Sarcoma retroperitoneal: relato de caso

Abstract

Introduction: Retroperitoneal sarcoma is a rare malignant tumor, originating in the mesenchymal cell that undergoes changes in its genetic code, thus producing atypical tissue. It is usually an asymptomatic pathology until it reaches a considerable size of mass, in which, its growth is the main factor causing symptoms. Diagnostic confirmation takes place through imaging tests in addition to biopsy and anatomopathological studies. The treatment of choice is surgery, increasing the survival of the affected patient. Objective: disclose a case of retroperitoneal sarcoma in a patient of the Hospital Escola de Valença, with its consequent outcome, through the analysis of medical records and studies in literature. Case report: 65-years-old man treated at the Hospital Escola de Valença presenting low back pain and hematuria, a retroperitoneal mass was identified with consequent resection and histological studies, showing high degree spindle cell sarcoma. Conclusion: Retroperitoneal lesions are rare findings and represent a therapeutic challenge because, in most cases, patients are asymptomatic or with non specific symptoms.
