Recurring facial low-grade fibromyxoid sarcoma in an elderly patient: a case report.

Low-grade fibromyxoid sarcoma (LGFMS) is a rare type of sarcoma that is characterized by benign-appearing histologic features but a paradoxically aggressive clinical course. These tumors generally occur in young to middle-aged adults, sometimes in children, but rarely in high-aged adults. LGFMS typically affects the deep soft tissues of the trunk or lower extremities; however, it is rarely seen in the face. We here describe a case of LGFMS on the right forehead of an 84-year-old woman. After resection with a 1-cm skin margin, recurrence occurred at 15 months postoperatively. Additional wide excision was subsequently performed with a 2-cm skin margin. Recurrence and metastasis have not been observed for 1 year after the second excision. A wide surgical margin should be considered in cases of LGFMS.
