal. They also show the importance of local steroid associated with UVB which constitute another therapeutic alternative in the treatment of hepetiformis impetigo.
