[Actinic porokeratosis in a family. Bibliographic review compared with Mibelli's porokeratosis].
In our study we try to differ two dermatological diseases that, usually, are very confused. These diseases are the Disseminated Superficial Porokeratosis of Mibelli, also called of Respighi, and the Disseminated Superficial Actinic Porokeratosis (DSAP). After a review of the published material, we have ascertained that the difference between these dermatosis are above all, clinical. The most important is the age, topography, sun influence and possibility of degeneration. We include in our work a comparative clinical table with all the data that clearly identifies the difference between both diseases. We present six typical cases of DSAP with autosomic dominant inheritance binding female sex. The histopathologic study shows a parakeratosic cone, under it the granular layer disappears; we can see in the spinous layer, cells with picnotic nuclei and perinuclei oedema. These cells are the base of a parakeratosic cone.
