RESUMO
Intravascular papillary endothelial hyperplasia (IPEH) is characterized by proliferation of endothelial cells usually occurring within a long-standing vascular malformation or tumor. IPEH usually affects neck, head and lower extremities, and few orbital and eyelid cases have been reported. We present a unique case, a 48-years-old man with a purple, elevated, multilobular conjunctival lesion of three-weeks duration that underwent an excisional biopsy. Pathological features revealed intravascular papillary endothelial hyperplasia (Masson's tumor).

La hiperplasia endotelial papilar intravascular (IPEH) se caracteriza por la proliferación de células endoteliales generalmente producida dentro de una malformación vascular previa o un tumor. La IPEH suele afectar cuello, cabeza y extremidades inferiores, se han publicado pocos casos en la órbita ocular y párpados. Presentamos un caso único, un hombre de 48 años con una lesión conjuntival púrpura, elevada y multilobular de tres semanas de duración que se sometió a una biopsia excisional. Las características patológicas revelaron una hiperplasia endotelial papilar intravascular (tumor de Masson) (AU)
