Primary bone sarcomas represent extremely rare entities. The use of now abolished labels, such as malignant fibrous histiocytoma and hemangiopericytoma, has significantly hampered the chance of identifying specific entities. It is now accepted that a broad variety of mesenchymal malignancies most often arising on the soft tissue may actually present as primary bone lesions. A more accurate morphologic partition is justified based on availability of distinct therapeutic options. An integrated diagnostic approach represents the only way to achieve a correct classification...

Malignant fibrous histiocytoma (MFH) represents a rare malignant affection of heart and aorta. Its clinical presentation depends on the localisation, size, degree of invasion and metastasis. Previously, relatively few cases of acute tumour mass embolisation into the visceral and limb arterial system were described in the literature. In the present case study we describe a case of acute ischemia of both lower extremities caused by thromboembolic mass of MFH cells. According to literary sources this tumour type is characterized by poor prognosis as it was in the case of our patient...

Objective: To investigate the operative method and clinical application of the BARD(®) Mesh in enhancing joint stability and function of endoprosthetic reconstruction for bone tumors. Methods: From Jan 2013 to Jun 2015, the clinical data of 51 patients aged (44.75±23.18) years underwent wide resection of tumor and endoprosthetic reconstruction using the BARD(®) Mesh were collected. Among them, 27 were male and 24 were female. The surgical treatments received by these patients included 5 shoulder arthroplasties, 12 elbow replacements, 12 hip replacements and 32 knee replacements (including 24 femoral tumors and 8 tibial tumors)...

Although fibrous dysplasia is not considered a potentially premalignant disorder, malignant transformation occurs. Because of its rarity, radiographic features of malignantly transformed fibrous dysplasia on cross-sectional imaging modalities are less recognized, making diagnosis and differential diagnosis of the disease quite difficult in clinical practice. In this study, we analyzed the clinical characteristics, imaging features, pathology findings and surgery strategies of 19 malignantly transformed fibrous dysplasia...

Osteochondroma is the most common benign bone tumor. Approximately 15% of osteochondromas occur as multiple lesions. Multiple osteochondromatosis has a higher risk of developing chondrosarcomas, which are of low grade with good prognosis. About 10% of all chondrosarcomas may undergo dedifferentiated change, which has a poorer prognosis. Dedifferentiated peripheral chondrosarcoma developing within an osteochondroma is extremely rare. Dedifferentiation usually occurs in the form of osteosarcoma, malignant fibrous histiocytoma, fibrosarcoma, or rhabdomyosarcoma...

Pleomorphic undifferentiated sarcoma (PUS), also called malignant fibrous histiocytoma, is a soft tissue sarcoma which occurs predominantly in the extremities. Its origin is a poorly defined mesenchymal cell, which derives to histiocytic and fibroblastic cells. The patient, a 58 year-old man, presented a lesion located in the forearm composed by spindle cells and multinucleated giant cells, which expressed vimentin and adopted a histological pattern formed by irregular-swirling fascicles. Cells were cultured in vitro and a new cell line was established...

Dedifferentiated chondrosarcomas (DDCS) are rare lesions, defined as tumors having a low-grade chondrosarcomatous component with an abrupt transition to a high-grade sarcoma. Although "malignant fibrous histiocytoma" (undifferentiated pleomorphic sarcoma) is the most common high grade saromatous component, many different types of sarcoma have been described. We present a case of dedifferentiated chondrosarcoma with rhabdomyosarcomatous differentiation harboring a prominent rhabdoid tumor component. To our knowledge, rhabdoid morphology in dedifferentiated chondrosarcoma has not been described in the English-language literature...

INTRODUCTION: Osteosarcoma is a malignant mesenchymal tumor whose cancerous cells produce osteoid matrix. It is a common primary malignant bone tumor, representing 23% of total head and neck malignancies. Osteosarcomas of the jaws are rare lesions, representing only 4-7% of all osteosarcomas. This presentation discusses the clinical, radiographical, and histopathological features of a case of osteosarcoma of the mandible with unusual histopathological appearance. CASE REPORT: A 21-year-old male patient reported with a diffuse swelling of the right side of mandible with dull ache and increasing difficulties with eating and speech...

TLR4, an important Toll-like receptor in innate immunity, can be activated by LPS and induce proinflammatory cytokines to resist invasion of pathogenic microorganism, but excessive inflammation can trigger tissue injury. Many genes negatively regulate TLR4 signaling pathway. Recent studies found that malignant fibrous histiocytoma amplified sequence 1 (MFHAS1) suppressed the expression of cytokine IL6 in Raw264.7 cells stimulated by LPS, but the mechanisms remained unclear. This study investigated the role of MFHAS1 in TLR4 signaling pathway and the possible mechanisms implicated...

RATIONALE: Malignant fibrous histiocytoma (MFH), primary presented in liver, was very rare and displayed a poor prognosis because of high aggression. As a few of cases had been reported merely, we shared the case of primary hepatic MFH combined with invasion of inferior vena cava (IVC). PATIENTS CONCERNS: A 69-year-old women presented with abdominal pain. DIAGNOSES: Abdominal computed tomography and magnetic resonance imaging indicated a soft mass about 5...

BACKGROUND: Soft-tissue sarcoma (STS) rarely metastasizes to lymph node compared to carcinoma. Fine-needle aspiration cytology (FNAC) carries a pivotal role in diagnosis of metastatic tumor to lymph node. This study highlights the role of FNAC in diagnosis of STS metastasis to lymph node. METHOD: A retrospective study over a period by 4 years carried out. FNAC of enlarged lymph node was performed in patients with STS. Cytology smears were examined in conjunction with clinical details...

BACKGROUND: Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue neoplasm, and its rarity makes studying it difficult. We found that several of our patients with AFH presented with radiologically suspicious local lymph nodes that were sampled because of their imaging characteristics, but the nodes proved to be benign on pathologic evaluation. Although the frequency of this finding is unknown, it seems important for orthopaedic oncologists who care for patients with AFH to know whether suspicious-appearing associated nodes in these patients warrant aggressive management...

BACKGROUND: Sarcomas affecting the head and neck often require complex management due to the combination of anatomic, aesthetic and oncological considerations. The incidence and patterns of presentation are poorly understood and have not been reviewed in the Australian population. METHOD: This study sourced incidence and demographic data from the National Cancer Registry at the Australian Institute of Health and Welfare for the years 1982-2009 (corresponding to 97...

The following report describes the case of a 43-year-old male smoker that was referred to the rapid access lung clinic with haemoptysis, chest pain, and axillary lymphadenopathy-a clinical picture that raised concern for a possible underlying malignancy. Preliminary investigations revealed elevated D-dimers, low-volume haemoptysis, and a normal chest X-ray, which lowered the index of suspicion. However, computed tomography (CT) pulmonary angiogram identified a right hilar mass, several parenchymal cysts, and a large mediastinal mass...

Soft-tissue sarcomas occurring in the abdomen and pelvis are an uncommon but important group of malignancies. Recent changes to the World Health Organization classification of soft-tissue tumors include the movement of gastrointestinal stromal tumors (GISTs) into the soft-tissue tumor classification. GIST is the most common intraperitoneal sarcoma. Liposarcoma is the most common retroperitoneal sarcoma, and leiomyosarcoma is the second most common. GIST, liposarcoma, and leiomyosarcoma account for the majority of sarcomas encountered in the abdomen and pelvis and are discussed in part 1 of this article...

A male child, born from consanguineous parents and having intellectual disability, short stature, dysmorphic facial features, synpolydactyly, and cardiac malformations is reported. Chromosomal microarray analysis showed that the patient presents with an 8p23.1 homozygous deletion, containing the microRNA miR-4660, the exoribonuclease 1 (ERI1), and malignant fibrous histiocytoma amplified sequence 1 (MFHAS1) genes. The microRNA miR-4660 has no known function. MFHAS1 is an immunomodulatory protein involved in Toll-like receptor signaling, erythropoiesis, and cancer...

Sepsis is a systemic inflammation caused by infection. The balance between M1-M2 macrophage polarization has an essential role in the pathogenesis of sepsis. However, the exact mechanism underlying macrophage polarization is unclear. We previously showed that levels of malignant fibrous histiocytoma amplified sequence 1 (MFHAS1) were significantly elevated in septic patients compared with those in nonseptic patients, and involved in the activation of Toll-like receptor (TLR) 2/c-Jun N-terminal kinase (JNK)/nuclear factor (NF)-κB pathway...

Malignant fibrous histiocytoma is a sarcoma with rare occurrence in the oral and maxillofacial region; surgery is the most reliable treatment. Inadequate resection of the sarcoma on the oral and maxillofacial region is associated with a high incidence of local recurrence and a poor prognosis. Only few patients of malignant fibrous histiocytoma of the malar region have been previously reported in the literature. The authors report a new patient of malignant fibrous histiocytoma on the right malar region that treated a complete tumor surgical excision without lymph node dissection...
