Eleven patients with infantile acropustulosis, 10 from Mendoza and one from Buenos Aires, are presented. Remarkably was a blood eosinophilia in 4 cases and the prompt improvement with dapsone in 2 cases. The differential diagnosis with other dermatosis, specially with scabies, are discussed.
We present a 66 years old patient with bullous pemphigoid which appeared two years before a lymphoblastic lymphoma. According to the bibliography, there appear to be a causal relationship between lymphoma and pemphigoid.
The name epidermal nevus syndrome could be applied to a group of clinically and histopathologically different entities as has been pointed out by Happle. Phacomatosis pigmentokeratotica is a further type of epidermal nevus syndrome distinguished by the presence of a sebaceous nevus and a contralateral speckled lentiginous nevus of the papular type, associated with skeletal or neurological abnormalities. Three new cases of this recently delineated syndrome are presented. A common origin may account for the temporal and spatial relationship between the epidermal and the speckled lentiginous nevus. The concept of melanocytic-epidermal twin spotting similar to the interpretation of vascular twin spotting could explain the pathogenesis of this entity.
