Resumo
O presente estudo teve como objetivo contribuir para a literatura com um caso desafiador de uma lesão assintomática apresentando um aspecto radiolúcido, simulando um cisto residual. Uma mulher de 60 anos apresentou uma lesão na mandíbula, detectada incidentalmente durante exames de imagem. A Tomografia Computadorizada revelou uma lesão hipodensa com margem esclerótica medindo cerca de 0,8 x 0,8 x 0,7 cm na região posterior direita da mandíbula. O principal diagnóstico diferencial foi um cisto residual, e uma biópsia excisional foi realizada. A análise microscópica revelou projeções papilares e trombos no lúmen do vaso revestido por endotélio. A análise imuno-histoquímica foi positiva para CD34 e actina de músculo liso. Com base nesses achados, a lesão foi identificada como hiperplasia endotelial papilar intravascular intraóssea. Este relato de caso fornece informações sobre essa potencial hipótese de radiolucência unilocular localizada nos ossos gnáticos.
