Liu W, Yan Y, Wu X, Hou X, Qu X. Myxofibrosarcoma involving brachial plexus diagnoses by contrast-enhanced ultrasound: A case report. Medicine (Baltimore) 2023; 102:e36626. [PMID: 38115261 PMCID: PMC10727635 DOI: 10.1097/md.0000000000036626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 11/22/2023] [Indexed: 12/21/2023] Open
Abstract
RATIONALE Myxofibrosarcoma most commonly arises as a slowly enlarging, painless mass. We describe an unusual case of low-grade myxofibrosarcoma in the axillary fossa, which infiltrated the brachial plexus, axillary artery, and axillary vein, causing severe pain. The low incidence and complex anatomical structure make imaging examination and surgery face great challenges. To the best of our knowledge, such presentation of a low-grade myxofibrosarcoma that showed an extreme infiltrative growth pattern and presented severe pain has not been reported before. PATIENT CONCERNS We reported a case of low-grade myxofibrosarcoma developed around the axillary neurovascular bundle, with multiple peripheral metastases in an 87-year-old male. Physical examination revealed a mass on the right axillary fossa measuring 5 × 4 cm. The patient underwent computed tomography but no definite diagnosis was obtained. Because he had claustrophobia and could not perform MRI examination. Thus, he underwent conventional ultrasound and contrast-enhanced ultrasound. Ultrasonic examination not only accurately determines the invasion scope of the tumor, but also clearly shows that the nerve has suffered from the invasion of the exogenous tumor and multiple metastatic foci around it. The contrast enhancement mode of the tumor showed centripetal high-enhancement, uneven internal enhancement, visible enhanced bridge, and non-enhancing central area. DIAGNOSES Combined with the results of conventional ultrasound and contrast-enhanced ultrasound, we highly suspected it to be soft tissue sarcoma, giving strong clinical assistance. INTERVENTIONS Given the risk of sarcoma implantation along the needle track and the underestimation of tumor malignancy, an excisional biopsy was considered the most practical choice to avoid unnecessary pain and potential implantation. OUTCOMES The patient underwent surgery and a histopathological examination of the lesion confirmed it as low-grade myxofibrosarcoma. LESSONS SUBSECTIONS This report describes a rare case of myxofibrosarcoma of the axillary fossa. High-resolution ultrasound is increasingly used for the initial assessment of soft-tissue masses. However, there are few reports about the ultrasound and contrast-enhanced ultrasound examinations of myxofibrosarcoma. Accurate preoperative diagnosis and proper treatment strategies are critical in managing patients with myxofibrosarcoma. Our case may provide diagnosis experiences and will help better understand and treat this disease.

Abstract
BACKGROUND Myxofibrosarcoma (MFS) is a fibroblast-derived sarcoma that mainly occurs in subcutaneous tissue. MFS rarely occurs in the gastrointestinal tract, especially in the esophagus.
CASE SUMMARY A 79-year-old male patient was admitted to our hospital for dysphagia for a week. Computed tomography and electronic gastroscopy showed that a giant mass was located 30 cm from the incisor and extended to the cardia. There was incomplete esophageal stenosis. Endoscopic pathology showed spindle cell lesions, which were considered inflammatory myofibroblast like hyperplasia. Considering the strong demands of the patient and his family, and the fact that most inflammatory myofibroblast tumors are benign, we decided to perform endoscopic submucosal dissection (ESD) even if the tumor size was giant (9.0 cm × 3.0 cm). Postoperative pathological examination resulted in a final diagnosis of MFS. MFS rarely occurs in the gastrointestinal tract, especially in the esophagus. Surgical resection and local adjuvant radiotherapy are the first choices to improve the prognosis. This case report firstly described the ESD for esophageal giant MFS. It suggests that ESD may be an alternative treatment for primary esophageal MFS.
CONCLUSION This case report for the first time describe the successful treatment of a giant esophageal MFS by ESD, suggesting that ESD may be an alternative treatment for primary esophageal MFS, especially in elderly high-risk patients with obvious dysphagia symptoms.

[PMID: 35256287 PMCID: PMC9801034 DOI: 10.1016/j.bjorl.2022.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 01/14/2022] [Accepted: 02/02/2022] [Indexed: 01/03/2023] Open
Abstract
OBJECTIVE The aim of this study was to report 6 cases of sinonasal/basicranial myxofibrosarcoma and review demographic data, clinical symptoms, diagnostic methods, therapeutic methods, and prognosis on this subject in the literature. METHODS We conducted a retrospective analysis of six patients referred to our hospital during a 10-year period from 2010 to 2020. RESULTS In this series, there were four males and two females. The tumours originated from the maxillary sinus in all six cases. The symptoms were nonspecific, and all patients underwent endoscopic resection alone or combined with open resection. The postoperative period was uneventful. All patients were diagnosed with myxofibrosarcoma. After a median follow-up period of 36 (6-52) months, the recurrence rate of MFS was 66.7% (4/6), and the mortality rate was 50% (3/6). CONCLUSION Sinonasal/basicranial MFS is a rare neoplasm, and the most common primary site is the maxillary sinus. When diagnosing MFS, osteolysis may help rule out benign lesions. So far surgery is the mainstay of treatment for sinonasal/basicranial MFS. Our surgical strategy using endoscopic resection or endoscopic resection combined with open resection to achieve a negative surgical margin and using re-excision operations to treat relapsed cases may be recommended to rhinologists who treat MFS. Prospective randomised trials are needed to study the role of chemotherapy, radiotherapy, and our surgical strategy for sinonasal/basicranial MFS. Diagnosing patients at an earlier stage and better patient compliance with follow-up plans may improve the prognosis of patients.

Abstract
BACKGROUND Myxofibrosarcoma (MFS), especially radiation-Induced MFS (RIMFS) in the head and neck, is an extremely rare malignant fibroblastic tumor. The diagnosis and treatment of MFS remain great challenges. In the present study, we presented one case of RIMFS. Combined with previous literature, the clinical features, essentials of diagnosis, and treatment modalities of MFS in the head and neck were reviewed to better understand this rare entity. CASE PRESENTATION We reported a case of RIMFS under the left occipital scalp in a 20-year-old girl with a history of medulloblastoma surgery and radiotherapy in 2006. A total tumor resection was performed with preservation of the overlying scalp the underlying bone, and no adjuvant therapy was administered after the first operation. The postoperative pathological diagnosis was high-grade MFS. The tumor relapsed 6 months later, and then, a planned extensive resection with negative surgical margins was carried out, followed by radiotherapy. No relapse occurred in a 12-month postoperative follow-up. CONCLUSIONS Planned gross total resection (GTR) with negative margins is the reasonable choice and footstone of other treatments for MFS. Ill-defined infiltrated borders and the complicated structures make it a great trouble to achieve total resection of MFS in the head and neck, so adjuvant radiotherapy and chemotherapy seem more necessary for these lesions.

Abstract
Myxofibrosarcoma is a malignant pleomorphic fibroblastic sarcoma with variably myxoid stroma, and is characterised by a distinctive curvilinear vascular pattern. In the head and neck area, myxofibrosarcoma is extremely rare, with only a handful of case reports in the literature to date. We report the first case series of primary sinonasal myxofibrosarcoma across two institutions. Among the five cases (2 female, 3 males, aged 52-82 years old), four arose from the maxillary sinus and one from the sphenoid sinus. Four patients received surgical resection and three with adjuvant radiotherapy. The tumours ranged from 2.9 to 5.6 cm in greatest dimensions. All tumours demonstrated extensive myxoid stroma (>50% myxoid component) with a characteristic curvilinear, elongated, thin-walled vasculature with perivascular condensation of tumour cells. All but one were classified as intermediate to high grade myxofibrosarcoma. Among the four patients with follow-up information, three reported no local recurrence or distal metastasis, and one had local recurrence. Myxofibrosarcoma should be included in the differential diagnosis of sinonasal tumours with a pleomorphic spindle cell morphology and a 'null' immunophenotype.

Abstract
BACKGROUND A myxofibrosarcoma (MFS) is a malignant fibroblastic tumor that tends to occur in the lower and upper extremities. The reported incidence of head and neck MFSs is extremely rare. We report a 46-year-old male with “a neoplasm in the scalp” who was hospitalized and diagnosed with an MFS (highly malignant with massive necrotic lesions) based on histologic and immunohistochemistry evaluations. The magnetic resonance imaging manifestations did not demonstrate the “tail sign” mentioned in several studies, which resulted in a great challenge to establish an imaging diagnosis. The treatment plan is closely associated with the anatomic location and histologic grade, and more importantly, aggressive surgery and adjuvant radiotherapy may be helpful. Hence, we report the case and share some valuable information about the disease.
CASE SUMMARY A 46-year-old male with “a neoplasm in the scalp for 6 mo” was hospitalized. Initially, the tumor was about the size of a soybean, without algesia or ulceration. The patient ignored the growth, did not seek treatment, and thus, did not receive treatment. Recently, the tumor increased to the size of an egg; there was no bleeding or algesia. His family history was unremarkable. No abnormalities were found upon laboratory testing, including routine hematologic, biochemistry, and tumor markers. Computed tomography showed an ovoid mass (6.25 cm × 3.29 cm × 3.09 cm in size) in the left frontal scalp with low density intermingled with equidense strips in adjacent areas of the scalp. Magnetic resonance imaging revealed a lesion with an irregular surface and an approximate size of 3.55 cm × 6.34 cm in the left frontal region, with clear boundaries and visible separation. Adjacent areas of the skull were damaged and the dura mater was involved. Contrast enhancement showed an uneven enhancement pattern. Surgery was performed and postoperative adjuvant radiotherapy was administered to avoid recurrence or metastasis. The post-operative pathologic diagnosis confirmed an MFS. A repeat computed tomography scan showed no local recurrence or distant metastasis 19 mo post-operatively.
CONCLUSION The case reported herein of MFS was demonstrated in an extremely rare location on the scalp and had atypical magnetic resonance imaging findings, which serves as a reminder to radiologists of the possibility of this diagnosis to assist in clinical treatment. Given the special anatomic location and the high malignant potential of this rare tumor, combined surgical and adjuvant radiotherapy should be considered to avoid local recurrence and distant metastasis. The significance of regular follow-up is strongly recommended to improve the long-term survival rate.

Abstract
Background Myxofibrosarcoma (MFS) is a soft tissue sarcoma that commonly occurs in late adult life. It is mainly located in the subcutaneous soft tissues of extremities characterized by a high recurrence rate at the original site. MFS of the head and neck is rare, while it occurs in the maxilla and mandible is extremely rare. Case presentation We report a case of MFS of the mandible in a 51-year-old female who presented with a painless gingival swelling and mobile, super-erupted right mandibular second and third molars. Panoramic x-ray and maxillofacial CT revealed an ill-defined radiolucent lesion surrounding the mandibular molars giving a teeth-floating-in-air appearance. Histopathological examination showed scattered spindle and stellate cells with mild atypia distributed in the myxoid stroma. Only a few mitotic figures were identified and no area of tissue necrosis was found. The characteristic thin-walled and curvilinear vasculature were prominent. Immunohistochemistry analysis revealed the tumor cells being positive for vimentin and vascular CD31. CK, S-100, P63, HHF-35 stains were negative. The labeling index of Ki-67 was about 30%. Based on the histopathological and immunohistochemical examinations, the diagnosis of a low-grade MFS was established. This patient underwent a radical segmental excision with a 2-cm margin, supraomohyoid neck dissection and immediate reconstruction of the mandibular continuity defect with a fibular osteocutaneous free flap. This patient has been followed for 20 months to date and has remained disease free. Conclusions This report describes a rare case of MFS of the mandible. Recognizing the histopathological features of MFS and applying the appropriate immunohistochemical examinations are crucial in establishing the correct diagnosis. Our case may provide diagnosis and treatment experiences of MFS occurs in the mandible.

Abstract
BACKGROUND Myxofibrosarcoma (MFS) is most often found on the limbs of aged male people, but extremely uncommon in the liver. CASE PRESENTATION A 52-year-old female patient with a liver mass was diagnosed as a primary MFS. It had no obvious abdominal symptoms, and the tumor was resected with an extended margin. Three years after the surgery, the patient was readmitted for peritoneal metastasis and passed away 4 months later. The tumor has a benign presentation, but malignant outcome. CONCLUSIONS Comprehensive radiological inspection, intensive preoperative evaluation, careful design of operating procedures, wide margin resection, consecutive treatment, and strict periodical follow-ups should be taken to ensure a better prognosis of this kind of neoplastic disease.

Abstract
Myxofibrosarcoma (MFS) is a malignant fibroblastic tumor that primarily affects the lower and upper extremities. It is usually described as a slow-growing tumor with high recurrence rates but low metastatic potential. The reported incidence of head and neck MFS is 2 to 4% and rarely presents with distant metastases. This report describes a case of maxillary MFS in a 72-year-old woman whose disease progression followed an atypical course with an extremely rapid rate of growth and early pulmonary and central nervous system lesions. The pulmonary symptoms at initial presentation made a final diagnosis a challenge. Various diagnostic modalities and multidisciplinary collaboration were required. The disease course and management are outlined. To the authors' knowledge, this is the first case of MFS originating in the maxillary alveolus with multiple metastases, including the brain and lungs, in the early course of the disease.

Abstract
Myxofibrosarcoma is a common sarcoma in the extremities of older people, but is rare in the head and neck region. Here, we report the case of a 42-year-old male patient in whom myxofibrosarcoma generated from the sinus piriformis. Histopathologically, the tumor was characterized by spindle cellular proliferation with moderate cellular density in fibromyxoid stroma. Immunohistochemically, the tumor cells showed positive reactivity for vimentin, Ki-67, smooth muscle actin, and CD34, but negative staining for S-100. Based on these results, the tumor was diagnosed as a low-grade myxofibrosarcoma. Resection of the tumor was performed via a transcervical approach. The patient’s postoperative clinical course was uneventful and no local recurrence or distant metastasis has been found so far. The pathology, clinical characteristics, and treatment of myxofibrosarcoma are also reviewed.
