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...

Carbon dioxide (CO2) therapy can be applied to treat a variety of disorders. We previously found that transcutaneous application of CO2 with a hydrogel decreased the tumor volume of several types of tumors and induced apoptosis via the mitochondrial pathway. However, only one condition of treatment intensity has been tested. For widespread application in clinical antitumor therapy, the conditions must be optimized. In the present study, we investigated the relationship between the duration, frequency, and treatment interval of transcutaneous CO2 application and antitumor effects in murine xenograft models...

Tumor metastasis to lymph nodes is an important contributory factor for cancer-related deaths despite recent developments in cancer therapy. In this study, we demonstrate that tumor in the proper axillary lymph node (PALN) of the mouse can be treated by the application of external laser light to trigger the unloading of doxorubicin (DOX) encapsulated in thermosensitive liposomes (TSLs) administered together with gold nanorods (GNRs). GNRs + DOX-TSLs were injected into a mouse lymph node containing cancer cells (malignant fibrous histiocytoma-like cells) and intranodal DOX release was activated using near-infrared (NIR) laser irradiation...

A 68-year-old gentleman presented with a lesion that resembled a pyogenic granuloma in his inferior fornix. The lesion was excised and biopsy demonstrated a proliferation of malignant spindle cells. Three weeks following initial excision, the lesion recurred and was removed via wedge excision of the eyelid. Definitive clearance was achieved through Mohs micrographic surgery. The patient received adjuvant postoperative radiotherapy and remains disease-free. This case demonstrates the need to consider sinister pathology in the setting of recurrent periocular lesions...

Primary Malignant Fibrous Histiocytoma (MFH-T) and Leiomyosarcoma (LMS-T) of the thyroid gland are extremely rare tumors. Very few cases have been reported in the literature. Both entities occur more commonly in women than men. The closest clinical and histological differential diagnosis is anaplastic carcinoma of thyroid. We present three cases of rare primary sarcomas of thyroid gland. Case-1 was a 63-year-old woman and Case-2 was a 52-year-old woman. Both of them presented with a rapidly increasing thyroid mass clinically mimicking anaplastic carcinoma (AC-T)...

BACKGROUND: The risk of local recurrence (LR) after soft tissue sarcoma (STS) resection is higher in the setting of inadvertent positive margins (IPMs). This study assessed whether both tumor- and surgery-related factors contribute to IPMs, and whether tumor- versus surgery-related IPMs differ in LR or overall survival (OS). METHODS: Retrospective review of a tertiary center database identified patients with IPMs following STS resection between 1989 and 2014. Of 2234 resected STSs, 309 (13%) had positive margins; 89 (4%) were IPMs...

BACKGROUND: Dedifferentiated chondrosarcoma is a rare, highly malignant tumor with a poor survival. There are many confusing issues concerning the imaging feature that can facilitate early diagnosis and the factors that might be related to outcomes. METHODS: Twenty-three patients with dedifferentiated chondrosarcoma confirmed by pathology were retrospectively reviewed from 2008 to 2015. The patients' clinical information, images from radiographs (n = 17), CT (n = 19), and MRI (n = 17), histological features, treatment and prognosis were analyzed...

BACKGROUND: Myxofibrosarcoma is an aggressive soft tissue neoplasm, classified as a variant of malignant fibrous histiocytoma. Most often, it occurs in middle to late adult life peaking in the seventh decade and involving the lower extremities (77%), trunk (12%), and retroperitoneum or mediastinum (8%). We report the first case of thoracic myxofibrosarcoma presenting as a Pancoast tumor. CASE PRESENTATION: A 48-year-old non-tobacco smoking African-American man presented with a slow-growing mass in his neck along with 11 kg weight loss over 9 months...

Gliosarcoma, a variant of isocitrate dehydrogenase-wildtype glioblastoma, is largely a lobar surfacing neoplasm often with dural attachment. In this biphasic neoplasm, the sarcomatous component usually takes the form of fibrosarcoma or malignant fibrous histiocytoma. Heterologous sarcomatous differentiation is a rare phenomenon. Here, we present a case of gliosarcoma with liposarcomatous and myosarcomatous differentiation in a 68-year-old man which was purely intraventricular. This is the first report of such a morphologic pattern in this location...

OBJECTIVE: Peripheral venous reconstruction surgery may be necessary for appropriate oncologic resection; however, the operative approach and surgical outcomes are not well described. We report our experience with these complex reconstructions to identify best practice. METHODS: We retrospectively reviewed all adult patients who underwent peripheral vein reconstruction for tumor resection at Mayo Clinic, Rochester (2000-2015). Patients were classified into three subgroups by the location: iliac (IL), lower extremity (LE), and upper extremity (UE)...

We present a very rare case of malignant transformation of a benign mature cystic teratoma. The pathology report revealed malignant transformation of both the epithelial and sarcomatous elements of a benign dermoid cyst. To the best of our knowledge, this appears to be the third case of a malignant fibrous histiocytoma and a squamous cell carcinoma developing from a mature cystic teratoma. Malignant transformation of a dermoid cyst is usually diagnosed postmenopausally, but our patient was premenopausal. The etiology and prognosis of malignant transformation of this benign condition remain unknown...

INTRODUCTION: It is rare for primary tumors to arise from the mesentery. Lymphangiomas appear as congenital malformations of the lymphatic system or benign neoplasms as a large, thin-walled, often multilocular cyst. Mesenteric infiltration is common and during surgical treatment, adjustment of structures such as the bowel and resection of the spleen may be required. Cystic mesotheliomas are rare, benign tumors that originate from the peritoneal mesothelium and are more common in women...
