Postoperative recurrence of myxoid liposarcoma of left thigh with pericardial metastasis: A case report

Myxoid liposarcoma (MLS) is a common subtype of liposarcoma in children and adolescents and can occur anywhere in the body. Cardiac metastases from MLS are very rare. We report a rare case of postoperative recurrence of MLS in the left thigh with ectopic and metachronous pericardial metastases. Cardiac metastases from MLS are rare, the prognosis is poor, and long-term follow-up of patients after discharge is necessary.
