A consumption coagulopathy is presented, featuring a chronic and localized intravascular coagulation syndrome, with cutaneous manifestations exclusively, associated to an aortic aneurysm. The infrequency of this association is remarkable, being assumed as capital factors from the physiopathogenic side the parietal alteration and the blood stasis. They both determine the consumption of platelets adding further thromboplastic material that maintains the process.

Two patients with idiopathic generalized livedo reticularis and associated cerebrovascular disease are reported. In one of the cases (case no. 1) skin vascular lesions were present in two members of the family, thus suggesting the existence of a possible predisposition to systemic vascular affection. The need of prevention of the neurological symptoms in patients with generalized livedo reticularis, through the exclusion of the nocive agents which can cause vascular damage is emphasized.

A 31 years old woman had an exanthematic eruption of small and acral distributed papules. At the same time she suffered a clinical and biological hepatitis B. This case is described attending to the clinic, histopathology and direct immunofluorescence. By the way the Gianotti-Crosti syndrome is reviewed.

We report a patient that fulfills the clinical features of inflammatory bowel disease (Crohn) who develops papulopustular lesions, some of which evolve into erythematous plaques with pustules and other into superficial ulcers. The different cutaneous manifestations of inflammatory bowel disease, are reviewed, an entity which includes Crohn's disease and ulcerative colitis, as well as the previously reported cases which developed papulopustular lesions emphasizing their similarities and their differences to our patients and also its probable relationship to malignant pyoderma.

A patient (gastronomic employee) presented a sharp dermatosis of eczema type in both hands. Patch-test confirmed sensitivity to heterologous proteins contained in the squid, which he was accustomed to handling. Although the levels of the IgE were elevated, the final diagnostic was dermatitis by allergic heterologous proteins.

The authors study three clinical cases of Pacinian neurofibromas. All of them were located in the fingers. A bibliographic review was performed. The morphologic, clinical and histological features are reviewed and stressed its benign behavior and special localization.

A patient with true allergic contact dermatitis produced by gold is described. A lady suffered of a contact allergic vesiculous dermatitis in the proximal root of a finger provoked by her wedding ring, and also when worked in a metal factory touching all kinds of metals, including gold, an acute vesiculous eczema of hands and fingers appeared, promoting the study in our Service. For our knowledge this is the first well documented case of allergic contact dermatitis described in Spain. The specificity of the path test with sodium thiosulfatoaurate 0.5% in Pet was very useful for the study of this allergy.

Our study included children up to 15 years of age who were selected from an open population. We found a frequency of 3.4% and it ranked 3rd among the most common dermatoses. The age range varied between 1 year 9 months to 15 years. In only one case we found an important predisposing factor (lupus erythematosus which was treated with systemic steroids). It is concluded that this dermatosis is not as infrequent as it seems.

alpha-2A-interferon is a useful and safe drug in Kaposi's sarcoma treatment although not free of serious side-effects when used at therapeutic dosages by which strict controls must be undertaken. When treatment has been interrupted, worsening and dissemination of the disease happened. No correlation has been found between immunologic parameters and the treatment used.

We are presenting herewith the case of a rare vascular tumor called angioblastoma which histopathological and clinical aspects may lead into errors of diagnosis and therapy. Its fast development, tendency to ulceration and bleeding and dark colour, are signs that may be confused with those of hemangiosarcomas and, inclusive, melanomas, because, from a clinical point of view, its pleomorphism and cellular atypical nature, due to immaturity, may induce diagnostic and histological doubts. In order to simplify diagnosis and therapy of an angioblastoma, we have treated it within the complex subject of vascular hyperplasias in general. Thereby, we have made three synopses of interest for such a purpose. Out of the consulted bibliography, its limited frequency is stated, as relative cases don't amount to a hundred worldwide and none of them was found in our country. We have reported the most accurate data for its correct clinical and histopathological diagnosis to avoid extremely aggressive therapies, since it is a lesion of benign biological behaviour.
