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...

There are limited data regarding the molecular characterization of undifferentiated pleomorphic sarcomas (UPS; formerly malignant fibrous histiocytoma). This study aimed to investigate the utility of next generation sequencing (NGS) in UPS to identify subsets of patients who harbour actionable mutations. Patients diagnosed with UPS underwent pathological re-evaluation by a pathologist specializing in sarcoma. Tumor DNA was isolated from archived fresh frozen tissue samples and genotyped using NGS with the Illumina MiSeq TruSeq Amplicon Cancer Panel (48 genes, 212 amplicons)...

BACKGROUND: Tumor embolisms (TE) are an underappreciated source of pulmonary embolisms in sarcoma. Most evidence in the literature is limited to case reports and none have described the presence of TE secondary to myxofibrosarcoma. We report the first case of myxofibrosarcoma TE and perform a review of the literature for TE secondary to bone and soft tissue sarcomas (STS). CASE PRESENTATION: A 36-year-old female presented with debilitating pain of the right upper extremity secondary to a recurrent soft tissue sarcoma...

OBJECTIVE: Programmed death ligand 1 (PD-L1) found on tumor cells has recently been reported to have a key role in the development and dissemination of many tumors, such as lung and breast carcinomas. In this study, we retrospectively analyzed PD-L1 expression among different types of sarcomas. MATERIAL AND METHOD: Tissue microarrays of 3-4 mm diameter were composed from paraffin blocks of 222 various sarcomas. Slides prepared from microarrays were stained for PD-L1 antibody (Cell Signaling, E1L3N®) using Leica Bond Autostainer...

PURPOSE: A clinical feature of myxofibrosarcoma is local recurrence, but knowledge about distant metastasis is sparse. We evaluated the tendency of clinical and histological features of metastasis in myxofibrosarcoma patients. METHODS: Fifty-eight patients with myxofibrosarcoma were treated in our hospitals, and a total of 16 consecutive patients with distant metastases were included in this retrospective study (9 males and 7 females, with a mean age of 77 years)...

Myxofibrosarcomas are morphologically heterogeneous soft tissue sarcomas lacking a specific immunohistochemical expression profile and recurrent genetic changes. The study was designed to gain further insights into the molecular landscape of myxofibrosarcomas by targeted re-sequencing of known cancer driver hotspot mutations and the analysis of genomewide somatic copy number alterations. A well-defined group of myxofibrosarcomas, including myxofibrosarcomas G1 (n=6), myxofibrosarcomas G3 (n=7), myxofibrosarcomas with morphologically heterogeneous and independently selectable G1 and G3 areas within a tumor (n=8), and myxofibrosarcomas G3 with subsequent tumor recurrence (n=1) or metastatic disease (n=3) were evaluated...

Synovial sarcoma is a high-grade sarcoma commonly affecting young adults. The sites of involvement include soft tissue near joints, lung, pleura, mediastinum, larynx, kidney, and buttocks. Histologic types include monophasic, biphasic, and undifferentiated. We report a unique case of synovial sarcoma with low-grade histologic features mimicking pleomorphic hyalinizing angiectatic tumor (PHAT) with indolent behavior for a period of 10 years. The tumor showed angiectatic blood vessels with fibrinous cuffing, hypocellular and hypercellular spindle cell areas with rare mitoses, and focal atypia in a myxoid background...

We present the particular clinical and histological features of a metastatic high-grade myxofibrosarcoma (MFS) of the left buttock in a 77-year-old male patient. The tumor was biopsied and surgically removed in order to increase the patient's comfort, due to its increased size and aggressive clinical behavior. Computed tomography (CT) revealed metastases in the pleura and mediastinal lymph nodes, so limb-sparing tumor excision followed by palliative care was the best practice for the patient until the fatal outcome...

Myxofibrosarcoma (MFS) is a mesenchymal malignancy characterized by frequent recurrence even after radical wide resection. To optimize therapy for MFS patients, we aimed to identify candidate tissue biomarkers of MFS invasion potential. Invasion characteristics of MFS were evaluated by magnetic resonance imaging and protein expression profiling of primary tumor tissues performed using two-dimensional difference gel electrophoresis (2D-DIGE). Protein expression profiles were compared between invasive and non-invasive tumors surgically resected from 11 patients...

BACKGROUND: Myxofibrosarcoma (MFS) is a common sarcoma in the extremities of older individuals but is extremely uncommon in the head and neck region. Diagnosis may be challenging but is critical to the management of the patient. We discuss the radiographic and histopathologic characteristics of this destructive tumor. The distinguishing features of MFS and its differential diagnosis are reviewed to familiarize the managing otolaryngologist with this rare entity. METHODS: A 61-year-old woman presents with a 6-week history of severe left facial pain and left eye pain...

The authors present a case of a 57-year-old man, who presented to the surgical clinic with a mass in the suprapubic region. A CT scan revealed a well-circumscribed lobular, heterogeneous soft tissue mass measuring 12×8.6×7.8 cm. The final histopathological diagnosis from the resection of the lesion was a myxofibrosarcoma (MFS), grade 3. The management of MFS includes surgical and oncological options which are reviewed here. These are aimed at complete excision and reducing the risk of local occurrence.

OBJECTIVE: Osteosarcoma (OS) is a commonly diagnosed bone malignancy in children and adolescents. Nuclear division cycle 80 (NDC80) is a crucial regulator of the cell division cycle that has recently been identified as a novel oncoprotein in various solid tumors; however, its role in OS remains poorly understood. The aim of this study was to investigate correlations between NDC80 expression in OS patients and clinicopathological features and prognosis. PATIENTS AND METHODS: We began this study by determining NDC80 expression in sarcoma patients using the Oncomine Platform...

Nuclear medicine labeled leukocyte whole-body scintigraphy is commonly used to identify a source of infection in a patient with fever of unknown origin. White blood cells can also localize to other sites of inflammation, including sometimes tumors. A patient with a large myxofibrosarcoma in his left forearm was scanned due to chronic low-grade fever and persistent leukocytosis. This case demonstrates focal white blood cell activity in an extremity soft tissue sarcoma.

Myxofibrosarcoma (MFS) is characterized by abundant myxoid stroma, a wide spectrum of cytological atypia, and frequent local recurrence. Some soft tissue tumors with myxoid stroma can histologically mimic MFS, but have different biological behaviors. Here we sought to identify a useful diagnostic marker for MFS. After our analysis of the gene expression dataset from the Gene Expression Omnibus database, we focused on claudin 6 (CLDN 6). The status of CLDN 6 was assessed by immunohistochemistry in 61 samples of MFS and other (benign) myxoid soft tissue tumors (28 myxoma samples, 12 nodular fasciitis samples), 18 low-grade fibromyxoid sarcoma, 30 myxoid liposarcoma, 29 extraskeletal myxoid chondrosarcoma and 27 dedifferentiated liposarcoma with myxoid feature samples...

Approximately 3300 new primary bone tumors will present to American physicians this year. This small but important group of malignancies has become more defined with developments in pathologic morphology, immunohistochemistry, and molecular studies. As tumor types are better partitioned, their specific characteristics are more readily observed. In this article we present the first reported case of a myxofibrosarcoma of bone developing within a bone infarct. With improved delineation of rarer tumor types, it is expected that additional cases of myxofibrosarcoma of bone will be recognized, potentially arising from a bone infarct...

Soft-tissue sarcomas (STS) are rare malignancies that account for 1% of adult cancers and comprise more than 50 entities. Current therapeutic options for advanced-stage STS are limited. Immune checkpoint inhibitors targeting the PD-1/PD-L1 signaling axis are being explored as new treatment modality in STS; however, the determinants of response to these agents are largely unknown. Using the sarcoma data set of The Cancer Genome Altas (TCGA) and an independent cohort of untreated high-grade STS, we analyzed DNA copy number status and mRNA expression of PD-L1 in a total of 335 STS cases...
