Tumor maligno de bainha do nervo periférico: Relato de caso raro de sarcoma primário do coração

Primary malignant tumors of the heart are rare diseases, with sarcomas being the most common. The present study reports the case of a rare malignant tumor of the peripheral nerve sheath with cardiac involvement. This is an observational, descriptive, and retrospective study. The case describes the clinical presentation of nonspecific respiratory symptoms in a patient, with rapid progression and functional impairment, in which multiple clinical, laboratory, and imaging examinations were required to determine the etiology of the condition; however, surgical resection and anatomopathological examination were ultimately necessary to establish the final diagnosis and improve the symptoms presented.
