Four young female patients with Pseudodixanthome elasticum are reported, corresponding to the Grönblad and Strandberg syndrome. The dysplastic derangement of the elastic fibers with a potentially systemic compromise is considered, which explains the multiorganic character of the disease. We conferred to the skin changes the means of a marker that obligates an exhaustive study and follow-up of the patients to make visceral affectations.
Two female patients, with similar clinical characteristics, having as only dermatological manifestation large retroauricular plaques, on their surface could be seen many keratinic follicular cysts with an unspecific lichenoid inflammatory reaction. This entity is studied according to the revised bibliography, reaching the conclusion that they are real infundibulo-pilous cysts in plaques, with a very peculiar localisation, which are not red lichen planus. The authors think that this affection should be considered as an autonomous anatomo-clinical entity.
A case of atopic dermatitis with it's classics signs in face and extremities, with an eight years evolution is reported. It was treated with corticoids (local and systemic) with no favorable results. In the allergic investigation it was found a sensibilization to nickel. She was cured by eliminating the nickel from her diet and from the objects in contact. Clinic and etiopathogenic considerations between allergic dermatitis by contact to nickel in the atopic and the non-atopic are made.
A case of sporotrichosis that is inscribed in the localizated cutaneous form of lower incidence in our country, is presented. We destacated its unusual localization and atypical aspect that planteated differential diagnosis of arduous elucidation.
The authors present the case of an 18 years old male patient with a tumor localized in the skin of the nose, which had a fast evolution provoking in a month regional metastases. Histologically it proved to be an alveolar rhabdomyosarcoma. The clinical and histopathological characters are described, and considerations about the origin of this tumor are made.
Twenty eight patients with allergic contact dermatitis were studied by epicutaneous tests, which showed 88 positive reactions. Re-tested 2-3 months later with the same allergen of the positive reactions, 14 were negative (15.9%). This decrease can be due to the Excited Skin Syndrome. The causes which can provoke false positive cutaneous reactions are considered and the inherent to this syndrome, also called "Angry Back Syndrome" are analyzed.
