Abstract

Introduction: Myxofibrosarcoma (MFS) is a type of malignancy from the group of malignant fibrous histiocytoma. Myfxofibrosarcoma is a type of soft tissue neoplasm that is aggressive. The clinical symptoms are not pathognomonic and the histological picture is very heterogeneous, often receiving delayed treatment and causing misdiagnosis. Complementary histochemical and immunohistochemical staining is mandatory to confirm the diagnosis of MFS. Extensive surgical treatment and followed by radiotherapy is the first choice of myxofibrosarcoma treatment.

Case Presentation: A 54-years old woman complained of a lump on her left thigh that had been getting bigger for the past 2 years. The lump initially looked the size of a marble, then grew to the size of a tennis ball in the last 7 months. On physical examination, a mass was found in the left thigh area, a hard, fixed mass, the size of a tennis ball. Fine needle aspiration examination showed suspicious results for myxofibrosarcoma. The patient underwent a Magnetic Resonance Imaging examination in the left lower extremity area and underwent wide excision and anterior thigh compartment resection surgery.

Discussion: Wide resection is the standard treatment for MFS [4]. The choice of procedure for each patient is different and should be based on tumor size, location, stage, surrounding neurovascular and bony elements, as well as functional and cosmetic considerations [4]. The minimum resection margin in MFS is at least 1 cm which aims to minimize the risk of local recurrence [4]. The recommended resection margin is at least 2 cm for MFS resection [4]. We had plan a 2 cm margin of the entire preoperative MRI enhancement area. It should be noted that the local recurrence rate for MFS in margin-negative resections is relatively high compared with other STS subtypes.

Conclusion: We recommend Wide Excison and Modified Anterior Thigh compartment Resection is recommended procedure for anterior thigh myxofibrosarcoma. This procedure involves preserving uncontaminated thigh neurovascular, and only resecting one of the sarcoma-infiltrated muscle heads and preserving the other quadriceps muscle head of the thigh to maintain knee extension function. This paper is the first report on the successful treatment of anterior thigh myxofibrosarcoma without weakness of knee extension complication.
