          Abstract

          Resumen La hiperplasia endotelial papilar intravascular (IPEH) es una lesión vascular benigna poco frecuente que se presenta habitualmente como una neoformación subcutánea eritemato-violácea inespecífica. El estudio histopatológico, necesario para el diagnóstico de confirmación, muestra proliferación papilar de células endoteliales asociada con material trombótico. La IPEH puede simular otras lesiones como el angiosarcoma, por lo que el diagnóstico correcto de esta entidad es esencial para evitar tratamientos agresivos. La resección con márgenes amplios suele ser suficiente.

          Abstract Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign vascular lesion that usually presents as a nonspecific erythematous-violaceous subcutaneous neoformation. The histopathological study, necessary for the confirmatory diagnosis, shows papillary proliferation of endothelial cells associated with thrombotic material. IPEH can simulate other lesions such as angiosarcoma, so the correct diagnosis of this entity is essential to avoid aggressive treatments. The resection with wide margins is usually enough.

          Intravascular papillary endothelial hyperplasia. A clinicopathologic study of 91 cases.

          Ninety-one cases of intravascular papillary endothelial hyperplasia were studied clinically and histologically. This peculiar benign process, occasionally resembling hemangiosarcoma, was subgrouped in the following categories: a pure form that occurs within a dilated vascular space (30 cases), a mixed form that appears as a focal change in a hemangioma (55 cases), a third form (six cases) that belongs to neither of the first two. In the pure form, the lesions were most frequently situated in the subcutis of fingers (14 cases), of the head and neck (seven cases), and in the region between the elbows and hands (six cases). In the mixed form, half of the accompanying hemangiomas were intramuscular in no particular predilective sites. Papillary proliferation of endothelial cells was commonly found to be closely associated with thrombotic material and seemed to be an unusual feature of a thrombus undergoing organization.

            Intravascular papillary endothelial hyperplasia of the jejunum: an unusual cause of melena.

            Intravascular papillary endothelial hyperplasia is considered to be an unusual form of thrombus organization that is marked by an excessive papillary endothelial proliferation. This lesion has the propensity to occur in the skin and the subcutis. Occurrence in the gastrointestinal tract is very rare. The authors report an exceptional case of a 20-year-old young woman with intravascular papillary endothelial hyperplasia in the jejunum. The patient was referred to the hospital with a 1-week history of melena. The lesion did not recur after surgery. Histopathological examination revealed a papillary endothelial hyperplasia with an underlying arteriovenous malformation.

              Multiple intravascular papillary endothelial hyperplasia affecting skin and bone.

              We report a 75-year-old man with multiple recurrent black papules involving his entire body. In the course of 3 years, 20 lesions were resected, which were histologically confirmed as intravascular papillary endothelial hyperplasia (IPEH). A similar vascular lesion was found on his tibia. The occurrence of multiple IPEH affecting skin and bone is extremely rare. The patient's medical history included hepatitis C, hepatoma and associated coagulopathy. We suggest that this patient's multiple lesions were induced by microthrombus formation due to liver dysfunction.
