Multifocal lymphangioendotheliomatosis with thrombocytopenia (MLT) is an extremely rare recently described disorder characterized by diffuse congenital skin and gastrointestinal vascular lesions that may be associated with gastrointestinal bleeding and thrombocytopenia. We herein present a case report of multifocal lymphangioendotheliomatosis without thrombocytopenia or extensive extracutaneous involvement (gastrointestinal bleeding). Given the high morbidity and mortality associated with this disease, it is important for clinicians to recognize this disorder in order to select the most appropriate therapeutic approach.
El angiosarcoma es un tumor maligno raro que supone el 1-2% de los sarcomas de partes blandas. Aunque la etiopatogenia no es del todo conocida, se han definido varios factores de riesgo que incluyen el linfedema crónico, antecedentes de radiación, carcinógenos ambientales y determinados síndromes familiares. No hay ningún patrón radiológico patognomónico, por lo que para su diagnóstico es obligada la realización de una biopsia con análisis con técnicas de inmunohistoquímica. El único tratamiento curativo es la cirugía, que puede realizarse en un escaso número de pacientes ya que el diagnóstico suele llegar en estadios avanzados.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
