ABSTRACT

O caso em questão é o de uma paciente do sexo feminino que apresentava queixa de dor na região anterior do joelho esquerdo durante e após atividades esportivas, seguidas de bloqueio articular havia três meses. Exames de imagem: radiografias simples do joelho normais e ressonância magnética mostrando formação expansiva sólida podendo corresponder a condroma de partes moles ou a sinovite nodular focal. Realizada ressecção artroscópica da lesão com diagnóstico de tumor de células gigantes difuso símile/sinovite vilonodular pigmentada localizada (SVNPL) após resultado do exame anatomopatológico. A paciente apresenta boa evolução clínica com desaparecimento dos sintomas e retorno às atividades físicas.


This case concerned a female patient with a complaint of pain in the anterior region of her left knee during and after sports activities, followed by joint blockage three months ago. From imaging examinations, simple radiography of the knee was normal and magnetic resonance showed a solid expansive mass, possibly corresponding to soft-tissue chondroma or focal nodular synovitis. Arthroscopic resection of the lesion was performed, and the diagnosis of diffuse giant cell tumor resembling localized pigmented villonodular synovitis (PVNS) was made from the result of the anatomopathological examination. The patient presented good clinical evolution, with disappearance of symptoms and return to physical activities.
