[Angioblastoma (hypertrophic hemangioma). Preliminary report].
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.
