Local Recurrence of Primary Cardiac Leiomyosarcoma After Resection: A Rare Case

Abstract

Introduction: Leiomyosarcoma (LMS) is a fatal tumor, though primary cardiac is very rarely encountered. In this report, we evaluated the surgical and medical management of primary cardiac LMS, which is a sporadic tumor. Case Presentation: A 60-year-old female patient was examined for pulmonary edema after penicillin allergy in May 2019, while transthoracic echocardiography (ECHO) revealed an appearance compatible with a 5x3.5 cm mass in the right atrium. In addition, transesophageal ECHO showed a 7x4.6 cm foreground mass compatible with a myxoma in the right atrium (RA). The patient was then operated on emergency. Besides, an adjuvant ifosfamide-mesna-doxorubicine (IMA) protocol was planned to be given to the patient after local radiotherapy. Conclusions: In this report presented, we made RT and chemotherapy treatment plans in the case of recurrence without R0 surgery. Recurrence rates of up to 50% can occur in LMS, and systemic chemotherapy can be applied after relapse
