Resumo: We report a case of a pleomorphic xantoastrocytoma which manifested itself as a cystic isodense lesion in the right fronto-temporal lobe in a 26 year-old woman. It appeared as a soft yellow tumor with cystic cavities on surgery. Five months after this surgery, the patient was submitted to a new operation, which revealed a friable tumor, easily differentiated from the normal parenchyma, with cystic components. The histopathological examination demonstrated pleomorphic xanthoastrocytoma with malignant transformation. Histologically, the tumor at first procedure was composed of pleomorphic astrocytes with multinucleated and foamy cells. A rare case of malignant transformation in pleomorphic xanthoastrocytoma is presented, discussed and illustrated in this paper.

Descrevemos um caso de xantoastrocitoma pleomórfico diagnosticado como lesão isodensa no lobo fronto-temporal direito, em uma paciente de 26 anos. Na cirurgia, encontrou-se tumor mole, de cor amarelada, com cavidade cística. Cinco meses após o procedimento, a paciente foi submetida a nova intervenção que revelou um tumor friável, facilmente diferenciado do parênquima normal, com componentes císticos. O exame histopatológico demonstrou um xantoastrocitoma pleomórfico com transformação maligna. O tumor, no primeiro procedimento, era formado por astrócitos pleomórficos com células vacuolizadas e multinucleadas.Federal University of São Paulo Department of NeurosurgeryFederal University of São Paulo Department of PathologyJundiai Medicine School Neurosurgical DepartmentState University of São Paulo Neurosurgical DepartmentUNIFESP, Department of NeurosurgeryUNIFESP, Department of PathologySciELOAcademia Brasileira de Neurologia - ABNEUROUniversidade Federal de São Paulo (UNIFESP)Jundiai Medicine School Neurosurgical DepartmentState University of São Paulo Neurosurgical DepartmentTella Junior, Oswaldo Ignácio de [UNIFESP]Herculano, Marco AntonioPrandini, Mirto Nelso [UNIFESP]Stávale, João Norberto [UNIFESP]Aguiar, Paulo Henrique2015-06-14T13:29:58Z2015-06-14T13:29:58Z2003-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion104-106application/pdfhttp://dx.doi.org/10.1590/S0004-282X2003000100020Arquivos de Neuro-Psiquiatria.
